All rights reserved. - Version 6 - Chapter I Introduction 2 1 Dartfish User Guide Introduction Dartfish software provides advanced video tools to enhance your training programs and improve athletic performance. The system works both during workout and afterward when time allows for a more in-depth analysis of a performance. During the workout Using Dartfish In Th eAction * , you will be able to provide instant visual feedback to your athletes. This feedback will supplement your personal coaching and allow you to maximize the benefits of using the muscle memory (proprioceptive) of your athletes and students. Thanks to a wide variety of customizable play modes, the use of video can be fully integrated into your usual activities with athletes on the field. After the workout Dartfish software's set of video analysis features allow you to create new perspectives and innovative views of your athletes' performances: You are able to compare and view performances as never before to highlight areas needing improvement. You can annotate video with text and drawings to aid and communicate analysis Dartfish's video management system helps you manage all your training videos with ease and efficiency. Share your analysis You can share your analysis with anyone, anywhere to continue the communication and learning experience. You can send video clips via e-mail, create enhanced CD/DVDs or even publish interactive analysis on the Internet. Make sense of competition footage Taggin g* is Dartfish's notational analysis tool. Use it to create a descriptive index of the key events in a game or other long video. Tagging has tools to turn your index into a focussed team feedback presentation and also display frequency statistics of each event. Tags are created by clicking a set of fully customizable buttons, or by import from your sports own statistical tools, or even from the Dartfish E as ytag app for iPhone or iPad, available from the Apple App Store. Display data on video For those working quantitatively, measurements of time, distance and angle can be made on video and recorded in a Data Table. The Data Table can even record changes in measurement or changes in position of tracked* objects. Using the Data Reader add-ons*, you can import data from any device or software that can create a CSV (character separated value) file and relate the output to what the video shows. Dartfish is also capable of simultaneously recording video and data using In Th eAction * . This allows data to be displayed or graphed on video immediately after capture. Dartfish has developed links to several force platforms but also makes its SDK (software developer kit) available to you to develop your own links. Use Dartfish special effects for unique analysis opportunities Strom otion * and Sim u lcam * are tools used by sports broadcasters world-wide to analyze and explain movement to their audience. Users of Dartfish can also benefit from these tools. Simulcam is the only way to get a realistic comparison of video when the camcorder is panning. Stromotion and ball tails * give an understanding of how performers and objects move from one position to another. © Dartfish.

Links to tutorials and training take you to where you can access free training or arrange for a local instructor to contact you. Check for updates The Dartfish team is constantly working to improve the software and many of the updates are free. Information found here will advise you when a new update is available. Closing the Start Page If you wish, you can disable the Start Page when you launch your Dartfish software by "unchecking" Alw ays dis play th e Start Page at s tartu p which is at the bottom left hand side of the Start Page. It is possible to re-start the Start Page at any time by selecting Tools > Start Page in the M en u bar. The Start Page is closed by selecting any other Dartfish module from the Toolbar or Tools m en u . 2.1.2 Displaying Dartfish Modules Dartfish is composed of M odu les - each with individual functions for analysis, instruction, sharing etc. A module is displayed in two ways: 1. by clicking the appropriate Toolbar button. 2. by selecting the module from the Tools menu in the M en u bar You do not need to close a module to open a new one - clicking on a module button automatically replaces the old one with your selection. Only the L ibrary can be simultaneously displayed next to a module. The core modules are listed below. More modules can be available based on the Dartfish software edition you purchased. Read the relevant help chapters to learn how to use them. Im porter - import video files from a range of video devices and drives. Player - playback and trimming of video clips An alyzer - comparison of clips, drawing tools, key position analysis and publishing. 2.1.3 The Library The L ibrary allows you to locate, load, manage and share video clips. It is displayed and hidden using the L ibrary button on Dartfish's toolbar. F8 keyboard shortcut - closes/opens the library; it has the same function as clicking the library button. © Dartfish. All rights reserved. - Version 6 - Getting familiar with Dartfish 9 The library module is shown below with its four main parts labeled: 2.1.4 1. The L ibrary Toolbar contains buttons used to control the appearance and content of the Item s L is t. 2. The Keyw ords View is used to locate video clips matching categories and values selected (see link). When this area displays its Folders View , the content of selected windows folders will be displayed in the Item s L is t. 3. The Item s L is t is a list of video, image and project files that can be used by Dartfish. 4. The Tray is a working area for storing video clips that you want to work with. It is used to share video clips between Dartfish modules and also share by email, CD ROM and Internet. Resizing windows You can resize windows in the workspace as follows: 1. Place your cursor near the boundary between two windows. 2. Once the cursor changes into a bar with two small arrows on either side, click and hold down the left button of your mouse. Then you can move the cursor until the window is at your desired size. The windows can be resized both vertically or horizontally. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 10 When you close the software, the new layout is saved. 2.2 Video playback The ability to control playback (play, pause, play frame-by-frame, modifying playback speed, etc.) is one of the simplest benefits of using video analysis software. To visualize a video clip, first open it by: Double clicking the corresponding file name in the Item s L is t of the L ibrary OR Drag & drop your chosen clip onto the video panel of the module. 2.2.1 The Timeline The Tim elin e is a visual representation of the video clip(s) currently loaded in a module. The overall length of the video clip is represented by the bar along the bottom of the Tim elin e. The part of the clip that will actually play is represented by the pale blue area between the cue in point ( (the Playh ead) is marked by playhead's current position. 2.2.2 ) and the cue out point ( ). The current playing position . The image displayed in a module screen corresponds to the Trimming video clips Trimming video clips, that is setting new cue in/out points, is often necessary. Perhaps because unnecessary footage has been captured at the start or end of the clip. Perhaps because you can analyze or coach more effectively if the clip is shortened to show only specific actions. Setting cue in/out points 1. Point the mouse at the cue in/out marker ( / ). 2. Click and drag to the chosen start/end point. The video display will show the selected start/end frame as you drag. 3. Release the mouse button. You can also click in the Tim elin e to position the Playhead, right-click and select Set In or Set Ou t. Once the new in and out points are set, you have the choice of saving the trimmed video © Dartfish. All rights reserved. - Version 6 - Getting familiar with Dartfish 11 clip (see Saving a new video to learn how to do this). Reset cue in/out points 1. Right-click on either the cue in/out markers or the Playhead. 2. Select Res et in /ou t Poin ts from the context menu (see illustration above). You can also select Con trol>Res et u s er's in /ou t valu es from the M en u bar. 2.2.3 Video panel controls All the different modules have some control over how video is played. The video panel controls for the Player module are shown below. Most modules will have some of these features although not all controls will always be available according to that module's specific needs. The buttons have the following functions (from left to right): Play/pau s e - becomes a pause button when the video is playing (keyboard shortcut: Space bar) Stop - also returns to the start of the clip ([Shift] + S) Step previou s - back one frame ([Ctrl] + [left arrow]) Step n ext ([Ctrl] + [right arrow]) Previou s clip - play the previous clip in the Tray ([Ctrl] + P). N ext clip ([Ctrl] + N). Hit F11 on your keyboard to display the video in full screen. Use the keyboard shortcuts listed above to control the video playback. Controlling speed A wide variety of playback speeds can be selected using the speed control, shown below. Clicking a number will position the speed cursor accordingly (e.g. 0.5). You can also click and drag the cursor to select a precise speed (e.g. 0.35 as illustrated above). Moving the Playhead You can directly move the Playhead to a new position. To do this: 1. Stop or pause the video, if it is playing. 2. Click anywhere in the pale blue area of the Tim elin e (or click and drag the Playhead left or right). - Version 6 - © Dartfish. All rights reserved. 12 2.2.4 Dartfish User Guide Repeat mode What do you want to happen when the clip(s) you have loaded finish playing? The Repeat button found in many Dartfish modules )located on the left of the speed control) offers a number of choices as shown below. Play current clip once. Repeat current clip. Play all (clips loaded into the tray) once. Play all then repeat. To change the repeat mode Click the repeat mode button. Each time it is clicked, the mode (and the button icon) will change. The tooltip (the yellow box which appears when you point your mouse at a button or control) shows both the mode that will be activated when the repeat mode button is clicked and the current mode in parenthesis. 2.3 Saving projects and videos When working with many Dartfish modules you will have the choice of saving a "project" or saving the video file resulting from the project. Saving a project When you save a project you are saving all the information that relates to the creation of that project; the video files used, the settings chosen etc. Generally you will save projects if you wish to make changes to the project to get a better result or because you wish to base a new project on the settings used previously. It is important to note that projects do not actually include the video files used by the project. For example, saving a project using two 5Mb video clips will not end up in a project file somewhere over 10Mb. It also means that if sharing projects with other Dartfish users, you will also need to give them the video files used by that project. Saving a video clip When you save a video clip you are creating a new video file that can be used by other Dartfish modules or shared with others - even those who do not have the Dartfish software will be able to play back video clips on their own computers. 2.3.1 Saving a project Select File>Save (or File>Save As ...) from the M en u bar to save a project. The type of project (and project file icon) depends on the module currently in use when saving: - Analyzer project © Dartfish. All rights reserved. - Version 6 - Getting familiar with Dartfish 13 - SimulCam project - StroMotion project If a project is saved in a M on itored folder of your L ibrary (see section Defining your library in the Library chapter), it will be displayed in the Item s L is t. If you did not save a project when changing modules, you will be prompted to do so. Select Yes to save a project. To open a saved project Double-click on the project icon in the Item s L is t Select File>Open from the M en u Bar. To start a new project Select File>N ew from the M en u Bar. If you did not save the current project, you will be prompted to do so (see above). Starting a new project will also empty the Storyboard of the An alyzer. 2.3.2 Saving a new video Select File>Save M ovie... from the M en u bar to save a new video. A wizard will guide you through the saving steps. Different wizards are shown based on the module currently opened. Video Trimming Wizard The Video Trimming Wizard will launch when the Player module is open. Complete the wizard to save a trimmed version of the clip currently loaded in the Player (see Trimming video clips to learn how to set the cue in/out values). There are two options: Replace th e origin al video clip by th e trim m ed video clip - Used to delete unnecessary footage at the beginning and end of a captured clip. Create n ew video clip in to th e follow in g folder - Used to extract video clips from a longer footage. Video Saving Wizard - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 14 The Video Saving Wizard will launch when the An alyzer module is open. Complete the wizard to save a montage of the analysis contained in the Storyboard (read the chapter on the An alyzer). The main steps of the wizard are: 2.4 1. Selecting the video settings (see Converting video) 2. Entering the file information, i.e. a file name and the category/values to classify the new video (see Organizing your library to learn more about the file name and categories) 3. Selecting the destination folder Sharing video files Dartfish offers many ways of sharing videos with athletes or other coaches. The Video Sh arin g W izard guides you through the process of selecting and compressing video before exporting it to the appropriate media. The choices of sharing destination are: M y Com pu ter - copy your video to a folder, to an external drive or to a network server. E m ail - the video clip is compressed and attached to an email in your default email program (see note below). Recordable CD or DVD - burn video to CD or data DVD directly from Dartfish. E n h an ced Recordable CD or DVD - creates a CD with an easy-to-use interface customized with your branding and contact information. In tern et - send video to a FTP location. Dartfis h TV - Dartfish's online media sharing platform. The share by email option works for any MAPI email software such as MS Outlook or Outlook Express. For other email software or web-based email like Hotmail you will have to attach video files through the software or website itself. 2.4.1 Video Sharing Wizard Loading clips for sharing The Video Sh arin g W izard is a feature of the Tray. Start by loading the video clips you wish to share into the Tray. To do this, drag-and-drop video files from the Item s L is t to the Tray. Hold down the [Ctrl] key while clicking on the files to select multiple files. Once video clips are loaded, click the tray's Sh are button. © Dartfish. All rights reserved. - Version 6 - Getting familiar with Dartfish 15 The Video Sharing Wizard The process of sharing is guided by the Video Sh arin g W izard. Three steps are common to all sharing destinations. 1. Selecting the sharing Des tin ation - Click on a destination then on the N ext> button (at the bottom of the window) to proceed. 2. Selecting which videos you wish to share. "Check" those to be shared as shown below or click the Select All button: 3. Choose the video settings (encoding profile) appropriate for the selected destination (see Video settings for information on the different encoding profiles). Specific additional information may be entered according to the selected destination. Read the information displayed in the wizard to complete these information (also see the Outputs from Dartfish - Publishing & Sharing chapter). 2.4.2 Converting video When sharing or storing video, there are two important considerations: File Size: video file sizes can be very large which can be a problem when storage space or the distribution method have limited capacity. Video s tream in g: unless video files will be played from a local drive there are likely to be limits on the rate at which data can be streamed. The amount of video data streamed per second is expressed as its bit rate. Most obviously, video played from the internet needs - Version 6 - © Dartfish. All rights reserved. 16 Dartfish User Guide to have a lower bit rate than that produced by a typical video camcorder. Networks and optical drives also impose limits on the maximum bit rate of video which can be played from them. These considerations are addressed by compressing video by means of encoding and any Dartfish process which results in the creation of new video offers a range of suitable encoding profiles. About video encoding The subject of video encoding is a difficult one involving many variables but to enable the best choice for encoding video with Dartfish it is useful to have a basic understanding of the following: Im age qu ality: Compression results in a loss of image quality – for any video format, the greater the compression the lower the image quality. Direct comparison between formats based purely on bit-rate is difficult because more recent codecs such as Windows Media 9 and H.264 achieve greater compression (smaller file size and a lower bit rate) for the same perceived image quality as older codecs such as MPEG-2 and AVI (DV). H D vers u s SD: High definition (HD) video images appear sharper than standard definition (SD) because they have higher resolution (more pixels). When Dartfish encodes video it almost always retains the resolution of the source video; so when an encoding profile name refers to HD or SD this is a reflection of the resulting bit-rate and perceived image quality and does not indicate a change in resolution. In ten ded u s e: This, more than any other factor, will influence the encoding profile chosen. For Dartfish analysis one of the Windows Media profiles is generally the best choice but if the video is being created for playback on an iPhone or upload to Dartfish.tv, one of those specific profiles might be used. If video is being created for use on the internet your web master may have a preferred video format. E n codin g vers u s re-en codin g: Dartfish processes such as Save M ovie (Player), Con vert, Sh are and Pu blis h E ven ts (taggin g) re-encode the source video using the selected profile. Changing the video format can result in a loss of quality, although this won't be noticeable unless repeated. This is not an issue for Dartfish processes which create new video; Save M ovie (An alyzer), Sim u lcam /Strom otion , An alys is recorder. Dartfish encoding profiles A complete list of Dartfish encoding profiles, their bit rates and suggested use can be found in the Options ( Tools menu > Option s > E n codin g Profiles ). The different formats available are summarized below Form at In ten ded u s e Windows Media Windows media encoding offers a good quality to compression ratio and is the preferred option for producing video from Dartfish when the output will be played on a computer's media player or in Dartfish. Windows media video can also be used for internet but your website administrator may prefer another format. Windows Media for Analysis Recorder Highly compressed and reduced frame rate WMV used by the Dartfish An alys is Recorder to encode video (Pro and TeamPro editions) MPEG-2 MPEG-2 video is produced by many camcorders and is also the encoding used for DVDs. These profiles will be the preferred encoding for users who wish to maintain a library of MPEG-2 video or who produce DVDs. To carry out analysis tasks Dartfish needs to create an index for each MPEG-2 file. Encoding by Dartfish creates the index but if the file is moved or shared with other Dartfish users the index needs to recreated, which delays access to the file. This may be a reason for some users to avoid MPEG-2. © Dartfish. All rights reserved. - Version 6 - Getting familiar with Dartfish 17 MPEG-4 (H.264) The MPEG-4 encoding profiles are used to produce H.264 encoded video for playback on mobile devices and YouTube. AVI (DV) AVI (DV) is the video format created from camcorders using DV tape. AVI (DV) is an old format which is less compressed than WMV or MPEG and this encoding will be primarily used by tape camcorder users who wish to maintain a library of DV video. Dartfish.tv encoding profiles Contributors to Dartfish.tv can download the encoding profiles used to produce video for their channel. Use of these profiles offers the possibility to create video which is already encoded, thereby speeding up the publication process. These profiles can be exported/imported to distribute within an organization. SWF (Flash) Flash encoding is only used by Dartfish to create video for Analyzer Mediabooks. Video Settings in the Sharing Wizard The Video Sharing Wizard includes a Video Settin gs step in which you can choose to share the original video, or re-encode it. Video Conversion Wizard Existing Video files on your hard drive can be converted to a range of other video formats with the Video Con vers ion W izard. The process is as follows: 1. Select files from the Item s L is t or from the Tray. Multiple files can be selected by holding down the ctrl key and clicking each file. 2. Point at one of the selected files and click the right hand mouse button 3. Select Con vert from the context menu that appears. The subsequent process of choosing file format and location is the same as that for saving new movies but you are reminded to pay special attention to whether you want to replace the existing file or create a new file with a different name. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 18 2.5 Remote controlling Dartfish Many of Dartfish's buttons and controls can be activated by the remote control which is issued with all Dartfish editions except Connect and Classroom. During coaching sessions you are free to move and interact with your athletes and not your keyboard or mouse. In fact, it is one of the many features that the Dartfish team have put in place to help video analysis work in the real world. The remote control works with an infra-red receiver which connects to a USB port. The range of use depends on weather conditions, other sources of infra red interference and how fresh the batteries in the remote control are. You can typically expect around 25 meters. 2.5.1 Installing the remote control The infrared remote control receiver must be connected and software drivers installed. Software for the remote control is optionally installed from the Dartfish software installer but is not automatically installed with the software. The remote control will not function if its software is not installed. To install the remote control drivers: 1. Insert the software installation disk and wait for the list of options to be displayed. 2. Choose Drivers from the list of choices 3. Choose Streamzap remote Full instructions are given in the help documentation available with the installer. When the receiver is connected for first time use, Windows will detect the new hardware and install the drivers for that USB port. Depending on your Windows setup this is a two step process: 1. In the first step, Windows asks whether you want to go online to search for drivers. The answer to this is No, not this time. Driver software is already available as part of the Dartfish installation. 2. In the second step you are asked if you want to install manually or automatically. The answer is Automatic [Recommended]. This is the recommended and default option. Now Windows should successfully install drivers software for the infra red receiver. © Dartfish. All rights reserved. - Version 6 - Getting familiar with Dartfish 19 If you do not have administration rights to install software on your computer you will need to get the administration login or find an administrator to help you. Drivers need to be installed for each USB port to which the IR receiver will be connected. Trouble shooting installation Look for the Dartfish Remote icon in the system tray area of the Windows taskbar: If it is red: The remote control is installed and functional. Ensure that the receiver is pointed towards the remote control, batteries are fresh, the receiver is within range and there aren't other sources of infra red interference - the flashing red light on the receiver confirms when an IR signal is received but not whether it is strong enough or from which source. If it is grey: The remote control software is installed but the IR receiver is not connected. If it is connected to a USB port the likelihood is that drivers are not installed for that USB port correctly. Try removing the receiver and connecting it to a different USB port. If it is not present: In a small number of cases the Streamzap software does not automatically start after installation. In this case you can force it to start by restarting the computer or manually activating its executable file at /program files/Streamzap/Remote/ zremote.exe. 2.5.2 Using the StreamZap remote The Streamzap remote controls many of the functions in different Dartfish modules. Remotes issued after summer 2005 now have the function of each button printed on the control. We recommend that you become familiar with these buttons and how they can help you coach more effectively. For older Streamzap remotes you can use the following guide to the equivalent buttons on your control. If this looks like too much to remember how about starting with the group of 6 buttons under Play and Pau s e. Next use one of the 2 buttons to Start captu re. You can learn the rest as you find you need them. - Version 6 - © Dartfish. All rights reserved. 20 Dartfish User Guide Now that you can use Dartfish remotely you should be able to display video in full screen. Type [F11] or look for the Fu ll Screen bu tton on the remote. 2.6 The next steps In this chapter, you learned the basics of Dartfish software. Your next step is to learn how to get video from your digital camera onto your computer so that you can experiment with your own video straight away. Read the Capturing Video chapter. You can learn more about how Dartfish can help you find relevant video files with the Organizing your library chapter. It will explain in detail the advantages of using categories to classify and find your video clips. © Dartfish. All rights reserved. - Version 6 - Chapter III Video Library Dartfish User Guide 22 3 Video Library The Video Library is a complete set of features used to locate and manage the files you wish to analyze or share: The video library is "built" from the Windows folders containing those files that are relevant for use with Dartfish. Because you are likely to analyze many video files, Dartfish helps you locate relevant content using a flexible video content management system called Keyw ords w h ich allow you to describe the content of video clips more comprehensively than relying on organizing video into different Windows folders. Dartfish uses a L ibrary module which offers rapid access to your content as well as a variety of tools to help you locate relevant video files. The L ibrary module has a powerful sharing feature called the Tray. It provides a workspace containing files which are being worked with. This not only makes them readily accessible for use in Dartfish but also allows you to both archive on CD/DVD and share its content by a variety of media including email, Internet and CD ROM. In this chapter you will learn how to: Define your library. Learn how to include the content you wish to see in the Dartfish L ibrary. Organize your library using Dartfish's Keyw ords . Import files to the library - either by capturing new video files from a video camera or using files given to you by other coaches or athletes. Locate video files using Dartfish's array of search tools. Create Playlists from the contents of the library. Share video files by email, CD/DVD or Internet. Convert video clips. 3.1 Defining your library The library is the collection of ALL the video files that you want to use with Dartfish. These files can be stored on several folders on your hard drive. To define the library you must tell Dartfish which folders to monitor. Only the video clips found in these folders will show in the L ibrary module. The default monitored folder is the windows Videos folder To add the contents of a folder to the library 1. From the menu bar, select Tools > Option s (or type F3) 2. Click on the L ibrary option © Dartfish. All rights reserved. - Version 6 - Video Library 3.2 23 3. Click on the Add... button. A browser window will open. 4. Chose a folder and click on OK. The sub folders of this folder will also be included in the library. 5. Repeat steps 3 and 4 to add additional folders. 6. To remove a folder from the list, click the folder in the list and click on the Rem ove button. The Library workspace The L ibrary module is your route to accessing the content of the library. It is displayed and hidden using the L ibrary button on Dartfish's toolbar. The library module is shown below with its four main parts labeled: - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 24 3.2.1 1. The L ibrary Toolbar contains buttons used to control the appearance and content of the Item s L is t. 2. The Keyw ords view is used to filter the Item s L is t for video clips matching categories and keywords selected. When this area displays its Folders view , the content of selected windows folders will be displayed in the Item s L is t. 3. The Item s L is t is a list of video, image and project files that can be used by Dartfish. 4. The Tray contains thumbnails of recently created or opened videos. Think of it as giving you quick access to the files you are currently using. The Library Toolbar The function of the L ibrary Toolbar's buttons is to help you locate the items you wish to use from the Item s L is t. These buttons have the following functions: Keywords button - to display a list of categories and values by which the Item s L is t can be filtered. To learn more about doing this see the topic Locating video files. Folders button - this displays a list of Windows folders. The Item s L is t will show the contents of the folder selected from this list. © Dartfish. All rights reserved. - Version 6 - Video Library 25 View Type button - to control how items are represented in the Item s L is t. Items can be displayed in a simple list or showing details such as file size and category/values used. The thumbnail views show an image of the first frame of video. Back/forw ard navigation buttons - As different categories and folders are selected from the Folders view or Categories view the Back and forw ard buttons become available to navigate between them. 3.2.2 The Items List The Item s L is t is a list of items that Dartfish is able to use. This includes video clips, images and Dartfish projects, each represented by its own icon examples of which are shown below: - Video clips - Picture files - Analyzer projects - SimulCam projects - StroMotion projects File management using the Ite m s L ist File management functions such as file renaming, deletion and copying can be carried out from the Item s L is t. Display the range of options as follows: 1. Point the mouse at the item(s) you wish to edit. 2. Click the right mouse button. A context based "Quick menu" appears. 3. Left click the function you wish to use. The use of the Con vert function is explained in the topic Converting video clips. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 26 Opening video clips There are three methods of opening a video file from the Item s L is t: 1. Point at the item and double click the mouse. 2. Drag and drop the item from the Item s L is t on to the video display. This method offers more flexibility when there is more than one video display to choose from. 3. Drag and drop the item onto the Tray section of the L ibrary module. From here it can be added to the video display as needed. Opening Projects Projects must be opened using the relevant Dartfish module. Either the appropriate module is opened first or, if a project item is double clicked (method 1 above), the appropriate module will start, closing the current module if necessary. Opening Images Image files can be opened by double clicking them however they will not be opened into Dartfish, instead the default image viewing software on your computer will be used. 3.2.3 Item Properties Further information about items can be revealed by using the Details view or the properties window. Details View Details view is selected by clicking the View Type button on the L ibrary Toolbar. The details view reveals additional file and categorization information about each item as shown below. These details can be exported as a CSV file see the topic Exporting keyword data. The Properties window To display an item's properties: 1. Point the mouse at the item. 2. Click the right mouse button. A context based "Quick menu" appears. © Dartfish. All rights reserved. - Version 6 - Video Library 3. 27 Select the Properties ... option. The properties window appears for the selected item as shown below. Although much of the properties information is similar to that displayed in Details view, there are two useful pieces of additional information: File location - the folder on your hard drive where this file is located. The Open Con tain in g Folder button allows you to open this location to see other content of this folder. Comment - comments can be edited in the properties window and can be used to provide additional information about the file. This is particularly useful if you intend to share the file (see Sharing video files) as your comments will form part of the content of an E n h an ced CD. The Properties window - source info tab The properties window also shows information about the video source. Some of these properties can be modified to correct errors in the video. See Correcting video property errors - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 28 3.2.4 The Tray The Tray is a working area for the collection of video files currently being used. It allows you rapid access to files you want to analyze and provides a method for taking files from one module to another. Additionally, organizing items into the Tray is the first step for: Sharing video files (see Sharing video files). Adding clips to the Tray Items will appear in the Tray when: Video clips are opened from the Item s L is t. New clips are captured from a video camera. Video clips are added by drag & drop from the Item s L is t. Clearing the Tray Selected items are removed from the Tray by clicking the Clear button. If no files are selected the entire content of the Tray is cleared. File management using the Tray The items appearing in the Tray are a representation of the original file so unsurprisingly, the file management functions available to items in the Item s L is t (see The Items List) are also available to items in the Tray. 1. Point the mouse at the item(s) you wish to edit. 2. Click the right mouse button. A context based "Quick menu" appears. © Dartfish. All rights reserved. - Version 6 - Video Library 3. 3.3 29 Left click the function you wish to use. Organizing your library Your Dartfish software includes a versatile video management system called Keyw ords . The Keyw ords are used to describe the contents of your video clips in a simple and clear manner. For example, you can define categories such as the name of the athlete, discipline, location of the filming, assessment of performance etc and each video clip can be classified and easily located by using Keywords in any or all of these categories. Continuing this example, it becomes very easy to locate videos containing "John Smith" doing "Bench press", "Incorrectly" and distinguish these from video of other athletes or even of "John Smith" throwing the "Javelin". 3.3.1 Understanding Keywords To understand the Keywords system, you must be able to distinguish between the following elements: The File N am e that is defined for each video clip physically stored on your hard drive. A video clip is identified with the icon illustrated below, with the file name displayed underneath (as you can see in Windows Explorer). The Keywords that represent the details of each clip. For example "Swing" and "Front" can be used to describe a video clip containing a swing filmed from the front in golf. The process of classifying consists of assigning keywords to your video clips, i.e. labeling them. The Categories that group the Keywords of the same kind. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 30 3.3.2 Defining your categories To help you decide what categories and keywords you need, imagine you have several hundred video clips on your computer. How would you label each one to identify it? When you look for these video clips one year from now, what might you be looking for? Perhaps you film different sports or different disciplines within a sport. For this create a Sport category or a Dis ciplin e category with values for each sport or discipline that you work with. Perhaps you will want to compare video clips filmed from the same angle. That will be much easier if you are able to distinguish clips filmed from the front and ignore those filmed from the side. In this case, you may use the category Cam era An gle. So, what else might you look for? Age grou p perhaps if you want to compare athletes of a similar age; An As s es s m en t category if you want to be able to distinguish video where a skill is performed well from where it is performed badly. Once you have replied to these questions, you can create the nomenclature that will allow you to classify and locate your video clips. 3.3.3 Editing categories To create a new Category 1. Click on the N ew button at the top of the library and select N ew category... from the menu that appears. 2. Enter the name of your new category (e.g. Camera angle) and click OK. © Dartfish. All rights reserved. - Version 6 - Video Library 31 The new category will appear in the Categories list. To rename a category: 1. Right-click on a category label and select E dit... from the context menu 2. Type the new name and press the enter key on the keyboard. To delete a category: 1. Click your mouse on a category to select it. 2. Click on the Delete category or valu e button in the category tool bar 3. Confirm the action by clicking OK. The category will disappear from the Categories list. . When a category is deleted all keywords within that category are also deleted. Video clips using those keywords are not deleted but they will lose the deleted values. 3.3.4 Editing keywords Keywords appear beneath the category headings. If needed, click on the arrow sign to the left of a category to expand its list of corresponding keywords. In the example below "Event" is the category and "highjump", "javelin"... etc are the keywords used to describe the video clips. Creating, deleting and renaming keywords is done in the same way as for categories (see Editing categories) except that you start by selecting the category which contain the keyword. 3.3.5 Classifying video clips Once your categories and keywords have been defined, you can classify your video clips. This process consists of assigning keywords to your video clips, i.e. labeling them, in the same way as you would label your suitcase to help you recognize it. It is not just video clips that can be classified; any item that Dartfish lists in it's Item s L is t can be categorized to make it easier to locate. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 32 To add a keyword to an item: 1. Select the item(s). 2. Drag the item on to the desired keyword. Remember that you are not limited to adding a single keyword. You can repeat this process as often as you like BUT only one keyword from each category can be added to each item. You can classify several video clips at once. To do this, press on the Shift or Ctrl button on your keyboard while left clicking with your mouse on the clips you wish to classify. Then drag and drop the files to a keyword as described above. To change the keyword attached to an item: 1. Select the item(s). 2. Drag the item to a different keyword within the same category. It is often better to add keyword to your video clips as they are captured from your camera. To find out how to do, see the topic Setting Clip Properties 3.3.6 Removing keywords from video clips As seen in the Editing categories topic, deleting a keyword from the categories list will also remove that keyword from any items which hold it. However it is also possible to remove a keyword from a video clip. To remove a keyword 1. Click the View Type button at the top of the L ibrary module 2. Select Details . 3. Alter the width of the Item s L is t so that you are able to see the headings for each category (these are only visible in Details or Th u m bn ail Details views). To do this you will click and drag the right hand border of the Item s L is t. 4. Find the keyword you want to remove. To do this you may have to make the Item s L is t wider still or use the scroll bar at the bottom of the Item s L is t. 5. Right click on the value and choose Ren am e from the context menu. The keyword will enter an editing mode as shown below: © Dartfish. All rights reserved. - Version 6 - Video Library 6. 3.3.7 33 Delete the existing keyword ( Backs pace key on your keyboard). Importing/exporting keyword sets The category and keyword information for each video clips is stored in a small extra M etadata file (with a ".dartclip" file extension). Although this is not visible in Dartfish's Item s L is t you can see it using Windows Explorer as shown below. When your video clips are shared, the recipient will also inherit a new set of categories and keywords provided the metadata file was also shared. All Dartfish's sharing processes include metadata. What happens when inherited categories match existing categories? Provided that the spelling and capitalization is identical, the new video clips will fit neatly into the existing keyword system. But if, for example, the new video clip has a value of "F ront View" and you use a value "front view" then both keywords will now appear in your "View direction" category. When you and your fellow coaches will use the same categorization system (or you have more than one computer) you can export a set of Category/keywords from one computer to another. Exporting Categories/keywords 1. Click the Add a n ew category or keyw ord button 2. Select the E xport keyw ord s et... option. 3. Save the export file. . Make sure you know where the export file has been saved as it will be passed (by disk, network or email) to the other coach or computer. Importing Categories/keywords 3.3.8 1. Click the Add a n ew category or keyw ord button 2. Select the Im port keyw ord s et... option. 3. Locate and open the file to be imported. The new categories and keywords are now visible in the Keyw ords view . . Exporting keyword data Dartfish allows the export of the video library's keyword data in a CSV file that allows the data to be stored and analyzed in databases and spreadsheets. keywords associated with video files contain a lot of information that may be of more benefit than assisting with finding and identifying the content of video files. For example, - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 34 specialist shoe shops gather information about the shoes that customers buy as a result of video analysis; researchers making observations from video may record that information using keywords. To export Category/keyword data as a CSV file 1. 2. 3. Use the search and filter tools to isolate the video clips with data to be exported. Point the mouse anywhere on the Item s L is t and click the right mouse button. Choose E xport L is t from the context menu that appears. 4. Save the CSV file. It can be reopened by spreadsheet software such as MS Excel. It is not necessary, but it may help, to change the library view to one of the details views. This will allow you to see what data is held for each file prior to export. To do this: 1. Click the View button at the top of the library. 2. Select details or th u m bn ail details view. © Dartfish. All rights reserved. - Version 6 - Video Library 3.4 35 Importing files to the library Dartfish imports files to its library by one of two processes; Video Recorder or Video file Im porter. Access to these tools is via the Im porter button on the toolbar which allows you to select one of these tools by accessing its drop-down menu. If you are not sure which tool is best for you, click the Im porter button itself and choose from a list of video devices and sources. Dartfish will then start the correct tool according to your choice. Video File Importer Copies files from any disks or folders internal to, or connected to, your computer. This includes: Camcorders recording to hard-drive or internal memory DVD camcorders DVDs or CDs in your computer's optical drive Card readers Folders on your computer, network or external drive. Video recorder Records a live feed from a device capable of delivering a video stream; this is recorded by Dartfish to create new video files. The most common instance of this being the replay of recordings on the tape or the live stream from a DV or HDV camcorder (uses DV tape cassettes). This method also applies to any device providing a live video stream, for example: DV and HDV camcorders as described above Video converter devices (analog to digital, HDMI to DV etc). These devices are used to convert the video output from devices which don't provide a digital stream Webcams The video feed from webcams is often of low quality and frame rate making them unsuitable for effective analysis. Those using them should also be aware that the images are uncompressed and therefore require greater processing by your computer. Other ways of adding files to your library For the sake of completeness, there are 3 further ways in which files can be added to your library: 1. A new folder is added to the list of folders monitored by Dartfish (see Defining your library). 2. The results of a Dartfish project are saved. 3. Video files are copied or saved into the library by a process external to Dartfish, for example by using MS Windows file management tools or by using the import software supplied with many camcorders. When new files are added to a monitored folder by an external process they won't automatically appear in the Library - you must remember to refresh. From the menu bar - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 36 choose View > Refres h . 3.4.1 Using the Video File Importer The Video File Im porter copies files from any device on which Windows is able to recognize a file structure (for a fuller description see Importing files to the library). To import video files into the library: 1. Connect the external device or insert media into the appropriate drive. If the device doesn't simply plug and play you may need to refer to the device's documentation to learn how to do this. For example, many camcorders require that you select a connection mode. 3.4.1.1 2. Select Video File Im porter from the drop down menu on the Im porter button. 3. A step-by-step Wizard is launched to guide you through the process of selecting, copying and categorizing video files. The steps of the wizard are covered in the following topics. Video File Importer - selecting files In the first step of the importer you choose the source of your files and then can select or deselect which files you wish to import. Select source drive Select a device or select the Brow s e... option to select a specific folder. Even if you made a specific choice of video source from the importer, all connected sources are listed. When selecting the source remember it may not always be obvious how your computer identifies your device; in the example below the camcorder is simply identified as "Removable Disk (G:)" Dartfish automatically recognizes the file structure on certain devices and displays the videos from that device. On other devices it will be necessary to browse and select the appropriate folder. Select Files Files are selected by placing a tick in the check box at the top right of the thumbnail. Proceed to the next step by clicking the N ext button at the bottom of the Importer © Dartfish. All rights reserved. - Version 6 - Video Library 3.4.1.2 37 Video File Importer - naming and filing videos In the final 2 steps of the wizard you will define file name, assign keywords and select a folder for the imported files. File name The title has two roles depending on the source device type: For sources which Dartfish will join concurrent files (AVCHD camcorders and DVD), the title represents the name of the new file that will be created. For other sources, the file name allows you to rename the often meaningless name assigned by the camcorder. The same filename will be used for all imported files but suffixed with an index number e.g. filename(1) Add keywords to video clips Dartfish keywords can be added to video clips as they are imported. As discussed in the Organizing your library topic, keywords are a highly effective way of cataloging video content. To add a keyword: 1. Click the Add Keyw ord Category button 2. Select a keyword category, if the category doesn't yet exist in your library, type the new category name to create it. 3. Select or type the keyword to be assigned 4. Repeat as often as required to fully describe the video content The keyword form is retained for future imports Previous versions of Dartfish automatically added the keyword "Import session dd-mmyy" to imported files. Now there is flexibility to add any keywords but it may still be useful to add a keyword representing the name of the session in order to be able to easily locate all the clips from a single session. Select destination folder The final step before import allows you to choose the destination for imported files. This is the Windows folder where your files will be stored. Even if you use keywords to organize your library, your files are still stored using the Windows folder system. It is perhaps best to import to one of your library's monitored folders but any folder you choose will automatically be monitored by Dartfish. It is recommended that you choose a folder on a local drive, rather than on a network; this will ensure rapid copying and smooth playback and analysis The folder structure of the removable media will be maintained after import. For example if my memory stick contains a file K:\Videos\file.mpg it will be imported as ..\destination folder\Videos\file.mpg. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 38 Finish Your final choice is whether you wish the imported media to be included in the Tray. Regardless of the choice made, of course all media can be located in the Library Item s lis t. Categories can be used to help locate clips from a specific import session. 3.4.1.3 Notes on the Video File Importer Importing files from Camcorders Many camcorders permit a maximum file size so when you make long recordings several video clips are created. For certain types of device (currently AVCHD camcorders and DVD) Dartfish automatically detects sequential files and creates a single video clip. Indexing video MPEG-2 (and some other video formats) do not have an index, preventing accurate identification of video time position. Tasks which rely on this, such as stepping through the video and synchronizing multiple clips, become unreliable. Dartfish creates an index when these videos are imported or opened. Access to the video is delayed during indexing, but the index is retained allowing immediate subsequent access. Importing from DVD In addition to importing files from data CDs/DVDs and importing from DVD camcorders via a USB connection, Video File Import copies video files from a video DVD in a form that can be used in Dartfish software : the DVD's VOB files will be renamed with an MPG file extension to allow them to be played by Dartfish. DVD import is not designed to captu re video images from a DVD player. In order to import DVDs your computer must have a disc drive capable of reading DVDs or import is direct from the DVD camcorder connected by USB. If your computer's DVD player automatically plays the disc after insertion, stop it and close the player to allow Dartfish to access the disc. Many commercial DVDs are copy protected. Dartfish will be unable to import video files from copy protected DVDs. Video DVDs that have been created by a home DVD Video Recorder or a DVD camcorder are usually not copy protected. 3.4.2 Video Recorder: get video from DV tape camcorders Video Recorder is the Dartfish module which is used to record video from DV tape camcorders and other devices providing a video stream. In this topic we focus on the process for DV tape camcorders: other devices will follow similar steps but the connection process will vary. Its use is very simple - three steps to set it up and three steps to capture each clip. These steps are shown below but for further details, read the rest of this topic. To activate DV import 1. Select Video Recorder from the drop down menu on the Im porter button. © Dartfish. All rights reserved. - Version 6 - Video Library 39 To setup DV Import 1. Connect camera to computer via Firewire 2. Switch camera ON to "Camera" or "VCR" mode. 3. Set capture settings if needed. To capture video 3.4.2.1 1. Play video tape to find relevant footage 2. Start capture 3. Stop capture Setting up capture Connecting a camera A DV camera is connected to a computer via a firewire cable (also known as IEEE 1394 or i-link). In general, your camcorder will have a 4 pin connector. Your computer can either have a 4 or a 6 pin connector. The cables are called 4 to 4 or 4 to 6. "4" pin connector "6" pin connector - Version 6 - © Dartfish. All rights reserved. 40 Dartfish User Guide Switching the camera on To capture images from tape, switch on your camera to "Play" or "VCR". If this is the first time that a DV camera has been connected, it may take some moments for Windows to install the new hardware. Watch for progress in the Windows system Tray. Selecting a C aptu re D e v ice The lower part of the DV import module contains several settings. Clicking the headings expands each setting to view the details. In the Captu re Device section the video (and optionally audio) devices are selected: Select your camera from the Select captu re device drop-down list. When a successful connection to a camcorder is established the Record button will be active (red) and when the tape is played an image should appear in the DV im port video display . If the device or camera that you are using does not appear in the capture device list, it is possibly because of one of the following reasons: Camera not switched on. (Remember cameras auto switch off after a short time if unused) Correct cable not present or disconnected ( a firewire can easily work loose). Camera not properly installed and recognised by Windows. Hardware fault with firewire cable or camera or capture card. Camera not capable of exporting video to a computer. 3.4.2.2 Setting Clip Properties Use the Clip Properties to set the File N am e, Categories and Keyw ords for newly captured clips. This information defines a so-called Captu re Form that will be used to categorize the video clips during capture. Read the section Organizing your library to learn more about categories and keywords. Defining the C aptu re F orm © Dartfish. All rights reserved. - Version 6 - Video Library 41 1. Click the Add a category link . The Add Category dialog will appear. 2. Select a category from the list or create a new one. 3. Click OK. A new category box will appear on your Captu re Form . 4. Repeat steps 1-3 until boxes for all the categories you want to use are displayed on your form. Using the C aptu re F orm 1. Type a file name in the file name text box. Each file captured using this file name will be numbered sequentially. For example if you type "Training Apr10", each captured clip will be named Train in g Apr1 0 (1 ), Train in g Apr1 0 (2 ) etc. The filename you use must follow MS Windows file naming rules: Max length 256 characters; use of ":", ";", "/" or "\" is not possible. If no file name is specified a generic name of U n titled(1 ) etc will be given. 2. Select the keywords you wish to give the clip by selecting them from the drop down list for each category box. For example, you might intend to capture all of the men's Giant Slalom competitors in Chamonix. Your form should look like this: - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 42 If a keyword does not already exist, for example a new competitor, you can type that value into the appropriate box. This new keyword will only appear in the L ibrary module's categories list after clips have been captured. If a category is to remain with no keyword, for example if the name of a competitor is unknown, the value may be deleted from that category box (select it and use the Backs pace key on your keyboard). Do not use the Clear bu tton as it will remove the category box from the form. 3.4.2.3 Using Recording options A difficulty when capturing from tape is to guess when the action that is to recorded starts. It is common to start recording too early and create a file that is longer than neccessary or needs to be trimmed. Worse still, recording is started too late and the only option is to delete the file and try again. Recording options are intended to prevent this. There are two recording options: Pre-record - constantly stores a defined number of seconds of video in the computer's memory. When recording is started the stored video is included in the video file created. Setting one or two seconds of Pre-record compensates for user and computer reaction time. Recordin g Du ration - it is possible to define how long the captured clip will be. Recording will automatically finish at the end of the defined duration. This simplifies recording to the single button press that initiates it but it is especially valuable when longer videos are to be recorded; for example, start recording a game and return one hour later when it has finished. To set Recording options 1. 2. 3. Expand the Recording options section Select the setting (tick box) Set the value by editing the time directly or by using the Up-Down buttons. Note that time is displayed in Hour:Minute:Second format. In the example shown here a 2 second pre-record is being used but the 5 second © Dartfish. All rights reserved. - Version 6 - Video Library 43 recording duration is not and recording will be stopped manually. Recording after the action has completed The tape may show many actions which are of no value to you. How can you efficiently select which of these you want to record for use in Dartfish? By setting a larger Pre-record it is possible to make an assessment of which actions are worthwhile. In the example below, recording is only started AFTER the jump has completed: A pre-record of 4 seconds allows for decision making time and by also setting the recordin g du ration to 4 seconds we ensure that it is always the previous 4 seconds that are recorded. 3.4.2.4 Selecting a recording location The Recordin g folder setting both displays the current Windows folder where video will be stored and allows you to select a different location.The recording location default is the "Videos" folder on your computer. To change recording location: 1. Click the Ch an ge recordin g location link. The following dialog box appears: 2. Select a folder from the list or click the M ake N ew Folder button to create a new folder in the currently selected folder. Choosing a recording folder - Version 6 - © Dartfish. All rights reserved. 44 Dartfish User Guide Apart from organizing your files where it is convenient to find them in the future you must choose a drive with sufficiently fast write-speed. Video files are large and data-rich so attempting to save to a location where the file writing speed is too slow is akin to quickly pouring a lot of water down a narrow pipe! The result is dropped frames and jerky playback. Typically, data transfer to a network location is too slow to successfully create video files. Record to a local drive and then use the Sh are function of the Library's Tray to copy the files to other locations. 3.4.2.5 Using an encoding profile Dartfish can re-encode video during capture. When no encoding is used, video is recorded in an AVI file format which is relatively uncompressed. Selecting an encoding profiles for capture is used to: Reduce video file size. Prepare the video for its final destination e.g. sharing by internet and CD Make files compatibile with media storage systems and document management systems that require video in a specific file type. About the encoding types See Converting video for further information on the different encoding profiles. Convert in Background To both record a video file and simultaneously convert it requires a lot of computing power. If the Con vert in Backgrou n d option is selected Dartfish will prioritize the recording of the file as AVI but convert it when resources are available. Creation of the encoded file may finish some time after recording has completed. Keep the original recording file Because the Con vert in th e Backgrou n d option effectively creates 2 files, you can choose to retain the full quality AVI file in addition to the encoded copy. Although encoding during capture offers the convenience of a video file already suitably encoded/compressed for its final purpose, it is possible to re-encode any video file in the library simply by right-clicking it and selecting Con vert from the context menu. 3.4.2.6 The background task manager When the Con vert in backgrou n d option is used to encode (convert) video as it is captured, the full quality video is stored by the computer until sufficient resources are available to complete the conversion. This may not happen until some time after the capture. The Backgrou n d tas k m an ager helps you keep track of the progress of creation of encoded clips and if neccessary allows cancellation of the process. To view the background task manager © Dartfish. All rights reserved. - Version 6 - Video Library 1. From the Tray section of the L ibrary, click on the Tray button. 2. Select Backgrou n d Tas k M an ager from the menu. 45 To cancel tasks If the progress indicator for a task shows that it is not yet complete then the task can be cancelled by clicking its close button . Clicking the same button on completed tasks does not undo the process, it simply removes the item from the list. All complete tasks can be removed by clicking the C lear button. This may help in identifying which tasks are still incomplete. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 46 3.4.2.7 Capturing video to Library Once setup, the process of capturing video is a simple one; you have to locate the position on the tape where the footage of interest is recorded and then click a single button to start and then stop capture at the beginning and end. Finding footage on tape The DV Import module has a set of controls that you can use to control the camera. Alternatively, you can use the equivalent controls on the camera itself. Capture video Click the record button at the start and end of the clip. The pause recording button allows you to pause capture while the tape continues to run. This allows you to create a single clip when the action is split. For example, coach intervention in the middle of a trampoline routine or a fall while skiing can be ignored. Replaying captured clips The clips you have captured will now be listed in both the Tray and Item s L is t of the L ibrary module. Load the video by double clicking on it. The video clip will open in the Player module. 3.5 Locating video files Dartfish's L ibrary module offers three methods for helping you to locate specific video files from the Item s L is t. Keywords view - displays a list of categories and keywords. The Item s L is t is filtered to reflect files matching categories and keywords selected. Search - the search box allows a text based search of filenames, categories and keywords of the contents of the library. Folders view - the typical way of locating files using MS Windows folders. The Item s L is t displays the content of the selected folder. 3.5.1 Using Keywords When using the Keywords system all video clips (and other Dartfish projects) in the L ibrary will be listed in the Item s L is t. That could amount to a lot of files! You can filter the Item s L is t to show only relevant clips by selecting the categories or keywords for those clips. Filtering the Ite m s L ist by category 1. Display the Library module 2. In the Categories L is t, click the box next to the category of video you want to search © Dartfish. All rights reserved. - Version 6 - Video Library 47 for. A binocular symbol appears in the box and all values within that category will also be selected 3. The Item s L is t will display all clips which are labeled with keywords from that category. Filtering the Ite m s L ist by keyword 1. In the Categories list, click the [+] symbol next to the category containing the keyword you want to filter by. An expanded list of keyword is displayed. 2. Click the box next to the keyword of video you want to search for. A binocular symbol appears in the box. The Item s L is t will display all clips which are labeled with keywords from that category. You can select multiple keywords to refine your search Removing filters 3.5.2 1. EITHER: Click the box next to each category or keyword that you want to exclude from the filter such that the binocular symbol disappears. 2. OR: Click the Sh ow All button above the Item s L is t. Using Search When using the Categories view, a search box can be found above the Item s L is t. This can be used to search for all or part of the text in the file name, keywords and categories of a video clip. For example a search for "Golf" could yield the following results: - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 48 To use the Se arch : 1. Type search text. 2. Click the Search button or press the ENTER key. Combining Se arch and keyword filters When keywords are used to filter the Item s L is t, search results are based around the selections made as follows: Search first - subsequent category/keyword selections filter the search results only. Filter first - subsequent searches are based on filtered results only. 3.5.3 Using Folders The Folder view creates a way of searching drives and folders on your computer for items. Although we recommend the use of keywords as a more versatile method for cataloguing your video library there may be occasions where you prefer to identify video clips by the folder where they are located. For example if you want to examine the contents of a CD or networked drive (including these types of location in your video library is not recommended). Filtering the Ite m s L ist by folder content 1. Display the Folders view by clicking the button at the top of the library. 2. In the Folders view, click the folder you want to examine. 3. The Item s L is t will display all clips in the selected folder. © Dartfish. All rights reserved. - Version 6 - Video Library 3.6 49 Saving the tray's content The contents of the Tray can be saved as a Playlis t which can be reopened in the future. This is useful for any situation where you will want to work with a collection of clips; creating a Playlist will be more efficient than locating the same clips in the items list for example: A set of clips illustrating techniques to be practiced in a coaching session. Clips captured during training which you want to keep together for later feedback or editing. All video sources used while Tagging a game (Team Pro). 3.6.1 Creating a playlist A Playlist is created by saving the tray, to do this: 1. Click the Tray button found to the left hand side of the Tray itself. 2. Select the Save Playlis t... option. 3. Enter a file name and select a folder location for the Playlist. Playlists can be saved into any folder you like but if you select one of the library folders (see Defining your library) your Playlist will appear in the items list with the following icon: This allows you to categorize, search for and open clips in the same way as you would with - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 50 video clips. 3.6.2 Reusing a playlist A Playlist is used by opening it, to do this either double-click its icon in the Item s L is t or proceed as follows: 1. Click the Tray button found to the left hand side of the Tray itself. 2. Select the Open Playlis t... option. 3. Locate the file on your computer and click the Open button. When a Playlist is created it does not duplicate the video clips it contains but simply instructs Dartfish where the original clips can be found. If a clip contained in a Playlist is moved to another folder, deleted, or the folder containing it is unavailable (for example, a disconnected network folder or external hard-drive) then Dartfish will be unable to find it. When the Playlist is opened you will be offered the opportunity to find the clip. If the N o button is clicked the Playlist will continue to open the remaining clips (and continue to warn you if the files are not found). Remember to save the Playlist if you wish the changes to be permanent (see Modifying a playlist). 3.6.3 Modifying a playlist Once the Tray's content has been saved as a Playlist, changes made by adding or removing clips from it are not automatically saved. These modifications must be saved using the same procedure as creating the original Playlist (see Creating a playlist) You have the choice of saving a new Playlist with a new name or overwriting the original. 3.7 Sharing video files The Tray is used to share video to a variety of destinations including network drives, email, CD and internet. To learn more about all the outputs from Dartfish see the Dartfish outputs - publishing & sharing chapter 3.8 Converting video clips The video which comes from your camera is in a DV (.avi) format. It is possible to use Dartfish to convert DV video files into other, more compressed formats to reduce the space they occupy on your hard drive. Conversion is guided by the Video Con vers ion W izard. 1. Step1 - select the files to convert from the Item s L is t or the Tray. To select multiple files, hold down the [Ctrl] key while clicking on the file names. 2. Step2 - Display the Tray or Item s L is t context menu by right-clicking on any of the selected items. Select Con vert to launch the Video Con vers ion W izard. © Dartfish. All rights reserved. - Version 6 - Video Library 51 3. Step3 - Video Settin gs . Select an encoding profile. The profile chosen affects the video format and the degree of compression. For more on video encoding profiles see Converting Video in the Gettin g Fam iliar chapter. 4. Step4 - Des tin ation . Choose a destination folder for the video. The default is to return converted video back to the same folder as the original files. Converted clips will not replace the originals and will have a different file name. For example, "Marathon.avi" will become "Marathon.wmv". However, you are able to choose what action to take if there are other files with the same name located in the destination folder. You can either overwrite the existing files or rename the converted files. Clicking the N ext button at this stage starts the conversion. When complete, the new files can be found in the Item s L is t or Tray. 3.9 Video Formats and Dartfish Dartfish can play a variety of common video formats. This allows the use of video content from a variety of sources and devices. The following formats are supported. AVI (DV - PAL, NTSC - Type I & II, uncompressed and DivX) High Definition (HD) in HDV or AVCHD Windows Media (WMV) MPEG (MPEG-1, MPEG-2) MPEG4 (H.264-AVC) The file types listed above are a broad guide - some devices and software encode video files using codecs that cannot be decoded by Dartfish. Others may create files with a proprietary file extension that is not recognized by Dartfish. Our advice is to try to play it and you'll soon find out if it works! Check out Dartfish Support for further advice. HD (high definition) video and Dartfish The increased resolution of HD video can be highly beneficial for video analysis however it also has downsides. Four times more pixels can require more storage space and processing power, although this varies considerably depending on the encoding bit rate used by your camcorder. The difficulty is not just with image resolution; the complexity of encoding profiles such as MPEG-4 require five times more processing than standard definition MPEG-2. The result may be that analysis tasks such as split-screen comparison or even frame-by-frame playback require above average computer resources. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 52 For those using HD it is particularly important to be aware of the recommended computer specification. 3.10 Correcting video property errors Some video devices produce video which fails to describe, or describe incorrectly, certain video features and this can lead to problems with appearance. Dartfish allows you to manually correct video properties. To display the video properties: 1. Right-click the video item in the Library's Item s L is t or Tray 2. Select Properties from the quick-menu 3. Select the Sou rce In fo tab The following errors can be corrected: Interlacing errors Interlacing errors occur when the two fields which comprise each frame of interlaced video are incorrectly displayed. If interlaced video is incorrectly described as progressive then a characteristic jagged edge is seen on moving objects, such as shown below. Where the two fields are displayed in the wrong order, the video will appear to jump back and forwards when played frame by frame or in slow motion. Aspect ratio errors When a video is displayed in the wrong aspect ratio the image will appear distorted; squashed or stretched. To adjust properties Only properties with a pencil icon next to them can be edited. 1. Click on the value to edit 2. Select the correct value from the drop down list 3. The corrected value is displayed next to the original value as show below: © Dartfish. All rights reserved. - Version 6 - Video Library 3.11 53 The next steps This chapter covered the use of the Library and explained how to create a library using Categories and Keywords to manage video clips. Specifically, you learned to: Define folders and drives to be contained in the library. Define appropriate Keywords for your needs. Describe the content of your video clips by using categorized keywords. Capture and export video clips from DV tape. Share video by disk, email or Internet. Archive and backup video on CD. We recommend that you take some time now to define the folders and/or drives that you want in your library, create categories and values suitable for your use of video and then, if you have existing video clips, assign appropriate values to each. If continuing your journey through Dartfish Help then you might want to learn how to capture video 'live' using the In Th eAction Module (read chapter Live capture & instant replay during training). Dartfish is also able to share video by producing Media Books from the An alyzer module. - Version 6 - © Dartfish. All rights reserved. Chapter IV Live capture & instant replay during training 56 4 Dartfish User Guide Live capture & instant replay during training The InTheAction module is a combination of Dartfish capture, replay, comparison and analysis features brought together in a way that allows the delivery of video feedback during training sessions. The aim here has been to make the technology easy to use without the presence of a computer being disruptive to training itself. Some of the key features which allow this to happen are: Remote controlled - for complete ease of use, a single button on the remote control can control both capture and replay. Simplified video capture - in automatic mode only trigger capture at the start of the action. A fixed number of seconds is captured from this point. Automatic instant replay - replay happens automatically as soon as capture is complete. Pause and set replay speed by remote control. Comparison - compare captured clips side by side with a reference clip. Synchronization - synchronization of clips is based around the moment when you trigger capture making comparison of 2 clips both easy and quick. Drawing/annotation tools - illustrate coaching points using a range of drawing tools 4.1 Preparing InTheAction for use At the start of your coaching session using InTheAction you will spend a short time preparing InTheAction for use. Of course you'll need to connect the camera, perhaps more than one camera, also in this section you will learn to adapt the recording and play parameters according to your specific needs. 4.1.1 Selecting capture device IMPORTANT NOTE: About using video devices with InTheAction InTheAction works by establishing a link that allows live images to pass directly from camcorder to computer. For this reason it only works with camcorders and devices capable of providing a video stream. DV and HDV tape camcorders can do this streaming but the latest HDD and SD card camcorders do not offer this functionality. It is still possible to use InTheAction with these camcorders in conjunction with converter hardware: the camcorder's video output to TV is connected to the converter which creates a digital video stream which can be used by Dartfish. Converters can be used with analog © Dartfish. All rights reserved. - Version 6 - Live capture & instant replay during training 57 and HDMI video sources. Webcams offer another solution. They provide streaming digital video but it is often of low quality and frame rate. Even high quality webcams often lack the basic functionality (zoom, auto exposure etc) of the cheapest camcorders, making them unsuitable for creating good images for analysis. Nevertheless, webcam use may be a convenient solution in situations where the image quality is adequate for the purposes of the analyst. Those using them should be aware that webcam images are unencoded and therefore require greater processing by your computer and a faster hard drive writing speed. This can make the use of webcams problematic on less powerful computers. The latest advice on the use of camcorders and other imaging devices can be found on the support section of our website. The information below applies equally to DV camcorders and other video streaming devices. Setup capture devices After connecting the camera, the next step is to launch the InTheAction module and select your camera as its video input. To launch the InTheAction module click on the InTheAction button on the toolbar: InTheAction module has two tabs at the top of the module: Setu p In pu t Devices - to select the capture device(s); choose the appropriate device from the drop-down list. Once selected, you should see the images transferred from capture device (camera). If your device is not listed, make sure that your equipment is correctly connected (see Video Recorder in the Video L ibrary chapter), switched on and has not automatically switched off - many cameras do this after a fixed interval. Taking the tape out of the camera prevents automatic power off every few minutes. Usually input device selection is only required the first time you connect your camera to your computer. It is necessary if there is more than one input device or if several different cameras are used. In Th eAction - is where the capture and replay features are found. Click on this tab once you have selected the capture device. 4.1.2 Using more than one camera If your computer has two firewire inputs, a second camera can be connected, allowing InTheAction to capture two video clips simultaneously. For example, rear and side shots. InTheAction allows simultaneous replay of both clips. Choosing multiple video inputs Unless you choose to use multiple video inputs when you installed Dartfish you will first need to activate the option to use tw o cameras. To do this: - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 58 1. Open the Dartfish options, select Tools>Options from the Menu bar (F3). 2. Select the In Th eAction topic 3. Click the 2 (n eed iden tical device type) option Indentical devices are recommended because it requires much more computing power to process the video from different hardware. Setting up multiple video inputs 4.1.3 1. Launch the InTheAction module. 2. Select the Setu p In pu t Devices tab. 3. Select the second camera from the corresponding drop-down list Defining recording folder The lower part of the InTheAction module allows you to set the Recordin g Folder, i.e. the folder where the captured clips will be saved on your hard disk (see Organizing your library in the Video L ibrary chapter for more info). To do this, use the Ch an ge recordin g folder as illustrated below: 4.1.4 Defining clip properties If you intend to keep the video clips in your library you should define the clip properties which will be assigned to the video files that are saved. Use the Clip Properties to define: the File N am e - enter the file name in the text box the categorization of captured video clips - use the Add a category link to add a category and/or keyword (see Organizing your library in the Video L ibrary chapter for more info) © Dartfish. All rights reserved. - Version 6 - Live capture & instant replay during training 59 Once defined, these properties will assigned to all subsequently captured clips, until a new file name or category/values are specified. 4.1.5 Defining pre-record & clip durations InTheAction module lets you capture video clips in a single click. To do this, you have to specify the Clip Du ration and pre-record Du ration values. What is Re cordin g Duration? Based on the type and duration of the action that you want to record, you need to define the approximate Clip Duration of the video you are going to capture. For instance, the duration of a golf swing is approximately 3 to 4 seconds from the address to the finish of the swing. What is pre-record Duration? If you wait until you see the golfer start to swing before starting to record , you may miss the first moments of the swing. To avoid this you should set a pre-record Du ration value which corresponds to the second(s) of video footage that took place before you started capture. Pre-record forces the computer to continually remember the number of seconds you specify. When you trigger capture it includes these seconds at the beginning of the new clip. Usually just a few seconds of pre-record are required but the maximum amount is limited by the amount of available memory (RAM). When should you start capture? The moment when you trigger capture also creates a Default Syn ch ron ization poin t on the captured video. Synchpoints are used to easily synchronize video clips for comparison (see Synchronizing clips in InTheAction). For this reason it makes sense to trigger capture at an obvious point for comparison e.g. when the club strikes the ball as shown in the following diagram. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 60 To define the pre-record and clip durations. The current settings for pre-record and clip durations are displayed at the bottom of the InTheAction module as shown below. To change these settings: 1. Tick the box next to the pre-record value if a pre-record is to be used. 2. Set a value for pre-record du ration according to the advice above. The largest prerecord duration you can set is related to the amount of available RAM memory of your computer. It is possible to increase the amount of memory dedicated to storing prerecord (see About pre-record buffer). 3. Tick the box next to the recordin g du ration value if you want recording to automatically stop after a fixed duration. If this is left unticked you must start and stop recording manually. 4. Set a value for recording duration. Remember that the pre-record duration is included in the total recording duration i.e. for the settings illustrated above a 10 second clip and NOT a 13 second clip is created. If the pre-record is set to the same or greater value than the recording duration it is possible to wait until after the completed action before triggering recording. This allows you to assess whether a performance is worth recording before deciding whether to record or not. 4.1.6 Defining a replay sequence Once you have captured a video clip, the InTheAction module will replay it automatically based on the criteria defined in the Replay Sequence. By default, no scenario is used for the replay sequence and replay speed is manually controlled by © Dartfish. All rights reserved. - Version 6 - Live capture & instant replay during training 61 the user. Defining a scenario automates this. Creating a replay sequence example In the following example, a 5 second pause allows the athlete to join the coach at the computer screen, together they then view the clip once at full speed and then in slow motion. To create such a scenario: 1. Display the InTheAction options (F3 > InTheAction). 2. Activate the replay sequence function by clicking the Use a Replay Sequence check box. 3. Click the Configure Replay Sequence button 4. Click the Add Pause button and set the Duration. 5. Click the Add Replay button and set the Speed to x0.5. The Replay Sequence is ready to use and appears as shown in the following image. When using a replay sequence it is still possible to control playback (pause, play etc.) by the other video playback controls and remote control. 4.1.7 About pre-record buffer By default, Dartfish uses half the available RAM memory to store pre-record. If you are unable to set enough pre-record it is possible increase the memory bu ffer reserved for prerecord. To increase Pre-record buffer 1. Select the Setu p Captu re Devices screen of InTheAction . 2. Drag the slider to define the size of the buffer. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 62 The blue section shows the memory being used by other processes, the green section shows the memory dedictated to pre-record. The green section turning red is an indicator that more pre-record buffer than is advisable has been set. This is liable to affect the performance of Dartfish and other functions of your computer. 4.2 Instant visual feedback during training Once you have defined the InTheAction settings (see Preparing InTheAction for use ), you can start using the InTheAction module. These are the steps: 4.2.1 1. If using the remote control (see Remote controlling InTheAction ), use full-screen view (type F11). Recommended to give the largest possible video image. 2. Capture a video clip. 3. The clip automatically replays. 4. Repeat for the next action Capturing and replaying Trigger Capture 1. The camera should be in it's camera mode and the video image from the camera should be visible when using InTheAction's Live view. The choice of views is controlled by the buttons at the top left of the module; Live, Simple Replay, Blank , Comparison and Reference replay. L ive view - shows the image from the camera Sim ple Replay view - shows replay of the last captured clip or any clip opened from the Tray. Blank view - blanks the screen (prevents it being a distraction!). Comparison view - compares the replay clip with the reference clip. Reference replay view - shows replay of a reference clip. It is not necessary to be in L ive view to capture but it gives guidance that the camera is pointing in the right direction. 2. Click on the red Capture button or use the equivalent remote control button (see Remote controlling InTheAction ). The duration of the clip will depend on the Clip Duration property (see Defining pre-record & Clip durations ). Viewing: Once you have captured a clip, the replay sequence will start automatically. © Dartfish. All rights reserved. - Version 6 - Live capture & instant replay during training 63 During replay it is possible use the replay controls or the remote control to pause, change playback speed, skip to next track etc. At any point you can capture again. It is not necessary to switch from Replay view to L ive view to initiate capture. 4.2.2 Controlling the replay Replay of the clip can be controlled by using the playback buttons like on a normal VCR, or by using the equivalent remote control buttons (see Remote controlling InTheAction ). Read the Getting familiar chapter to learn the functionality of each button. You are not restricted to replaying the last captured clip. Any of the previously captured clips will be found in the Items List of the Library and Tray and may be reopened by dragging them into the InTheAction video display window. 4.2.3 Remote controlling InTheAction Because InTheAction is a tool for use during a training session you shouldn't be a slave to the computer! Now is the time to install the remote control (see Remote controlling Dartfish in the Gettin g fam iliar chapter) and learn to use its features. As has been emphasized several times in this chapter already, all commands covered in this section can be executed by remote control: - Version 6 - © Dartfish. All rights reserved. 64 Dartfish User Guide To use the remote control, its driver must be installed and the infra red receiver connected. How to do for the different types of remote control as well as guidance on using their features is covered in the Gettin g fam iliar w ith Dartfis h chapter. The actual distance at which the remote can be used (max. 20 meters) is dependant on environmental factors and how fresh the batteries are. Batteries are quick to run down if you put the remote in a bag where the buttons get pressed by other contents. Add spare batteries to your Dartfish equipment inventory. 4.2.4 Using a sound trigger Previous topics have indicated that capture using InTheAction can be triggered by clicking the Captu re button and by remote control. There is a third method for triggering capture; a sound trigger that can be configured to react to, for example, a club or bat striking a ball, a starting klaxon or even a voice command. When using voice as a trigger, the sound trigger reacts to the volume, not the quality, of © Dartfish. All rights reserved. - Version 6 - Live capture & instant replay during training 65 the sound. Therefore a voice command will only work if louder than other incidental noise. To use the sound trigger it must be activated and then configured to respond to the correct volume of sound. Activating the sound trigger Before use, the sound trigger must be activated. To do this: 1. Select Tools > Cu s tom ize... from the M en u bar. 2. Select the Rem ote Con trol tab. 3. Tick the box next to sound trigger to activate it. 4. Close the Customize window. It is not necessary to configure the trigger at this stage. Configuring the SoundTrigger 1. From the menus select Tools > Con figu re Sou n dTrigger... Hardware configuration. The input device will generally be set to "Microphone". It is not possible to use the video camera as an input device for sound so your computer will need to be equipped with a built-in or external microphone. Detection configuration. Select the profile that is a closest match to the type of sound used as a trigger then adjust the Sen s itivity slider to an appropriate level; where incidental sounds do not trigger capture but the trigger sound does. Both the hit counter and the Sound Trigger Server Status will help you assess which sounds do and do not trigger. 2. 4.3 Close the Con figu re Sou n dTrigger Properties window. The sound trigger is now active and can be used as a method of triggering InTheAction capture. Comparing clips during training It may be beneficial to compare the last captured clip to a reference clip when working during training. You have the choice to display both clips side by side, blended together or in a picture-in-picture mode. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 66 The steps to compare in InTheAction are to: 4.3.1 1. Define (set) a reference clip. 2. Activate the Com paris on view and capture a clip. The captured clip is automatically compared to the reference clip 3. If needed, synchronize the last captured clip with the reference Setting reference To Set a reference clip, proceed as follows: 1. Load a clip from the Tray or from the L ibrary items into the InTheAction module 2. Click the Set Reference button found below InTheAction playback controls. You can use any other clip already saved on your hard drive as a reference clip. Viewing the reference clip The reference clip can be viewed at any time by clicking on the Referen ce replay button. 4.3.2 Working with comparison view To work with comparison view, click on the Comparison view button on the left edge of the InTheAction module. Comparison view is The screen display will be split in two, the reference clip on the right and on the left the last captured clip. Both clips will be replayed in function of the scenario that you defined (see Defining a replay sequence ). To work with the Compare mode : © Dartfish. All rights reserved. - Version 6 - Live capture & instant replay during training 1. Capture a video clip. 2. At the end of the capture, the clip is automatically displayed next to the reference clip. 3. Use the playback buttons to control the replay 67 To select the comparison layout: Use the following buttons: Split Screen - where the clips will be displayed side-by-side. Basic Blend - both clips will be superimposed on top of each other. Picture-in-Picture - the reference is displayed in the corner of the replay clip. 4.3.3 Synchronizing clips in InTheAction In order to effectively compare two clips, obviously they must be showing comparable activities, for example, you can't compare two divers if one is at a different point in the routine. Synchronizing clips is often unnecessary with InTheAction because a synchronization point is set when capture is triggered. Provided that you always trigger at an obvious moment each time you capture, clips will always be synchronized. To change or set synchronization points 4.4 1. Activate the Replay view (see Capturing and replaying). 2. Find the moment on the clip that is to be the synchronization point. Use the Play/Pau s e and Fram e-by-Fram e buttons to do this. 3. Click 4. Repeat for the reference clip if necessary (use the Referen ce replay button to display the reference clip). . Using drawings in InTheAction The right-hand side of the InTheAction module has a range of drawing tools which can be used to annotate video images, assist with analysis or coaching. The use of these tools is identical to the Analyzer module's drawing tools and is explained in that chapter. 4.4.1 Drawing Library One unique feature of In Th eAction drawing tools is that it is possible to store up to nine sets of drawings in the Draw in g L ibrary. This allows you to reuse drawings from one InTheAction analysis to another. Displaying the Drawing Library 1. To use the drawing library it must first be activated. To do this: 2. Display the Dartfish options (F3 or Tools > Option s menu). - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 68 3. Select the Advan ced topics. 4. From the ITA Settin gs , select the U s e overlay draw in g repos itory option. 5. After applying the change, the Drawing library control will be displayed on the InTheAction module as shown below. Using the Drawing Library 1. Select an overlay from the list (up to nine overlays are possible) 2. Add drawings to the video image 3. As each new video is captured, the drawings from the currently selected overlay will appear on the video image. Remember, at any time drawings can be hidden by clicking the Sh ow /H ide drawing button. The Drawing library is one of the many features that Dartfish have added in response to requests from our users but at the current time, this feature continues to be developed. If the idea of a Draw in g L ibrary is valuable for the way you use Dartfish then you can look forward to further enhancements to this feature in future releases of Dartfish. 4.5 Self coaching with live delay L ive delay provides a completely hands-free way of reviewing video during training which makes it especially useful for self-coaching. It simply delays the display on the computer screen of the images that the camera continuously observes. It's like a mirror but one that waits a predefined number of seconds before showing your reflection. Enough time for the athlete to finish a routine, drill or exercise then assess how he or she performed. For example, a coach might explain adjustments required using the range of InTheAction features explained earlier in this chapter and then leave the athlete to practice, using L ive Delay to confirm the adjustment is being executed correctly. 4.5.1 Live delay settings Before using live delay the camera should be connected and switched to it's camera mode. The InTheAction module is activated and video input set up as described previously (see Preparing InTheAction for use ). To use L ive Delay, you must determine the duration of the movement that you will review and then add 1-2 seconds as a margin. For instance a Golf swing takes 3-4 seconds, it might take a further 5 seconds to get to a position to view the computer display - you would then set an 11 second live delay (2+4+5). Setting the amount of delay 1. From InTheAction's Recordin g Option s ch an ge th e live delay valu e. The largest amount of seconds you can set is related to the amount of available RAM memory of your © Dartfish. All rights reserved. - Version 6 - Live capture & instant replay during training 69 computer. 2. Click on the Live Delay view button. 3. Press F11 on your keyboard to have a full screen view (press F11 again to come back to normal view). That's it! No button presses, no files recorded, no comparison, no pause or replay. Just a simple tool to help with self coaching. Using live delay doesn't stop the use of other InTheAction features. As soon as the capture button is pressed/clicked, capture begins according to the pre-record and duration settings and replay commences straight away. However, to trigger the capture, always refer to the live action and not to what you seen on the screen. 4.6 Next steps InTheAction allows you to review and compare performance while training takes place but to review these performances at a later date you should learn how to load, synchronize and compare clips in the Analyzer module. The Analyzer module will also allow you to publish your clips into a media book; a remote coaching tool complete with audio and text guidance (read the chapter on the Analyzer). - Version 6 - © Dartfish. All rights reserved. Chapter V Analyzing Performance 72 5 Dartfish User Guide Analyzing Performance Dartfish's Analyzer module is packed full of features to help observation and understanding of sport. This chapter guides you through these allowing you to: Compare video. Up to 4 clips can be compared side by side and 2 clips can be blended. It is quick to synchronize clips to make the cation contained comparable. You are not limited to just four clips in your analysis as a project can contain multiple analyses in its Storyboard. Annotate video A collection of drawing and text tools help enhance observation, make measurements of distance, angles and time and add text to video clips. Tools exist to enhance the effectiveness of drawings such as automatic tracking and fading them in and out at relevant positions in the vide clip. Text or audio comments can added to an analysis to create a lasting record of your analysis and to save time, previous comments can be imported from previous analyses. Identify important moments Key Pos ition s can be identified and drawings and comments added to them. Each key position can also be a synchronization point, allowing more than one synchronization in each comparison. © Dartfish. All rights reserved. - Version 6 - Analyzing Performance 5.1 73 Analyzer workspace The An alyzer workspace is illustrated below: Its main constituents are: Video Screen - to display the clip(s). Tim elin e - (underneath the screen), to control the playhead position and set the cu e in / ou t points to define the playable part of the video. Play con trols - (underneath the timeline) to control the video playback. Dis play m ode - (top-left) to change the screen display. You can select among Sin gles creen , Split-s creen , Blen d and M os aic modes. The A, B, C and D buttons show/hide a clip. In split-screen modes, they are used to select between up to four clips to display simultaneously. Im age E n h an cem en t tools - (underneath the C, D buttons) to zoom in/out or flip the images. Draw in g tools - (on the right) to draw on the video. Storyboard - (underneath the play controls) contains the different analysis of an An alyzer project. Pu blis h in g - (on the right of the storyboard) to publish your analysis on different media (CD, e-mail, printer, Internet) or to create a movie of the Storyboard. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 74 N otes - (at the bottom) to add written and audio comments. To see this area it may be necessary to resize the Analyzer views area. This is done by click and dragging its top border using the mouse shape shown in the following illustration. You can switch between different views using the following tabs The Data Graph is used to display external data streams (such as the heartrate, speeds, etc.) captured by external devices such as radar, heartrate monitors, force platforms etc. Such streams are synchronized with the video. More information can be downloaded on http://www.dartfish.com/downloads. Read the remainder of this chapter to learn about An alyzer functions and about the other views. 5.2 An analyzer project - the Storyboard The Storyboard can contain multiple analyses that constitute an An alyzer Project. Each item in the Storyboard corresponds to one analysis. For example, you could analyse swings of a students captured during a training session, one from the front, one from the side and one from the front compared to a reference swing, as illustrated below. Each analysis may include drawings and audio commentary. All this is saved in your An alyzer Project along with the videos. Your project can be: 5.2.1 1. Re-opened later to modify/add analysis elements (e.g. add a fourth swing, modify a drawing, etc.) 2. Publish to different destinations (e-mail, CD, printer, internet) to be handled out to your student/athlete (see Publishing Analysis). Loading clips Clips can be loaded as multiple clips within a single analysis or as a new analysis. To load a clips into an analysis 1. Activate a vacant video display screen A, B, C or D in Sin gle-s creen m ode or display the required number video display screens in Split-s creen m ode. © Dartfish. All rights reserved. - Version 6 - Analyzing Performance 2. 75 Double click each clip in the Item s L is t or the Tray of the L ibrary. You can also drag & drop a clip onto any video display screen. This offers greater flexibility over which video display is used. This method can also be used to replace a previously loaded clip. To add a new analysis (i.e. a new Story board item) Drag & drop a video from the Item s L is t or Tray onto a vacant position on the storyboard. To replace a Storyboard item You can replace the video clip of a Storyboard item with another one. To do this, drag & drop the new clip on top of the old one. To delete an analysis (i.e. delete a Story board item) Right-click on the Storyboard item and select Delete from the context menu. Starting a new project ( File>N ew from the menu bar) will empty all items from the Storyboard. 5.2.2 Playing clips Once a clip is loaded you have the ability to control the playback (play/pause, stop, frameby-frame, etc.). This can be done by using the playback controls buttons and the timeline underneath the video screen. Read the Video Playback section in the Gettin g fam iliar chapter to learn more. The functions of the buttons are the same as for the Player module except for Play n ext/ previou s clip and the Repeat m ode which applies to items of the Storyboard rather than items of the Tray. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 76 5.2.3 Saving an analyzer project Select File>Save (or File>Save As ...) from the M en u bar to save a project. An alyzer projects can be identified by the following icon. - Analyzer project If a project is saved in a M on itored folder of your L ibrary (see section Defining your library in the Library chapter), it will be displayed in the Item s L is t. To open a saved project Double-click on the project in the Item s L is t Select File>Open from the M en u bar. To start a new project Select File>N ew from the M en u Bar. Starting a new project empties the Storyboard. 5.3 Analyze a performance In this section, you will learn to use the different tools to analyse a performance: Image transformation tools - such as zoom and flip horizontal or vertical (see Enhancing images). Drawing tools - qualitative tools to highlight details and quantitative tools to extract statistics out of the video (see Drawing on the video). Comments - audio and written comments (see Adding comments). Key positions - brake down a movement and analyse its key positions separately (see Analyzing key positions). 5.3.1 Enhancing images Dartfish's An alyzer allows you to zoom in or out on an image to better see the details of a particular moment. There are many ways to zoom in/out: 1. Use the M axim ize video button at the bottom of the An alyzer screen (3rd button in the illustration below). When selected, the video is enlarged to occupy the available height of the display area (to do this the left and right edges of the video may be hidden). 2. Use the Dis play video fu lls creen button (right-most above). The video is displayed in full screen (press [ESC] on your keyboard to return to normal view). 3. Click on the Zoom Tool button, position the mouse cursor over the part of the picture that you want to zoom on and left click (right click to zoom out). © Dartfish. All rights reserved. - Version 6 - Analyzing Performance 4. 77 Click anywhere in the An alyzer's screen and use your mouse scroll-wheel. The image will zoom towards the location pointed by your mouse cursor. Once the image has been zoomed in, you can move the zoom focus in two ways: 1. Click on the M ove Tool button and drag the mouse cursor until the screen displays the part of the image you want the zoom to focus on. 2. Click and drag using the mouse wheel. You can play the clip(s) once it is zoomed. The zoom perspective is maintained. Zoom options Clicking on the Zoom Tool button displays options at the top of the An alyzer's screen: From left to right, the buttons give access to the following function: Res et Zoom - resets the zoom factor to 100% Zoom In - each click increases the zoom factor by 20% Zoom Ou t - each click decreases the zoom factor by 20% Zoom Factor - set the zoom factor by selecting it from a predefined list Qu ick M agn ify - changes the mouse cursor to a magnifier to quickly point to details. You can change the zoom factor inside the Qu ick m agn ify tool by using your wheel mouse. [shift] + wheel mouse will modify the radius of the magnifier. Flip a Clip Horizontally or Vertically To get a new perspective on a clip, you can flip it horizontally or vertically. To do this, click the Flip H orizon tal or Flip Vertical bu tton . The button appears as "pushed". You can flip the image horizontally and vertically at the same time. 5.3.2 Drawing on the video Dartfish allows you to draw objects and add text on top of a clip's images. Use qualitative drawings (e.g. lines, circles, rectangles, etc.) to highlight details. Quantitative tools (angles, measurements, etc.) can be used to extract statistics from the video. The Drawing Toolbar Use the following toolbar to draw and write text on the video. Draw in g m an agem en t tools - to select, show/hide, delete, and undo/redo drawings. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 78 Video Draw in g vs . Screen Draw in g - two modes to draw on clips. 1. In the Video Draw in g mode, your drawings are associated with the selected clip. 2. Use the Screen Draw in g mode to draw across the An alyzer's screen (see Comparing performances). Draw in g tools - the various tools to draw on the video. Most of these tools are self-explained. Read the remaining of this section to learn about the more advanced tools. The tiny arrow on the lower-right of a drawing tool indicates that other tools of the same type can be accessed by a mouse right-click, as illustrated below: 5.3.2.1 Adding and modifying drawings To add a drawing 1. Display the frame of video to which you wish to add drawn objects and/or text. To do this, you can drag the playhead and use the frame-by-frame buttons. 2. Select a drawing tool 3. Position the mouse cursor on the image at the point where you want to start drawing 4. Left click, hold and move the mouse to the end point 5. Release the mouse button Although you are drawing on a single frame of video, the drawings will be displayed for the entire clip. Use the key position analysis (see Analyzing key positions) if you want to apply different drawings to different frames. It is also possible to fade drawings in and out so that they only appear for part of the clip (see Fading drawings in and out). Holding down the [shift] key "constrains" drawing, e.g. to draw a horizontal line, a square, a circle, a 90 degrees angle, etc... By default, selecting a drawing tool once let you draw a single object. If you would like to draw the same object many times in a row (e.g. multiple lines), select the currently selected tool a second time. A vertical gray mark appears in the tool and indicates that you © Dartfish. All rights reserved. - Version 6 - Analyzing Performance 79 are in a "repeat drawing" mode. To leave this mode, click the selected tool a third time or select another one. To modify a drawing 1. Click the Selection button (top-left of the drawing toolbar). 2. Click on the object you wish to select. White handles appear on the object. If you wish to select multiple objects, hold down the [Ctrl] key as you select additional objects. 3. Once the object(s) is selected, you can: Drag a handle to change the size or shape of the object. Click and drag the selected object to another location. To delete drawings Use the Delete All button Select a drawing and press the [delete] key or use the Delete button Use the U n do/Redo buttons to go back to the previous state 5.3.2.2 Drawing properties You can change the thickness, color, opacity, size and other properties of the drawings. The draw in g properties bar is displayed at the top-right of the An alyzer screen To modify a property: 1. Click on the drawing to select it. 2. Click the button that corresponds to the property you want to modify. 3. Select the different value/color/font. The 1 , 2 and 3 buttons correspond to properties pres ets . Left-click on these buttons to apply a preset. To change a preset: 1. Draw an object - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 80 5.3.2.3 2. Modify its properties 3. Right-click one of the 1 , 2 or 3 buttons. Clone rectangle The Clon e rectan gle tool allows you to "clone" and magnify an area of the image. Play the video to visualize both the magnified area and the performance in its whole (picture-inpicture effect). To use this tool, proceed as follows: 1. Select the Clon e Rectan gle drawing tool 2. Click, hold and move the mouse cursor to draw a rectangle around the area you want to clone. 3. Click and drag the cloned area to the location you want 4. Use the white handles to magnify the cloned area 5. Click anywhere in the image (except the drawing itself) to deselect the cloned area. For best result, use a tripod and leave the camera fixed (no zoom, pan or tilt). If the camera moves, you can still use this effect but in conjunction with the au tom atic trackin g function (see Tracking objects automatically). 5.3.2.4 Picture You can import a picture and overlay it on top of the video. You can use for example this function to insert your logo or to compare a key position to a reference image. © Dartfish. All rights reserved. - Version 6 - Analyzing Performance 81 To add a picture 1. Select the Im age drawing tool. The Open Im age dialog opens. 2. Browse for the image on your disk and click on the Open button. The image overlays on top of the video screen. You can change the size of the picture by dragging the white handles. Hold down the [shift] key while doing this operation to constrain the proportion of the image. You can also click and drag the image to a different location. If the image width is larger than 360 pixels, it will automatically be resized to this value. If you load an image in Screen Draw in g mode (see Drawing on the video), it will always be overlayed at the same location in the video. Use this, for example, if you want your logo to be displayed always at the same location. 5.3.2.5 Measuring angles The image below illustrates the An gle tool. To add an angle: 1. Right-click on the Tim e button and select An gle from the context menu. 2. Position the cursor on the image exactly where you want the corner of the angle to be. 3. Left-click, hold and move the mouse cursor (in the image above, click on the club head and move horizontally). A line draws as you move the mouse. 4. When the line extends to where you want the angle to open, release the mouse button. 5. Move the cursor up or down to create the desired angle. The number of degrees of the - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 82 angle is shown as you move the mouse. 6. Click the mouse when the angle is the desired width. You can modify the line thickness, colors and font (see Drawings properties). Hold down the [shift] key while drawing to constrain the angle to 0, 45, 90, ... degrees. 5.3.2.6 Measuring distances The image below illustrates the Dis tan ce tool. Distances are only precise in a plane perpendicular to the camera. You first have to calibrate this plane by defining a reference distance. To do this, put an object of known length at the position where the movement will be performed (the width of the mat in the above example). To measure distances, proceed as follows: 1. Right-click on the Tim e button and select Dis tan ce from the context menu. 2. Click, hold and move the mouse cursor to draw the reference distance (the one with the dashed line in the image above) 3. Right-click on the reference distance and select Set as referen ce... from the context menu. The following dialog opens © Dartfish. All rights reserved. - Version 6 - Analyzing Performance 4. Enter the size of the reference object. 5. Select the Dis tan ce tool again and draw the distance (vertical line in the example above). It will be computed based on the line length and the reference value. 83 The measurement precision relies on many factors such as the distance between the camera and the performer, the camera zooming factor, the precision of the perpendicularity between the camera axes and the plane in which the movement is performed, etc... Try to be as precise as possible when setting the reference distance. For example, use a well defined and distinct marker on the floor and use zoom tools to enlarge the image when setting the reference distance. 5.3.2.7 Using stopwatches Dartfish allows you to use multiple stopwatches to estimate the duration of a performance, to measure time in different sections of a performance/race, to estimate/compare different time/speeds. The stopwatch displays the time in minutes:seconds.frames (mm:ss.fff). Its precision is function of the number of frames/sec, i.e 2'' of a second in Europe (corresponding to 50 frames/sec in PAL video) or 1.66'' of a second in North America (NTSC video, 60 frames/sec). To add a stopwatch 1. Select the Tim e drawing tool 2. Click anywhere in the image to insert a stopwatch. Use the drawings properties (see Drawings properties) to modify the color and font. The stopwatch displays the current position of the playhead at the moment it is inserted in the image. To reset a stopwatch 1. Right-click on a stopwatch (that has already been placed in the image) 2. Select Set tim ecode to 0 0 :0 0 in the context menu To start/stop counting You can start and stop counting in a section of a performance/race. For example, you may - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 84 want to compute the time from gate 1 to gate 7 in a giant slalom to compare performances in this particular section. To do this: 1. Position the playhead at the position you want to start counting 2. Set tim ecode to 0 0 :0 0 (optional) 3. Right-click on a stopwatch and select Start cou n tin g 4. Position the playhead to the end of the section 5. Right-click on the stopwatch and select Stop cou n tin g You can change the start and stop position by setting them to a new position. To disable this feature, simply uncheck the Start and Stop cou n tin g from the drawing context menu. 5.3.2.8 Tracking objects manually You can draw trajectories by manually tracking object in the video clip. For example, you could draw the swing plane as illustrated below. The yellow curve represents the up-swing and the orange one, the down-swing. Dartfish creates the trajectory by joining selected points while smoothing the curve in between. The trajectory redraws as the video plays (see image on the right). To draw a curve, use the Splin e tool and proceed as follows: 1. Right-click on the L in e button and select Splin e from the context menu. 2. Position the playhead at the beginning of the performance 3. Click on the object you want to track. A white square indicates the first point of the curve. 4. Use the [ctrl] left/right arrow keys to move the playhead forward a few frames 5. Repeat steps 2 and 3 as many times as needed. 6. Right-click and select Fin is h from the context menu to terminate the curve. To modify the trajectory, select it and move any point you have defined. The curve modifies accordingly. © Dartfish. All rights reserved. - Version 6 - Analyzing Performance 85 The trajectory draws as illustrated above only if it is deselected (white squares not visible). To do this, click anywhere in the image but on the curve itself. The curve can be drawn on a single frame. In this case, no tracking takes place. The number of points you have to define varies according to the speed of the object. The faster the object, the more points you have to add to get a smooth curve. 5.3.2.9 Tracking objects automatically Dartfish offers you a powerful function: the au tom atic trackin g (available in the Team Pro and ProSu ite editions). The principle is the same as for the manual tracking (see previous section) except that the computer automatically tracks and optionally draws the trajectory of an object(s). The au tom atic trackin g function can be used with most of the drawing tools: e.g. with the rectan gle, oval, clon e rectan gle to highlight the evolution of an object/ performer throughout the video. e.g. with the m arker tool, to automatically draw the trajectory of a well defined feature. with the s plin e tool (see Tracking objects manually) to visualize the evolution of the shape of an object/body over time . In this case, each point of the curve is tracked separately. with the an gle (see Measuring angles) and dis tan ce (see Measuring distances) tools to measure the evolution of such data. with the Data table (see Using data tables) to automatically extract statistics from the image and store them in a spreadsheet. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 86 Tracking is a complex process; for Dartfish to successfully track objects they must remain clear and visible. You can help it by tracking clear features with a high contrast. Try to use markers as illustrated in the pictures above. Use your camera's focus and exposure features to avoid blurring of moving objects. To activate the automatic tracking 1. Position the playhead at the beginning of the performance 2. Select a drawing tool and draw on the video 3. Right-click on the drawn object and select Trackin g in the context menu 4. Select the object speed from the context submenu (this defines how far from the last position Dartfish will search the video image for similarly colored/shaped objects). 5. Click the image to deselect the object Using the automatic tracking To start tracking, simply play the video. The drawing color changes to green indicating that Dartfish has started to track the object. At any moment, you can pause playing: If you observe that the tracking is "lost" (e.g. when the object gets occluded). In this case, manually reposition the drawing onto the tracked object and continue playing. If the object disappears from the field of view. In this case, right-click on the drawing and select Su s pen d trackin g from the context menu. Dartfish stops tracking from this position (the drawing color changes to red). To show the trajectory Once you have activated automatic tracking (see above), right-click on the drawing and select Sh ow trajectory from the context menu. The trajectory progressively draws as the video plays. 5.3.2.10 Fading drawings in and out In most cases, drawings are valid only for a small portion of a movement. You can use the Fade in /ou t function to display a drawing only during such a portion. To do this, proceed as follows: 1. Position the playhead at the desired position. 2. Draw an object on the video 3. Step a few frames backward (using the [ctrl] + left and right arrows) 4. Right-click on the object and select Fade in from the context menu. 5. Select how quickly the drawing appears from the context submenu. 6. Step a few frames forward. © Dartfish. All rights reserved. - Version 6 - Analyzing Performance 87 7. Repeat the steps 4. and 5. to set the Fade ou t. 8. Deselect the drawing and play the video from the beginning. The drawing will only show in the defined portion. Use this function if you want to publish a new video that contains drawings that fade in/ out. If you want to analyse key moments of a performance we recommend you use the key pos ition s (see Analyzing key positions) which can be printed or published in an interactive Dartfish M ediabook. 5.3.2.11 Using data tables The Data Table drawing tool enables you to collect time-dependent data related to the action in your video. For example, at different time instances you can manually enter the distance an athlete has run so far, just as you would in an Excel spreadsheet. Then, the data table tool can compute (and display) automatically the average overall speed or the interval speed of the athlete. It is also possible to link another drawing tool such as an angle or a measuring tool to a column of a data table, to display and store the evolution of the corresponding quantity (angle/length) over time. In the following image you can see a data table containing heights inferred by a measurement drawing. An advanced feature is the option to track an object in the video automatically and to display the corresponding positional data in a data table. Finally, you can export the collected data in Excel format for further processing and analysis. A comprehensive guide on how to use this drawing tool can be downloaded on the Dartfish website (visit http://www.dartfish.com/downloads). 5.3.3 Adding comments The An alyzer allows you to "produce" enriched multimedia content. It gives you the ability to combine your coaching expertise with images to generate powerful presentations (see Publish Analysis) that you can share with your athletes/students for use with their daily practice. You already learned how to add drawings on the video to highlight details or to extract statistics from the images (see Drawing on the video). In this section you will learn how to add verbal and written comments which can be used to analyze: 1. a performance in its whole ( global comment). In this case, use the lower part of the Storyboard tab. 2. key positions (or key moments) of a performance ( key pos ition s pecific comment). In this case, use the lower part of the Key pos ition s tab (see Analyzing key positions). - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 88 5.3.3.1 Written comments To add written comments, simply enter your text in the N otes box, as illustrated below: This box is located on the lower-left of the An alyzer module (in the Storyboard or Key pos ition s tabs). 5.3.3.2 Audio commentary To add an audio commentary: 1. Select the audio recording device from the drop-down list of the Recordin g Device pane. This pane is located on the lower-right of the An alyzer module (in the Storyboard or Key pos ition s tabs). Use the microphone of your camera to record audio (the camera has to be connected to the computer through the Firewire cable). Alternatively, you can use a microphone and select your sound card as the audio device. 2. If needed select the input. If you have plugged a microphone in your sound card, select "Microphone". 3. Click on the Record button it will begin to record your audio input. 4. Click on Stop when you are finished. To play back the recorded audio comment, use the Play button . Recording a new audio comment overwrites the last recorded one. To be more fluent and comfortable recording an audio comment, you can first write your comment in the N otes box and read it simultaneously as you record audio. 5.3.4 Analyzing key positions Key position analysis allows you to break down a movement and to analyze its important moments by using drawings, audio and written comments. Key positions allow you to display specific moments quickly. You'll also have the ability to publish the key positions in two formats: 1. The M ediabook - an interactive multimedia analysis that you can save to a CD-ROM, © Dartfish. All rights reserved. - Version 6 - Analyzing Performance 89 send via e-mail, or publish on the Internet (see Producing mediabooks). 2. A printed report - the collection of key position images printed in different layouts (see Creating still images). To use key positions analysis, select the corresponding tab in the lower part of the An alyzer . 5.3.4.1 Adding key positions To add a key position, proceed as follows: 1. Move the Playh ead to the position you wish to highlight. Use the Fram e buttons (or the [ctrl] left and right arrows to refine the position). 2. Click on the Add key pos ition button. A new key position appears with its default label underneath. To add other key positions, repeat the two steps above. Key positions can be added in any order. Say you analyze a long jump, you can first create the key position of the landing followed by the one when the jumper hits the board. The default labels are integers (1, 2, 3, etc.) Try to make a consistent use of the labels. You will see in section Synchronizing video clips that clips can be easily synchronized by matching key positions with the same label. Read next section to learn how to edit the label. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 90 5.3.4.2 Editing key positions To edit one key position, select it by clicking the corresponding thumbnail... ... and do one of the following operations: rename the label - type the new label in the L abel box (e.g. back s w in g in the illustration above) change the video position - use the left and right arrows next to the Pos ition box. change the order - key position do not need to be listed in a chronological order. You can change the order by using the M ove th e keypos ition backw ard/forw ard buttons. The key positions will be published in the order you defined. delete - use the Delete key pos ition button or right-click on a thumbnail and select Delete from the context menu You can delete all key positions by clicking on the Dis play Key Pos ition s Option s button and selecting Delete All Key Pos ition s . 5.3.4.3 Analyzing a key position To analyze a key position: 1. Select the key position by clicking on the corresponding thumbnail (or create a new one, see Adding key positions). The selected key position is highlighted and the screen displays the corresponding video position ( top in the illustration below). 2. Add your analysis by using: drawings (see Drawing on the video) written comments (see Written comments) audio comments (see Audio commentary) © Dartfish. All rights reserved. - Version 6 - Analyzing Performance 91 Your analysis is automatically attached to the selected key position and saved with the clip. If you add a global drawing (when the Storyboard view is selected), all new key positions will "inherit" this drawing. This can be used if you want a drawing to be positioned exactly at the same place in all key positions. You still can delete the drawing in a particular key position if not needed. 5.3.4.4 Importing key positions You can import an analysis that was performed on a clip and use it as a basis for a new one. Your library can thus contain a set of "reference" clips that you already have analysed. Select the one that could best be used to automatically create the key positions and import the existing annotations. Once imported, you'll only have to slightly adapt the video position of the key positions and edit the drawings/text. To import key positions: 1. Load the clip to analyze. 2. Position the playhead (e.g. at the impact of the golf club with the ball). 3. Find a "reference" clip in your library. 4. If needed, switch to the Key Pos ition s view. 5. Drag and drop the reference clip from the Item s L is t onto the key positions (see the paragraph below to learn about a different method of loading the reference clip). The In s ert Key Pos ition s dialog opens. 6. The list of key positions of the reference clip is contained in a drop-down list. Select the one that best synchronizes to the current playhead position (e.g. impact). Another way to select the reference clip: 1. Select Add Key Pos ition s Au tom atically... from the key positions options 2. In the In s ert Key Pos ition s dialog, select Im port key pos ition s from an oth er clip. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 92 3. If the reference clip is already loaded in the An alyzer, it will be listed in the 2nd drop down list (see illustration above). If it is not listed, you can use the Brow s e for clip link and locate the reference clip on your hard disk. To edit key positions: Simply navigate through the imported key positions by clicking them. If needed, modify their position by using the M ove th e key pos ition backw ard/forw ard in tim e buttons: You may have to edit imported drawings and comments (see Adding and modifying drawings). 5.3.4.5 Adding key positions at a fixed interval You can automatically create key positions at a fixed interval. To do this: 1. Position the playhead where the first key position will be added. 2. From the Key Pos ition s Option s , select Add Key Pos ition s Au tom atically... 3. In the In s ert Key Pos ition s dialog, select Add key pos ition s at fixed in tervals , and set the interval (as a fraction of a second) The minimum interval is 0.1 sec. 5.4 Comparing performances A performance can be analyzed by comparing it to another one, for example to see how an athlete evolves over time, or to a "reference" to highlight how a movement should be performed. You can also analyse a performance viewed from different angles at the same time. © Dartfish. All rights reserved. - Version 6 - Analyzing Performance 93 Performances can be compared in Split-s creen or in Blen d mode (overlayed on top of each other). Most of the tools described in section Analyze a performance can be used when comparing performances. 5.4.1 Loading multiple clips You can analyze clips individually or in groups of up to 4 clips at a time. The clip selection buttons - A, B, C and D - correspond to the multiple clips that you can load into the An alyzer. In other words, you can compare a performance (loaded in A) with up to 3 other performances in the following ways: separately - A vs. B, A vs. C or A vs. D (2-way split, or blend mode). simultaneously - A vs. B vs. C (3-way split) or A vs. B vs. C vs. D (4-way split). To load a clip: 1. Click on one of the selection buttons (A, B, C or D). The button appears to be pushed in. 2. Drag & drop (or double-click) the clip from the Item s L is t (or the Tray) onto the An alyzer 's screen. The clip's first frame is displayed, and its name appears in the timeline underneath the screen. To load additional clips, repeat step 2 and 3 above but make sure to select a letter for which no clip has been already loaded. To change a clip (A, B, C or D) Drag & drop the new clip from the Item s L is t to the desired A, B, C or D area. Double-clicking on a new clip will not replace an existing clip but will create a new Storyboard item. Use the drag & drop method to change a clip. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 94 5.4.2 Display modes The display mode of each Storyboard item can be changed to Split-Screen or Blen d to compare performances side-by-side or overlayed on top of each other. To change the display mode: 1. Select the storyboard item you wish to analyse in split-screen or in blend mode. 2. Activate the desired mode: Split-Screen m ode, or Blen d m ode The storyboard item display changes accordingly. In the illustration below, the second Storyboard item has been selected and the split-screen mode activated. 3. Select the clips to analyze by clicking the corresponding buttons - A, B, C or D. The buttons appear as "pushed". To de-select a clip, click on the corresponding button. To load or change a clip in split-screen or blend modes Split-Screen mode: drag & drop the new clip from the Item s L is t onto the appropriate screen area (A, B, C, or D). If needed, click on the A, B, C or D buttons first. Blen d mode: 5.4.3 1. Click the corresponding clip button - A, B, C or D. The letter is highlighted in white. 2. Drag & drop the new clip in the An alyzer screen. Synchronizing video clips To make the images in the different clips comparable, you need to synchronize their action so that you are comparing relatively similar action within the performances. You can synchronize video clips by using the key positions (see next section) or by using the timeline(s). Method A 1. Load two clips in split-screen (see sections Loading multiple clips and Display modes) 2. Click anywhere in the clip displayed on the left of the screen (most likely clip A). A blue timeline shows underneath the screen. Note that timelines are color-coded according to the display screen; blue corresponds to letter A. 3. Drag the Playh ead to the position where the clip should be synchronized (e.g. at the impact) 4. Click the clip on the right of the screen (most likely clip B). A yellow timeline replaces the blue one. 5. Click and drag the yellow timeline forward or backward (NOT the playhead) until the two clips are synchronized (e.g. when both clips are at the impact). © Dartfish. All rights reserved. - Version 6 - Analyzing Performance 95 Use the [shift] + [left] (or [shift] + [right]) arrow to fine tune the synchronization. This moves the timeline one frame backward or forward. To play the synchronized clips, click on the Stop button to move the Playh ead to the beginning of the play range and click the Play button. Method B You can use the Tim elin e view to synchronize clips. Click on the corresponding tab to display this view. The synchronization process is the same as described above except that you do not need to click a clip to select the blue or yellow timeline. You can directly click on a timeline to select it. This view also allows for quick re-synchronization. Simply move the playhead to a new position and adjust the timelines to re-synchronize at the new position. 5.4.4 Synchronizing at key postions If you have added key positions to the clip(s) (see Adding key positions), you can synchronize performances at every key position for which the labels match. For example, if you consistently use the label "impact" when the club hits the ball and "top" for the position that corresponds to the end of the back swing, it will be very simple to resynchronize two clips at "impact" or at "top". You can synchronize clips by matching key positions with the same label. To do this: 1. Load two clips in split-screen. 2. Switch to the Key Pos ition s view. Say that both clips contain a key position with the label "impact" at the position where the club hits the ball. Labels must exactly match (see Editing key positions to find out how to edit key position labels). 3. Double-click on the key postion "impact". This method allows very fast re-synchronization at every matching key position. If you add key positions to a clip by importing them from a reference clip (see Importing key positions), it will be very easy to synchronize both clips because labels are imported from the reference clip and so exactly match. If the clips contain multiple key positions, you can synchronize them at a particular position by a double click and navigate through the other key positions by a single-click and observe the relative position of the performers. For example, if you have a key position at every gate of a giant slalom it will be easy to see the distance gained or lost by a skier between each gate. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 96 5.4.5 Setting default synchronization In the previous topics in this section you have learned that it is possible to synchronize clips at various positions. It is also possible to set a default synchronization position. This is a single Key Pos ition at which clips will automatically be synchronized when the clips are loaded into Analyzer's s plit-s creen mode. This saves time resynchronizing clips that are repeatedly compared. To set default synchronization 5.4.6 1. Add a key position at the chosen video position. 2. Right-click while pointing at the key position and select s et as defau lt s yn ch ron ization from the quick menu. 3. The default synchronization key position which shows the is marked with a yellow dot as shown below. Analyzing in split-screen mode Analyzing in split-screen is very similar to analyzing in single-screen. However, there are minor differences that you should know about. Drawings Select the appropriate drawing mode (in the drawing toolbar) Video Draw in g - drawings will be applied to either clip A, B, C or D. Simply select a drawing tool and apply it on A, B, C or D. Screen Draw in g - drawings are applied onto the whole An alyzer screen. This means that the drawings can go across the A, B, C or D boundaries. In the example below, the Clon e Rectan gle drawing tool and the Screen Draw in g mode have been used. © Dartfish. All rights reserved. - Version 6 - Analyzing Performance 97 Zoom in/out You can apply the Zoom Tool in any of the A, B, C or D clips. Simply click on the corresponding area to zoom it. Flip horizontal or vertical To use this function (see Enhancing images) in split-screen, you first have to select the video (A, B, C, or D) by clicking on the corresponding area. The timeline changes to the A, B, C or D color. Then, use the Flip H orizon tal or Flip Vertical buttons to apply the effect. 5.5 Key position mosaic Analyzer's M os aic view offers a method of displaying Key Position images on the video display screen. This offers the following benefits: Have an at-a-glance view of a performance key moments Analyse a performance in between key positions. Key Positions can be displayed beside the video image as it plays. In the example below the video is displayed in the middle of two key positions. Playing the video shows how the performer reached the key position on the right starting from the one on the left. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 98 Analyzer's drawing tools can be used to annotate and illustrate the M os aic. 5.5.1 Activating the mosaic Activate the Mosaic by clicking on the M os aic button towards the top left of the Analyzer module. Once activated, there are several Mosaic layouts to choose from. Click the N ext/previou s M os aic L ayou t button to navigate between layouts. The Mosaic mode is used in conjunction with the other Analyzer display modes; Sin gle/Splits creen and Blen d (see display modes in the Comparing performances topic) . Different mosaic content will be displayed depending on which one of these is selected. Not all Mosaic layouts include the video clip. If there are more key positions than can be displayed with the selected Mosaic layout, the key positions will display dynamically, this means that as the Playh ead moves along the Tim elin e, the closest set of key positions to the current video position will be displayed. 5.5.2 Drawing on the mosaic The Drawing tools can be used to annotate the Mosaic, however it is important to note that although the Video Draw in g tools may be used to draw on the video clip, only the Screen Draw in g tools may be used to draw on the Key Position images. Drawings extending from the video to a key position or from one key position to another must also be made with the Screen Draw in g tools. To learn more about using drawing tools see Drawing on the video and Analyzing in splitscreen mode. Saving Mosaic Images The Mosaic layout and any drawings that it contains can be saved as a still image (BMP or JPEG) using the Sn aps h ot button found immediately below the video display . 5.6 Next steps The analysis contained in the Storyboard can be published in 3 formats: 1. The M ediabook - an interactive multimedia analysis that you can save to a CD-ROM, send via e-mail, or publish on the Internet 2. A printed report - the collection of key position images which can be printed in different layout 3. A new video clip © Dartfish.

Chapter VI Dartfish outputs publishing & sharing 102 6 Dartfish User Guide Dartfish outputs - publishing & sharing Although this chapter is primarily concerned about how to publish video based resources, it is worth considering the full range of possible outputs: The Player (Save Movie function) can create video clips trimmed from longer clips. It can also create still images (snapshots) based on the current frame of video. The An alyzer can also create snapshots. Key pos ition s too can be turned into still images and printed or saved. Here the Save M ovie function is more advanced allowing you to render the contents of the storyboard as movie complete with any drawings added or comparisons made. All Analyzer features can be packaged up into a Mediabook. In this format, others can benefit from your complete analysis. The complete Storyboard can also be shared with other Dartfish users. Users of the Pro edition also have an An alys is Recorder; this creates a movie showing screen and voice recording of all the actions you go through to explain your analysis. The M ediabook is an output from the An alyzer but it is also able to print its key pos ition s as still images complete with notes and drawing annotations. Strom otion (Pro and TeamPro only) outputs a movie or a panoramic still image made from each frame of the movie and cloned objects superimposed. Sim u lCam (Pro and TeamPro only) creates a movie by overlaying two videos and matching the backgrounds. Taggin g (TeamPro) users can output match video comprised of separate video files. Video clips can also be created from events but events can also be exported to the An alyzer Storyboard where the full range of An alyzer producing, publishing and sharing options becomes available. The events list itself can be exported and published either independently or with the video. The tagging player has the same snapshot tool as the Player. In Th eAction has no direct outputs but when video recorded by InTheAction is loaded into the Analyzer, drawings added and the key position created at the trigger point are retained. 6.1 Destinations The range of destinations for shared and published outputs varies depending on the type of output and the software edition. Below there is a summary of the options that require further explanation. © Dartfish. All rights reserved. - Version 6 - Dartfish outputs - publishing & sharing 103 Dartfish TV Dartfis h TV is an online content platform for the sharing of video clips and An alyzer Storyboards . Where video clips have key positions or tagged events (TeamPro edition) this information can also be uploaded and shared. It is even possible to attach other files such as spreadsheets, images or documents to be associated with video content. Your profile defines what access you have to specific files so Dartfish TV is both a convenient and secure way to share video and analysis. Dartfish TV is a subscription service for those who want to upload content but there is also publicly accessible content available to view or download. See www.dartfish.tv - Version 6 - © Dartfish. All rights reserved. 104 Dartfish User Guide My Computer This allows you to copy files or publish outputs not only to folders on your own hard drive but also all locations accessible from it. These include network drives, external hard drives, memory sticks etc. Email Compresses video clips and attaches them to an email using your default email software. The Dartclip file containing category/value information for each file is included. Dartfish is only able to attach to email software like Outlook and Outlook Express. If you use web based email like Hotmail, GoogleMail etc then you should convert the videos you want to send (see Converting video clips) and attach them using the email software or website. Recordable CD/DVD This choice of destination "burns" video files to recordable CD-R, CD-RW or data DVD disks including metadata. Burning to DVD does not create DVDs that will play on a DVD player but a data DVD holds a lot more data than a CD: © Dartfish. All rights reserved. - Version 6 - Dartfish outputs - publishing & sharing 105 CD - 700Mb approx DVD - 4.7Gb Double layer DVD - 8.5Gb Enhanced CD/DVD A second method of burning video clips to CD or DVD is to produce an Enhanced CD/DVD. This has the following advantages: The resulting CD autoruns - the user simply has to insert it into their computer's CD drive. Customizable interface which can be personalized with your own contact details (see image below). Comments can be included to describe explain the content of video clips. FTP This sharing option is used to send (ftp) files to an internet destination. To do so, you will need to create an FTP Profile using the connection information for your FTP server. This information can be provided by your network administrator or the Internet service provider which hosts your website. Publish a M ediabook by FTP from the Analyzer to create a fully functional multimedia webpage that can be viewed in any browser. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 106 6.2 Sharing video files Sharing video is a function of the Tray. All Dartfish features which create or import video clips add them to the Tray but video files can also be loaded by drag-and-drop from the Item s L is t to the Tray. Remember that multiple files can be selected for loading by holding down the [Ctrl] key while clicking on the files. Once video clips are loaded, click the Tray's Sh are button. Sharing Dartfish Assets with video Dartfish creates a small 'Dartclip' file for each video clip. This contains information about key positions, notes, cue in and out settings etc - all the value added features that Dartfish brings to the video clip. The Sharing process also ensures that the Dartclip file is shared with the video file. If the receiver of the video clip is a Dartfish user and chooses to retain the Dartclip file they will benefit from all the additional information added to the video clip. 6.2.1 Video sharing wizard The Vide o Sh arin g W izard The process of sharing is guided by the Video Sh arin g W izard. Three steps are common to all sharing destinations. 1. Selecting the sharing Des tin ation - Click on a destination then on the N ext> button (at the bottom of the window) to proceed. 2. Selecting which videos you wish to share. "Check" those to be shared as shown below or click the Select All button: 3. Choose the video settings (encoding profile) appropriate for the selected destination (see Video settings in the Gettin g fam iliar chapter). Specific additional information may be entered according to the selected destination. Read the information displayed in the wizard to complete this information. © Dartfish. All rights reserved. - Version 6 - Dartfish outputs - publishing & sharing 6.2.2 107 Sharing video by Dartfish TV Sharing video using Dartfish TV has some key differences from the other sharing media: 1. No Dartclip data shared: Only video and no Dartclip is passed to Dartfish TV. Category\Value is used to create searchable keywords on the platform. Key positions can only be shared by publishing a Mediabook. 2. Playable online AND offline? Video clips can be played online by anyone with access to the channel. Optionally video can be made available for offline viewing - this is defined at the creation of the channel. 3. Inclusion of attachments: Any file can be attached to video clips during the sharing process. 4. 2 Videos uploaded: An encoded version suitable for online viewing and a version for offline viewing which can be higher quality The video sharing wizard 1. Sharing Des tin ation - Click Dartfish TV then the N ext> button. 2. Login - after providing your login name and password select the channel and collection within that channel to which the video files will be added. 3. Selecting which videos you wish to share. "Check" those to be shared as shown below or click the Select All button: 4. Dartfish TV categorisation. Mandatory keywords and optional (uncategorised) key words can be added. These make it easier to find specific videos by filtering by keyword. It is also possible to add notes to describe the video content. If more than one file is uploaded this step is omitted and notes must be added at step 3. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 108 5. Select Publishing Options. For online viewing select whether the full video is shown or a shorter trailer that will assist viewers to decide whether to download the full video for off-line viewing. For offline viewing decide what quality of video to make available for download: the original quality, a high quality compressed version or re-use the same video that is displayed on Dartfish TV. File attachments can be added at this step (not available when doing bulk upload). 6. 6.3 The final step encodes the video and posts it online. Producing MediaBooks A M ediaBook allows you to share your analysis by packaging video, key positions, text and audio comments, and drawings together. Share M ediaBooks using the Internet, CD or sending them by email. A Mediabook offers an electronic output (as shown below) or a paper printout of key positions and keyposition annotations. © Dartfish. All rights reserved. - Version 6 - Dartfish outputs - publishing & sharing 109 The image above shows a M ediaBook displayed as a web page in an Internet browser. It contains the following features: An alys is Selection : More than one analysis can feature in a M ediaBook. Each item in the Storyboard is included (read the Analyze Performance chapter to learn more about the Storyboard). Video Player: Video clips are saved in Macromedia Flash format which can be viewed on most Windows computers. One video is generated for each Storyboard item. The player controls allow clips to be played frame by frame and to play in a loop. For a larger image, it is also possible to play the clip full-screen using your Windows default Media Player. Key Pos ition s Selection : Click on a Key positions thumbnail to display the corresponding key position. The key positions of all the clips in the An alyzer at publish time are included in the M ediaBook. Select "A", "B", "C" etc. to display the corresponding list for each clip. The "Analysis" key positions choice, as in the illustration above, varies according to the display mode selected at publish time: 1. Sin gle-s creen mode: image transformation (such as zoom or mirroring) and global drawings are reflected in the key positions. 2. Split-s creen (or Blen d) mode: key positions are split-screen pictures of every key position for which the labels match. Video clips are automatically re-synchronized at every key position. If no labels match, no An alys is key positions are created. - Version 6 - © Dartfish. All rights reserved. 110 Dartfish User Guide Com m en ts : The Analyzer allows you to type or record comments for each item in the Storyboard and to do the same for each key position. These are included in the M ediaBook. this Analyzer comment... ...becomes this MediaBook comment Slides h ow View : The Slides h ow View displays the key positions as larger images and includes printing options for them. Pers on alization : The M ediaBook can be personalized with your organization's logo or perhaps a photograph of yourself. This can also be a link to your website. 6.3.1 Step1 - Select destination Start the creation of a M ediaBook by clicking the button to the right of the An alyzer s toryboard. This displays the first step of the M ediaBook wizard where the choice of publishing destinations is made. The choice of destinations varies according the edition of software used but the full list of choices is shown below. © Dartfish. All rights reserved. - Version 6 - Dartfish outputs - publishing & sharing 111 After making your choice of destination, click the N ext button. 6.3.2 Step2 - Mediabook settings The M ediaBook settings step is used to: Assign a File n am e: This will be used to name the M ediaBook file(s). Personalize the M ediaBook: The M ediaBook can optionally be personalized with your logo and website address. You will also want to include a title that will appear at the top of the M ediaBook. Add h igh qu ality fu lls creen video: It is possible to include an external Windows Media video with the M ediaBook; these will be played using Windows Media Player and not the M ediaBook. This function may not be desirable if the size of the M ediaBook is important, for example if being sent by email. - Version 6 - © Dartfish. All rights reserved. 112 Dartfish User Guide Choose File Option s : These choice of file option is only available if the M ediaBook is being published to the "My Computer" option, otherwise the most appropriate option will be used according to the destination selected in the first step of the wizard. If the M ediaBook is saved for u s e w ith Dartview er, all files are packaged together into a single file which can be read and displayed by the Dartviewer freeware software. Dartviewer is automatically installed on all computers with Dartfish but for non-Dartfish users, Dartviewer can be included with the M ediaBook or downloaded from the Dartfish website. This option is automatically used for CD/DVD and emailed M ediaBooks. If the M ediaBook is saved for u s e w ith an In tern et brow s er, an HTML file is created with the additional files required to create the page also added into a separate folder. This option is automatically used with M ediaBooks for the internet. 6.3.3 Step3 - Video settings This step allows you to select a Flash encoding profile for the M ediaBook and, if the "include high-quality, fullscreen video option" was selected in the previous step, you can also select a Windows Media encoding profile for those videos. Encoding profiles compress the original video files substantially from the original AVI video that is captured from your video camera. The amount of compression depends on the profile chosen. Click the E dit th e profiles link to get information on the relative file sizes. © Dartfish. All rights reserved. - Version 6 - Dartfish outputs - publishing & sharing 6.3.4 113 Step3 - Preview Step 3 of the wizard also allows you to preview the choices you have made in the previous steps, including your personalization's and the quality of compressed video files. To see a preview, click the Preview button. The preview will be displayed in your Browser or in Dartviewer depending on the choices made. 6.3.5 Step4 - Publishing The publishing step will depend on the destination. My Computer Choose or browse for the file location where the M ediaBook will be saved. Email There are no further choices. The files will be processed and a message displayed when this has completed. You may choose to attach the Dartviewer freeware to the email if it is being sent to recipients who has not previously installed Dartviewer. They will receive instructions on how to install Dartviewer. CD/DVD Final information about the CD/DVD burner to be used and a disc label are provided. Clicking the N ext button will "burn" the CD or DVD. FTP An FTP profile is selected in this step and, if necessary, a password is entered.

Your network administrator or website host must provide you with this information. 6.3.6 Mediabooks on Dartfish TV Whereas other Mediabook formats almost have the same behaviours as the original Analyzer project on which they are based, Mediabooks published on Dartfish TV are very different: 1. Video assets can be downloaded. Key positions won't be included in the download though 2. Inclusion of attachments: Any file can be attached to video clips during the sharing process. 3. Different storyboard elements presented as segments on a single timeline. It is also possible to select and play individual segments. 4. Key positions from individual split-screen or blended video clips cannot be selected for individual clips. Instead only the Keypositions with matching labels are published as a single marker. When this marker is selected the videos are synchronised at this point. 6. 2 Videos uploaded: An encoded version suitable for online viewing and a version for offline viewing which can be higher quality The Mediabook above has the following features: m arkers and m arker com m en ts (written & audio), Keyw ords allow filtering for other video sharing the same keywords, print options for m arkers , download of video, audio comment and attachment. © Dartfish. All rights reserved. - Version 6 - Dartfish outputs - publishing & sharing 6.3.7 115 Publishing to Dartfish TV The video sharing wizard has the following steps 1. Sharing Des tin ation - Click Dartfish TV then the N ext> button. 2. Login - after providing your login name and password select the channel and collection within that channel to which the Mediabook will be added. 3. Selecting which Storyboard items to be included in the Mediabook. "Check" those to be shared as shown below or click the Select All button: 4. Dartfish TV categorisation. Mandatory keywords and optional (uncategorised) key words can be added. These make it easier to find specific videos by filtering by keyword. It is also possible to add notes to describe the Mediabook content. 5. Select Publishing Options. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 116 For offline viewing decide what quality of video to make available for download: a high quality compressed version or re-use the same video that is displayed on Dartfish TV. File attachments can be added at this step. 6. 6.4 The final step encodes the video and posts it online. Saving movies from the Analyzer New movies can be produced featuring all the contents of the Analyzer Storyboard. The movie saved will reflect the content of that analysis including: Drawings Split screen or blended comparisons Cue in/cue out positions Click the M ovie button to turn the storyboard into a movie. With this functionality, Dartfish is in effect video editing software in that it is being used to join separate clips together, however while it does not include transition effects or allow inclusion of still images, it is capable of creating movies with features that are not possible with other software such as: Split screen or blended comparisons © Dartfish. All rights reserved. - Version 6 - Dartfish outputs - publishing & sharing 117 Specialist text captions such as timers Specialised drawings such as angles and data display and also including drawing effects such as fade in/fade out and tracking 6.4.1 Step1 - Video settings The first step is to choose an encoding profile. If this is changed from DV, the resulting video will be compressed but will loose some image quality. Find out more about encoding profiles in the topic Converting video The encoding profiles include half and quarter speed profiles which allow you to produce video which will play back in slow motion. 6.4.2 Step2 - File information In this step, a File n am e and Des tin ation folder is assigned to the new video clip. The Con flictin g file option s choice defines whether existing files with the same name should be replaced or whether the new file will be renamed. If a file does get renamed it will be suffixed with a number. In the example above the new video clip would be called "Bobs drive hole 5(2)" Categorization of new video clips Users of the Category/keyword file management system will be please to see that video files can be categorized as they are saved. The method of building and using a form is identical to that used for capturing video files with the Video recorder or InTheAction modules. Refer to those chapters for further information. - Version 6 - © Dartfish. All rights reserved. 118 6.5 Dartfish User Guide Creating still images Key positions can be printed or saved as still images. Click the Pictu res button to the right hand side of the Analyzer Storyboard to publish Key Pos ition s as still images. You can publish pictures to the following destinations: Printer. Dartfish offers a choice of layout templates to print images. Some include the notes and title information. My Computer. Save images as image files to a location on your computer. Email. Images will be attached to a new email using your default email program. Select a destination and click the N ext button. 6.5.1 Saving pictures to 'My Computer' Similar to other Dartfish processes where files are saved, you will assign a File n am e and Des tin ation folder to the images and optionally the images can be categorized (see below). Click the net button to save the image files. By default they will be 720x576 pixel JPEG images (or 720x480 for NTSC video). Categorization of images Your pictures can be categorized as they are saved. In the example below the file is named but can also be filed under values in the categories of Sport, Player and Club. The method of building and using a form is identical to that used for capturing video files with the DV Import or InTheAction modules. Refer to those chapters for further information. © Dartfish. All rights reserved. - Version 6 - Dartfish outputs - publishing & sharing 6.5.2 119 Attaching pictures to email There are no further steps to attaching pictures to email Only email software like Outlook and Outlook Express can be used. If you use another type of email such as AOL or web based email like Hotmail, YahooMail etc then you should save the pictures using the 'My Computer' option and attach them through the software or website itself. 6.5.3 Printing Pictures Two steps are required to print your pictures. In the first, the printer you wish to use will be selected. select The printing preferences button opens the print settings button for the type of printer you use. The choices available depend on your printer and you should refer to your printer's documentation if further explanation is required. You will be able to use these preferences to choose a print quality and a paper type; these are especially important choices if photoquality paper is being used. - Version 6 - © Dartfish. All rights reserved. 120 Dartfish User Guide Click the N ext button to continue... Before printing, choose from one of a number of layouts. The preview gives an indication of the layout but not the quality of the printed page. Note that both the label and notes information for each picture can be included on the page. Clicking the Prin t button will print the images according to the chosen layout. 6.5.4 Snapshot images All Dartfish modules with video playing capability offer a Sn aps h ot tool which can be found below the video display. The Snapshot tool is used to create a still image from the current video display. Use it in the following ways: Click the button to save the current image as a BMP (or JPEG) file to your computer. Click while holding the control key (ctrl) on the keyboard to copy the image to the MS Windows clipboard. Now it can be pasted into any other application supporting copy/ paste of images. For example, you could use this to insert an image onto a MS PowerPoint slide. © Dartfish. All rights reserved. - Version 6 - Dartfish outputs - publishing & sharing 6.6 121 Recording analysis The other publish tools covered in this chapter provide various methods of sharing analysis with others. Of course, the actual process of using the Analyzer can itself be an invaluable feedback tool when its tools are used to illustrate and compare performance. This is the reason behind the An alys is Recorder; it is a method of making a real time recording of your use of the Analyzer and including your voice as a sound track to the resulting WMV video. To appreciate the value of analysis recording, imagine sitting with an athlete and using the Analyzer's features to explain the latest skill he/she is attempting to master. If you imagine that you could film your use of the Analyzer and include a commentary of your coaching then you would be very close to the functionality of the An alys is Recorder. The analysis recorder is only available in the Prosuite and Team Pro editions of Dartfish 6.6.1 Enabling the Analysis Recorder Start by selecting the An alys is Recorder tab and selecting the E n able Recorder option. This results in new controls, Record and Pau s e Recordin g appearing in the Analyzer's video playback controls. 6.6.2 Setting clip properties Because, the Analysis Recorder creates a new video clip, a file name should be provided for it. If left blank, the file will be given the name "Untitled(x)". Setting clip properties also allows you to create a form that will let you categorize the new video using Dartfish's Keyword video management system. The use and creation of the Analysis Recorder's Clip Properties form is identical to that used for all Dartfish's Capture tools (see Video recorder in the Video L ibrary chapter). A form such as that shown below is used to "label" the clip appropriately making it easy to find in the Item s L is t by selecting any combination of the values entered. - Version 6 - © Dartfish. All rights reserved. 122 6.6.3 Dartfish User Guide Other clip properties In addition to file name and category/keyword for each clip you will also want to define the quality of the final video by choosing an appropriate encoding profile and the file location for the end result. Encoding profile The encoding profile selected defines how much the video will be compressed. Selecting an appropriate encoding profile is a trade off between the size of the resulting file and its image quality, for example, you are unlikely to want to send extremely large files by email. There are three profiles, high, medium and low quality, specifically created for the Analysis Recorder. The principal difference between these is in the number of frames per second. Capture Location The capture location defines where the Analysis recorder video will be saved in the Windows folder system. Remember that this should be included Library if this file is to be visible when using the Category/Value video management system. The links provided allow you to select a new capture location and to open that location. 6.6.4 Setting recording device In this case, the recording device is being used to record an audio commentary and NOT to capture new video from a camera. Select a sound recording device from the list. It may be possible to choose between more than one device, for example a built-in or external microphone on your computer or, if it is connected and switched on, your video camera. © Dartfish. All rights reserved. - Version 6 - Dartfish outputs - publishing & sharing 123 If you select your computer's sound card from the list you will be offered a further choice of audio inputs that connect to the sound card. The link to "Configure the device" allows you to set recording levels for that device. 6.6.5 Using the Analysis Recorder Start recording using the Record button. Then, imagining that the athlete(s) you are analyzing are sitting next to you (perhaps they are), use the Analyzer's comparison and drawing tools to explain and illustrate your analysis while recording your comments and advice. Everything you do on the video screen and everything you say will be recorded as a new video clip. If you need to pause recording to exclude anything that you don't want to include on the final recording, click the Pau s e button. When your analysis is complete, remember to stop recording by clicking the Stop Recordin g button. The resulting video clip be saved on your computer and will appear in the Tray ready to be played or shared. You should remember that lengthy analyses will create large video files. Here are some preparation ideas to help you make your presentation efficient and succinct: Open the video clips to be used in the analysis into the Story Board or the Tray. Trim video clips to show the relevant part. You could also zoom and flip and synchronize them in advance as appropriate. Create key positions complete with drawings. - Version 6 - © Dartfish. All rights reserved. Chapter VII Unique ways to view sport - SimulCam & StroMotion 126 7 Dartfish User Guide Unique ways to view sport - SimulCam & StroMotion With SimulCam and StroMotion, Dartfish offers uniquely creative ways of observing, analyzing and understanding sport. Each creates images that can never be seen in real life; StroMotion allowing the athlete to leave a clone of him/herself behind as he moves; SimulCam allowing two athletes to virtually "compete" against each other when in reality their performances took place at different times. You may have already seen these techniques in use because Dartfish provides this technology to television broadcast companies around the world. They use it to illustrate and give their audiences a better understanding of sport and now you can benefit in the same way: Perhaps SimulCam or StroMotion will be the only way that you can compare the tiny differences between competitors; the tenths of seconds separating competitive skiers for example, or subtle differences in a tennis serve. Perhaps the images will help teach technique to your development squad in a way that they will have never seen before. Or perhaps you will use the technology to inspire athletes by having them compete alongside the great names of your sport! 7.1 Compare with SimulCam The SimulCam technology provides you with a unique analysis capability for comparing two athletes' performances blended onto a single background. This enables you to view and analyze often imperceptible differences between these performances, and discover precisely what made one performance stronger than the other. To compare performances, SimulCam matches the backgrounds of 2 video images so that even if the camcorder pans, zooms or tilts it continues to track the background features. Using this information, the two backgrounds can be blended into a single one. In essence, SimulCam has a similar purpose to using the Analyzer module's Bas ic blen d view, however the end result is vastly superior: Basic blend is unable to track the relative movements of the background features, making comparison near impossible if the camera zooms or pans during filming. Basic blend results in ghostly, semi-transparent figures whereas SimulCam creates a more realistic picture. Required to use SimulCam: © Dartfish. All rights reserved. - Version 6 - Unique ways to view sport - SimulCam & StroMotion 127 Camera on tripod Pan, tilt and zoom allowed during filming. Video clips can be recorded at different times but must be taken by a camera in exactly the same position. The steps in using it are to: 7.1.1 1. Step 1 - clip selection and synchronization. Two video clips are loaded. To be comparable the two clips should then be synchronized. 2. Step 2 - camera movement calculation. Background features are matched and the amount of camera pan and zoom is calculated. 3. Step 3 - blending, preview and saving the clips. You can also save the SimulCam project if you wish to make changes to any of these steps later. Getting good SimulCam results Remember, the SimulCam technology matches backgrounds of two video clips; it will have difficulty doing this under the following conditions: Insufficient number of background objects For example; snow. Imagine trying to identify the same point on a white background from frame to frame. Your brain is still better than a computer's so "what the eyes cannot see, the computer cannot!". Avoid this by not zooming too closely on the subject. Even on snow, shadows, rocks, slalom gates etc can still be used but only if enough of these distinguishable objects appear in each frame of video. Background is blurred Its the same problem, if background objects become blurred or out of focus, SimulCam is unable to calculate where they have moved to. Use a tripod or another solid object to mount the camera. Zoom and pan smoothly and slowly. Backgrounds are different SimulCam can only compare if the content of the background is similar in each video clip. Always film from the same position. If it helps you remember, mark the spot! It does not matter if a different zoom has been used for each clip - the backgrounds only have to contain similar objects filmed from the same direction. SimulCam will calculate the difference in zoom. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 128 7.1.2 Step 1 - clip selection and synchronization Step 1 of the SimulCam clip creation process consists of: Loading two video clips containing the performances to analyze. Synchronizing the clips for optimum comparison. Trimming the video by selecting appropriate cue in & out points. 7.1.2.1 Loading video clips SimulCam compares two clips. Drag & drop each clip you wish to compare from the items list on to SimulCam's left and right video display windows. At this point, you can exchange either clip for another clip by simply dragging and dropping a different clip from the Item s lis t or Tray. The video format must be DV (.avi), for example it is not possible to create SimulCam images from Windows media (.wmv) video or MPEG (.mpg). Also, the two clips cannot be of different formats (for example, NTSC and PAL). 7.1.2.2 Synchronizing video clips SimulCam has a set of easy-to-use tools to help you synchronize the two video clips. These tools are located at the bottom of the SimulCam window. To synchronize the video clips: 1. Click and drag the timeline cursor until you see an easily identifiable moment in the first video clip. For example, find the instant where a long jumper's foot hits the board, when a skier passes a gate, when a golfer hits the ball etc. 2. Click and drag the yellow timeline (this represents the second clip) left or right until you see the same image in the second video clip. Fine-tune the video frame selected using the left and right cursor movement keys of your keyboard © Dartfish. All rights reserved. - Version 6 - Unique ways to view sport - SimulCam & StroMotion 129 It is important that you choose a starting frame with clear static elements that appear in both backgrounds. This will help you align the backgrounds in the next step. A "perfect" synchronization does not always yield a perfect analysis. The overlap between both performers may be too high, hiding important details. In this case, try to add one or two frame shift between both video clips. If the video clips contain synchronization points, they are automatically synchronized when loaded. 7.1.2.3 Trimming the clips This means selecting the portion of the video clips you want to analyze. This is done by setting cue in and cue out points. To set cue in & out points 1. Position the red cursor at the beginning of the portion and click on the Set In button ( 2. ). Position the cursor at the end of the portion and click on the Set Ou t button ( ). It is worth taking time to trim the clip to the section of the video you wish to compare as this considerably reduces the time taken to produce the final result clip. Also, experienced SimulCam users will be able to avoid sections of video where SimulCam is not able to make comparisons. 7.1.3 Step 2 - camera movement calculation In this step, calculation of the camera movements is initiated. This is required by SimulCam to blend the two performances onto a single background. In this process, similar features in the backgrounds of the two video clips are manually aligned by one of two methods: 1. Drag & zoom align m en t - Backgrounds are aligned by blending the first frame of each clip then zooming and dragging one frame above the other until backgrounds match. 2. M atch ed align m en t poin ts - Several matching static background features are marked with alignment points on the first frame of each clip. Which method is best? We recommend that you try both methods to decide which one is most comfortable for you. By default, your software uses the Drag & zoom align m en t method. Use the following notes as a guide. In general, manual alignment by the Drag & zoom align m en t method is quicker. Drag & zoom align m en t requires you to zoom using scroll function of your mouse or the [+] and [-] keys of your numeric keypad (refer to your laptop documentation). If neither of these are convenient for you then M atch ed align m en t poin ts might be a better choice. The M atch ed align m en t poin ts method is sometimes a better choice when the video - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 130 images do not match well. To select the calculation method The calculation method can be changed at any time before or during SimulCam. 7.1.3.1 1. Select Tools >Option s from the menu bar (or press F3). 2. Select the Sim u lCam topic from the list on the left. 3. Select the mode. Note that you can Set as defau lt your choice of calculation method. Drag & zoom alignment method The Drag & zoom align m en t method consists of dragging and resizing the image of the first video clip on top of the other clip until the two backgrounds match perfectly. Step 2 using Drag & zoom alignment looks like this: Images from both videos are blended but the backgrounds still have to be aligned for each of the 3 pairs of images displayed on the left hand side of the module. Adjusting Zoom © Dartfish. All rights reserved. - Version 6 - Unique ways to view sport - SimulCam & StroMotion 131 If the camera used different zoom while filming the two video images this can be compensated for by resizing the top video image. 1. Click the blended video images. 2. Adjust the size by using the mouse scroll function. If your mouse has no scroll function or it does not operate zoom then use the [+] and [-] keys on the numeric key pad of your keyboard. Different laptops use different methods of activating and operating the numeric keypad; refer to your laptop's manual to find out. Aligning backgrounds When images are a similar size, they can be aligned - although you may have to align then zoom again to get a perfect match. 1. Click & drag anywhere on the blended video images, the top image will move over the image below it. 2. Focus on one or more objects in the background; the stands, objects on the field, posts, equipment, etc. and align those objects. Repeat Alignment for the other pairs of images The first pair of images show the background of the two different video clips. The alignment process needs to be repeated for the two remaining pairs of images. These pairs are used to calculate movement from one frame to the next in each clip so if movement is slight this will be much quicker than aligning the different video clips. 1. Click the second pair of images listed on the left hand side of the SimulCam module. 2. Align them. 3. Click the second pair of images listed on the left hand side of the SimulCam module. 4. Align them. The end result of step two is illustrated below. Click the N ext button to proceed. - Version 6 - © Dartfish. All rights reserved. 132 7.1.3.2 Dartfish User Guide Checking alignment Check the alignment quality using the transparency cursor. Drag the cursor to the left and to the right. If you feel that the background is moving, it means you need to keep aligning the two backgrounds. If you still cannot align the background, after repeated zooming and alignment, this could mean that the camcorder tripod moved during your recording session. In this case, it is not possible to create SimulCam video clips. You still can compare performances but you will need to use the split screen functionality of the An alyzer module. © Dartfish. All rights reserved. - Version 6 - Unique ways to view sport - SimulCam & StroMotion 7.1.3.3 133 Matched alignment points method The M atch ed align m en t poin t method is a process of placing markers on similar features in the background of both video clips. The alignment point window is illustrated below: Selecting background alignment points. In this method, at least two points are set on objects in the background of the first image and then set on the same objects on the second background. This is repeated for all three pairs of images listed on the left hand side of the SimulCam module. It is best to use obvious points of high contrast as illustrated in the following pictures: Also it is essential that these background points are fixed objects: People or the top of the slalom gate in the above clip would not be good choices because they move! To define alignment points. 1. Click on the first clip's title above the video display. A frame of the first clip is displayed in the main screen. (Ski 1 in the illustration below) 2. Click the left mouse button on a static background feature. The feature is marked as shown below. 3. Now click a second and perhaps a third object. They will be labeled similarly; you must set a minimum of two alignment points but defining more may improve the background - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 134 alignment. 4. Click on the second clip's title above the video display. A frame of the second clip is displayed. 5. On the second clip, click the same background objects that you selected on the first clip in th e s am e order s o th at th e n u m bers m atch ; the thumbnail on the left displays the previous selections and can act as a guide. 6. Click on Vis u al Ch eck on the process bar. A combined image of both frames is displayed. The backgrounds should appear aligned. If you need to delete a numbered mark because the elements are not in the second image or are not positioned correctly, right-click on the mark you wish to delete. Then left-click in the correct position and a marker with the same number appears again. If the backgrounds do not match in the Vis u al Ch eck, make sure that the alignment points are placed correctly and that point 1 matches point 1 in each image etc. If backgrounds still do not match then adding further points will improve accuracy. 7. Select the second pair of images from the thumbnails on the left of the SimulCam module. These images compare camera movement form one frame to the next in the same video clip. 8. This time feature points are already set but you need to check they are positioned correctly. Use the techniques described in step 6 to remove and reposition feature points as required. 9. Repeat for the third pair of images. 10. When complete proceed to the next step by clicking on the N ext button. 7.1.3.4 Adding new alignment frames Both methods to complete step 2 require that you match the backgrounds in the starting frame of your clips. However, if the backgrounds in this frame are too different, they do not include clear common background elements or the objects are blurred you will need to set a different start frame. To set a new start frame. 1. Go back to step 1 by clicking the back button. 2. Set a new cue in at a start frame that is more appropriate. 3. Repeat step 2. Setting new alignment frames. It is essential that the start frames match but additional frames can be set where backgrounds can be realigned. This might be necessary for clips that "jump" because of a change of camera angle, or because the images have become blurred during panning or the clip does not include part of the action in a particular frame. New alignment frames are represented by flags in the timeline. Once you add a flag, you will be able to realign the backgrounds in that particular frame as described previously. © Dartfish. All rights reserved. - Version 6 - Unique ways to view sport - SimulCam & StroMotion 135 To add a flag. 1. 2. Go back to step 1 by clicking the back bu tton . Drag the current position indicator along the timeline to the new alignment frame. 3. Click on the Add flag bu tton . A new flag is added to the timeline. A red flag indicates that the background alignment still needs to be performed for this particular moment 4. Other icons allow you to jump to the next or previous flag and to delete a flag. 5. Repeat step 2 for each flag added. 7.1.4 Step 3 - blending, preview and saving Step 3 enables you to: Select the blending mode Start the calculation of the SimulCam clip and watch a preview Save the SimulCam video clip 7.1.4.1 Blending mode The SimulCam image quality may vary depending on the blending mode. You can choose from three modes and use the preview to experiment with what works best for your sport. 1. M otion -bas ed: In most cases, this is the best mode to use for generating a blend. It is based on the camera movement. 2. Color-bas ed: Use this mode when your clip features a lighter colored background than the performer. For example, snow, sand, concrete. Light colors are "pushed" into the background. 3. Con s tan t: This is the fastest blend calculation mode, however, the resulting quality is poorer than the other modes. Use this mode when you want to get a rapid result. Use the drop-down list to select the blending mode 7.1.4.2 Previewing your clip It is not necessary to use the preview function but it will help you decide the best blending mode and whether additional alignment is needed. To preview, click on the Start preview button. The SimulCam clip will be displayed in the main screen as the calculation progresses. At any moment, you can decide to stop the calculation by pressing the Stop preview button. You can now experiment with different blend modes to compare which gives the best result. If the SimulCam can be improved, go Back to the previous steps and redo cue in, alignment, - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 136 blend mode etc. This done, it may be that there is still a progressive misalignment of the backgrounds. If this happens, stop the preview and try one of the following. 1. Add an alignment flag to the frame where the background misalignment begins (see Addin g n ew align m en t fram es ). 2. Select a different first frame - as described in Step 1. It is much quicker to preview using Con s tan t Blen din g m ode. When satisfied that alignment is correct switch blending mode to M otion -bas ed or color-bas ed for a better quality result. 7.1.4.3 Saving SimulCam results There are two potential end results of a SimulCam project: the creation of a new video clip using the Pu blis h process the SimulCam project itself. Saving the SimulCam project To do this select the Save... option from the File menu. Saving the project is not always necessary but may be useful if you wish to return to the project to make changes in the future. SimulCam projects appear in the Item s L is t represented by the following icon: Starting a new SimulCam project To initiate a new project select the N ew option from the File menu. 7.1.5 Publishing new video clips The publish process uses a wizard to guide you through creating new video clips resulting from SimulCam, SimulCam Fixed, Stromotion and Stromotion fixed. It is used to: Save and name the video clip. Categorize the new clip using categories. Initiate the Pu blis h process by clicking the Publish button at the bottom right of each module. 7.1.5.1 Choosing video settings The first step is to select which encoding profile you wish to use for the clip. A range of encoding profiles exist to allow you to select an appropriate format for the eventual use and location for the video. For example, if the video clip is lengthy or needs to be sent by email, you may decide to use an encoding profile which compresses the result into a file of smaller size (see Converting video in the Getting Familiar chapter to learn more about video settings). © Dartfish. All rights reserved. - Version 6 - Unique ways to view sport - SimulCam & StroMotion 137 After selecting a profile, click the N ext button to continue. 7.1.5.2 Assigning file name, destination and categories File name Type a name for the video clip in the File N am e text box. If this box is left blank the generic filename of "Untitled" will be applied. Categorize clips while saving If you use Dartfish's Keyword video management system (see Organizing your library in the Video Library chapter) then you can benefit from categorizing new video clips as they are saved. The method for doing this is to create a form listing a box each category that you wish to use then selecting existing keywords from these categories or entering new ones. An example is shown below. The same method is used for categorizing captured video. Destination folder This is the physical location on the computer (drive and folder) where the new clip will be stored. Type the location or click the Brow s e button to search and select a folder. Conflicting file options If the file name matches that of another file in the destination folder the con flictin g file option s setting allows a choice of overwriting the original file or renaming the saved file. If the latter option is chosen, the new video file will be suffixed with a number. For example, if "World cup" already exists a new file would be called "World cup(1)". 7.1.5.3 Video creation The final step automatically initiates the creation of the new video file according to the settings chosen in the wizard's previous steps. The time taken to render the new video will depend on the power of the computer and the size of the new file; progress of creation is indicated. You will be notified when the publishing process is complete and, by default, the new video clip will be added to the Tray, allowing convenient access to replaying it in the Player or An alyzer modules. 7.1.6 Next steps SimulCam & SimulCam Fixed are unique analysis capabilities for comparing two athletes' performances blended onto a single background.

All rights reserved. 138 Dartfish User Guide motion of a performer in a panoramic still image or a video clip. The Analyzer module offers another way of highlighting key frames and uses them to bookmark these moments and turn them into still images (read the chapter about the Analyzer to learn more). Having created these unique images, you may want to share them by CD, email or internet (see Sharing video files in the Video Library chapter). 7.2 Dissect motion with StroMotion Images produced by StroMotion give an athlete and coach unique insights to how an action develops. It produces a panoramic still image or a video clip that contains collections of frozen images, revealing how rapid technical changes are made. To imagine how this might help you, think of times when it might be useful to show your athlete their position on one frame of video then show it's consequences in another frame. How about educating your junior team about the correct sequence of actions to use? Sure you could print out some still pictures but StroMotion offers a juxtaposition of images which truly reveals how one action leads to the next. © Dartfish. All rights reserved. - Version 6 - Unique ways to view sport - SimulCam & StroMotion 139 The process of creating a StroMotion clip involves 4 steps: Step 1 - Load & trim the video clip Step 2 - Camera movement computation Step 3 - Panorama reconstruction Step 4 - Draw clones & save results 7.2.1 Step 1 - Load & trim the video clip Loading the video clip Open the clip of your choice from the items list or tray. The chosen clip may be changed by simply loading a different clip. Trimming the clip (set cue in & out points) The clip should be trimmed at the beginning and end of the movement that is to be turned into a StroMotion image. Choose a start position with clear background features. This will help you match background features in step 2. Click the N ext button at the bottom right of the StroM otion module to proceed to the next step. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 140 7.2.2 Step 2 - Camera movement computation In step 2 camera movement is calculated. This is initiated by matching at least two background features in successive frames of the video clip by setting alignment points. StroMotion then computes the movement of the camera throughout the clip. The points set as alignment points should be static, people are not a good choice of alignment point! They should also be obvious points in the background as StroMotion can't track the objects if they are blurred or similar in colour to the surrounding background. To set alignment points Click the left mouse button while pointing at an object (a flag, center line, pole, goal, etc.) that is present on both frames The red alignment point which appears is labelled with a number. The same marker will appear on both images. To exactly position alignment points on features, zoom in on that feature. To do this click the mouse on the feature while holding down the [ctrl] key on the keyboard (Left-click to zoom in and right-click to zoom out) To adjust alignment points In the image above the feature point labelled "2" is not marking the same place in both images. To correct this: 1. Right click on the incorrectly positioned alignment point to delete it. 2. Then left click the position where the alignment point should be. © Dartfish. All rights reserved. - Version 6 - Unique ways to view sport - SimulCam & StroMotion 141 Repeat this setting and adjusting operation until you have selected at least two alignment points You can check how well the alignment points match by clicking the Vis u al Ch eck button. A window opens showing the athlete moving against a static background. If the background appears to move or shift, you should check your alignment points or add further points until the background is relatively stationary. Calculate camera movement Click the Start button. Shading inside the timeline shows how much of the process is complete. When the calculation is complete, you are ready to click the N ext button to go to the next step. The Sh ow w arpin g button allows you to check the result while the clip is being processed. If the background appears discontinuous as it is constructed , stop the computation and make further adjustments to the alignment points. This may also be caused by the tripod moving during filming. 7.2.3 Step 3 - Panorama reconstruction Usually no action is required in step 3 as the panorama reconstruction begins immediately. 7.2.4 1. If it doesn't start then click the Start button. As before, timeline shading will show progress. 2. Click the N ext button to proceed to the next step. Step 4 - Draw clones & save results This step is where you select the parts of the image which will stay fixed on the subsequent frames of video and will appear as "clones" on the panorama image. To do this you will: 7.2.4.1 1. Identify key frames in the video clip where the performer or object is in a position of interest. 2. Draw around the "clone" object using a range of clone drawing tools. 3. Repeat the above for all key frames. 4. Save the project, result clip or panorama image Identifying key frames Your task here is to find frames of video showing the athlete (or another object) in a key position of interest. This is the moment of action that you wish to freeze. You should already be familiar with how to use the timeline to move through a video clip. It is worth remembering to use keyboard shortcuts [ctrl] + [left/right] cursor keys that will play one frame at a time and fine-tune your selection (read the Gettin g Fam iliar chapter to learn more). - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 142 to insert clones at a fixed interval use the Ju m ps ize control illustrated below to define the size of the "jump" and move backward and forward through the clip by this interval. 7.2.4.2 Drawing clone objects Having found a key frame of video - one in which an athlete or object is in a position of interest, that athlete or object now must be cloned. You are not restricted to cloning a single object, so select all objects of interest in each key frame. The objects or athletes that you want to clone are drawn, selected and manipulated using the tools on the right of the StroMotion module. Select tool - select clones or move selection. Rectan gu lar clon e tool - clone creation tool. Freeh an d clon e tool - freehand clone creation. Delete s election - deletes the performer/object selected by the select tool. Delete all - deletes all performers/objects on this frame. Zoom in /ou t - zooms in on the point on the image that is clicked (right click to zoom out). To create clones Use the Rectan gu lar clon e tool or the Freeh an d clon e tool tools to "draw" around the performer/object to be cloned. To use the Rectan gu lar clon e tool 1. Click the Rectan gu lar clon e tool button. 2. Then point the mouse above and to the left of the object to be cloned. 3. Click & drag downwards and to the right until the selection box encompass the object while including as little background as possible. To use the Freeh an d clon e tool 1. Click the Freeh an d clon e tool button 2. Click & drag around the object staying as close to the edge as possible. © Dartfish. All rights reserved. - Version 6 - Unique ways to view sport - SimulCam & StroMotion 143 If you miss part of an object during selection, don't delete the clone and start again, simply include the missed part as a new selection. More than one tool can be used and more than one selection can be made to create a clone as shown in the image below. Which selection tool is best? To answer that, remember that whichever tool you use, the selected area will stay fixed on the video image. If there is overlap between clones, the later clones will obscure the earlier ones. Use the freehand tool when there will be a lot of overlap between the clones. For example in a gymnastic rings routine or high jump. Use the rectangle tool when the clones will be spread out - the performer moves some distance between the key frames. For example in long jump. To edit clones 1. Select the clone to edit by using the Select tool of the cloned area. 2. Selected clones can be deleted , moved by click & drag, or reshaped by dragging the "handles" at each edge or corner, see these illustrated below. All clones in a frame can be deleted using the . Click the tool then click the outline tool, it is not necessary to select clones first to use this. By zooming in on the image more careful selection is possible. Click the left mouse button to zoom in and the right mouse button to zoom out. 7.2.4.3 Publishing StroMotion Creating StroMotion results is done using a Publishing wizard almost identical to that used by SimulCam. It is initiated by clicking the Pu blis h button in the final step of StroMotion and StroMotion Fixed projects. Publishing can produce a choice of two results described below. After selecting an output type and clicking the N ext button, the remaining steps are described fully in the SimulCam chapter (see Publishing new video clips in the Simulcam chapter). - Version 6 - © Dartfish.

Chapter VIII Tagging Video 148 8 Dartfish User Guide Tagging Video Traditionally, reviewing sporting performance on video is a linear process – you rewind the tape, press play and observe the action as it takes place. Of course your camcorder's fast forward button saves time but finding and replaying important moments in the game or competition essentially remains linear – and slow. Imagine how useful it would be to be able to mark and label these events on the tape as you are filming because you could later jump between these marks in any order you choose. You could review only the events of interest and choose to see related events: "Let me look at all the times our opposition scored" ceases to be a lengthy process of fast forward and play. Dartfish's Tagging module doesn't physically mark a tape but instead brings digital video onto the computer and allows you to create a searchable index of the video content. Each event is tagged with not just one label but a set of keywords that really identify what is happening. This process not only lets you search and review these events but compiles match statistics: "Which shot does my opponent most often score with?" is not only a question that can be easily answered, but the relevant shots can be replayed and analyzed. A short history of tagging If all this sounds familiar, that is because Dartfish Tagging is a combination of long-used tactical analysis methods: Notational analysis - the coach or analyst sits on the sideline with pen & paper ticking off or coding events as they take place in a game. Tagging does this using buttons which are clicked to code events. Video indexing - even before digital video, coaches attempted to make it easier to find useful moments in the video of the game by noting the time that they took place. This made it easier to fast forward to that point on the tape but it's easier still with Tagging; the events you code are listed in an index which can be searched and displayed nonsequentially. Is Tagging just for Team sports? No. While other Dartfish modules are used for technical analysis of isolated events. Tagging is more about a tactical analysis of the game as a whole while being able to focus on © Dartfish. All rights reserved. - Version 6 - Tagging Video 149 specific moments of choice. It is therefore useful for any sport where these qualities are of interest: Team sports, racket sports, combat sports, skating/gymnastic routines etc. 8.1 What is Tagging? Taggin g is the action of creating a video index, a list of E ven ts that occur in the video. Consider for example a video that contains a soccer game; the video index could look like this: Index Position Duration Event Type Player Team Event #1 23 s 7s Pass Defender Team A Event #2 1 min 13s 7s Free kick Striker Team B ... ... ... ... ... The Pos ition corresponds to the time in the video when the event occurred. The Du ration is a portion of the video when the events take place. Event type, Pass and Team are Categories . Pass, Defender and Team A are the keyw ords in each category. An event is fully defined by the Pos ition , Du ration and the categories' Keyw ords . It can be illustrated as follows: Once you have created your index, you will be able to retrieve particular events. For example, you may want to retrieve events that match the following criteria: Team = Team A, i.e. all events of Team A E ven t Type = Pas s and Team = Team A, i.e. all the passes of Team A It is important to be aware that the Tagging module doesn't just tag instantaneous events such as these examples, lengthy sections of video such as a team's ball possession can be tagged at the same time as the passes and free-kicks taking place during that possession. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 150 8.2 The Tagging Workspace To launch the Taggin g module, click on the Taggin g icon in the icon bar, or select Tools > Taggin g from the menu bar. The module workspace is illustrated below: It is composed of four different elements (clockwise from top left): 1. The L ibrary (more precisely the Tray of the library), which opens a collection of video clips to be tagged or reviewed. 2. The Video Pan el, which contains the video display and the different video controls which let you capture and replay video. This also has controls to display and hide the other panels and select the video source. 3. The Taggin g Pan el, which contains a set of buttons and other tools; some of which create a timestamp for each event and others which describe the event with values. 4. The E ven ts L is t, which contains the list of events, i.e. your video index. It also has features related to the management of events; editing, searching and import/export functions. These elements are described in more detail in the remainder of this section. When you launch the Taggin g module for the first time, the workspace may not look like the one illustrated above. If any of the four elements are not visible they may be displayed by using the View s Bar buttons at the top right corner of the video panel (see The Video Panel). 8.2.1 The Library It is likely that your tagging analysis will based on more than one file. Perhaps different periods of the game were recorded as separate video files or perhaps you are reviewing the video of an entire season. Dartfish offers you a simple way of working with as many video clips as you require. © Dartfish. All rights reserved. - Version 6 - Tagging Video 151 Loading all the clips you wish to analyze into the Tray section of the library allows you to: See events from of all clips contained in the Tray; allowing the events of many videos to be analyzed together. Search for events from all video clips within the Tray. View or tag multiple video files as if they were a single clip. When working with multiple clips, it is useful to know that the video clip highlighted with a green triangle is the one currently being played or tagged and that the Player's repeat options can be used to play each clip continuously as a single movie (See Video playback in the Gettin g Fam iliar w ith Dartfis h chapter) 8.2.2 The Video Panel The Video pan el is illustrated below. Mode bar - Version 6 - © Dartfish.

Select also gives access to the built-in panels and to create new panels to meet your specific needs (see Creating Tagging Panels). Tagging panels are saved as files just like Word documents or Excel spreadsheets. In other words, they exist independently of Dartfish software, they can be saved and organized using Windows file management, and can be attached to emails to be shared with others. The Edit button Opens the tagging panel editor. A tagging panel must already be open before the edit button can be used. The tagging panel - Version 6 - © Dartfish. All rights reserved. 154 Dartfish User Guide Although Dartfish tagging panels allow great flexibility and creativity in how they can be used, the tools on them principally have one of three functions: 1. Event tools - used to create events by time stamping the event and assigning it a descriptive value 2. Keyword tools - used to add additional keywords to events 3. Grouping tools - used to organize other tools into groups; either to improve the layout visually or ergonomically or to confer shared features on the group Tagging panels can consist of one or more pages, accessed by tabs. Buttons and tools for use at different times in the tagging process are placed on different pages to improve the ergonomics of the panel. 8.2.4 The Events List The E ven ts L is t contains the list of all events for all video clips in the current Tray: Events are selected by clicking on the row containing them. The video playh ead moves to the start of the event. Double-clicking an event both plays it and places Dartfish tagging in its Play E ven ts mode. Selected events may also be: Deleted using the Delete button Analyzed in Dartfish's An alyzer module ( Storyboard button) Exported as . cs v files using the Im port/E xport button Published as new video clips that can be stored on your hard drive (e.g. to make a highlights movie using video editing software) or directly burned onto a CD or data DVD (e.g. to give to team players or coaches), or uploaded to your dartfish.tv channel using the Pu blis h E ven ts button.

Click on the Select button and choose N ew from the context menu. 2. Click on the N ew Pan el icon 3. Select from the list of new project types. Create a new Blan k Pan el if you wish to start with an empty panel OR base a new panel on one of the built-in tagging panels. This displays the Taggin g E ditor window as shown below We recommend starting by using one of the Dartfish built-in tagging panels. Change labels and add/delete buttons as necessary for your sport. The Tagging Panel Editor The tagging panel editor has 3 sections, (left to right as displayed above): 1. The ToolBox contains buttons and other tools used to create and describe events. They are added to your tagging panel by drag and drop. - Version 6 - © Dartfish. All rights reserved. 156 Dartfish User Guide 2. The Taggin g pan el editor. This is where the content and layout of a tagging panel is defined. A new blank tagging panel already contains a tab group box allowing you to create a multi-page panel if required. 3. The Properties pan e. Properties are used to define the appearance and actions of tagging panel tools 8.3.1 Adding/deleting/moving/copying tools To add a tool to a tagging panel Items are placed onto the tagging panel editor by dragging and dropping them from from the Toolbox. New panels always have a tabbed grou p box with a single page, as show below. In order to place the tool on that page, it should be placed in the area denoted by the red line shown here: Adding subsequent items also requires care, in the image below, new tools should be placed on the gray shaded area if they are to appear on the same page as the other buttons. If placed below the page then that tool will be visible from all pages. © Dartfish. All rights reserved. - Version 6 - Tagging Video 157 To move an item Drag and drop the item you want to move to the new position. To move a panel layout tool (group boxes etc) 1. Click within the panel layout tool (but not on any button or other tool) 2. A red outline surrounds your selection - use this to identify that you have the correct tool selected 3. Click and drag the panel layout tool to a new location It is not possible to move a group box to between other group boxes. Instead it should be moved above or below the other group boxes which can then be shuffled further to achieve the desired position. To delete an item Right-click on the item and select Delete from the context menu. To copy an item Drag and drop the item while holding down the [ctrl] key on the keyboard. Release the item before releasing the [ctrl] key. Many tools will have similar properties so creating one button, defining its properties and then copying it can be a very efficient way of creating a tagging panel. 8.3.2 Modifying properties Items which have been added to the Taggin g E ditor have their appearance and function modified by changing properties in the Properties pan el. There are two types of properties; properties which can take any value and properties which must take one or more fixed values. The methods for modifying these two types of property are described below: A complete description of properties can be found in the topic Properties list Modifying 'any' value properties. 1. Click on the tool. This will display the properties for that item. 2. Click and type in the second column of the properties list to add or modify values. Modifying 'fixed' value properties. 1. Click on the tool. This will display the properties for that item. 2. Clicking in the second column of the properties list will allow you to select a value using the buttons that appear. It is not possible to type values. One of two types of button are used: - selects or creates property values from a dialog box e.g. shortcut key property - selects property values from a drop down list e.g. style property In the example shown below these buttons are shown as they would appear in the properties panel. Properties such as Sh ortcu t Key, Preroll and Trigger are selected using . Properties such as Style are selected using , and properties such as Category, Valu e and L abel are typed. - Version 6 - © Dartfish. All rights reserved. 158 Dartfish User Guide Double clicking the property heading in the column on the left is a shortcut to editing properties. 8.3.3 Planning a tagging panel Example of a basic Taggin g Pan el: Which events do you want to tag in your sport? Creating tagging panels requires a clear idea of what you want to tag and how you want to define the events' durations and the keywords which describe them. One definition of an event could be "a segment of video". You need to decide what are the different types of video segments that you want to denote. Those events are likely to be key moments or highlights within the video. © Dartfish. All rights reserved. - Version 6 - Tagging Video 159 Many events in your sport or activity are easy to define but perhaps others are less easy, consider this example: In soccer, ball possession in the opponent's half is a key moment that might be tagged as an "attacking possession". That possession might end in an attempt to score. So do you want to tag two events (attacking possession and attempt) or one (attacking possession; outcome = attempt)? There is no right or wrong answer to this; your decision will be based on what you want to review; tagging this as two events gives you the capacity to choose whether to review attempts separately from attacking possessions. From this example it should also be clear that Dartfish allows you to tag events which coincide or overlap. Which of these events have a fixed duration (e.g. actions) and which are of variable duration (e.g. game phases)? Dartfish can create 2 types of event. 1. Those where the duration can be predicted so only require a single button click to create an event with fixed duration. 2. Those where the duration of is not predictable and is defined by clicking a button on and then off. Regardless of how the event duration is defined, it is editable after creation. How will your events be categorized? The events list is a table made up of rows and columns. Each row contains the keywords which describe the event and at the top of each column there is a heading which describes the category of information displayed in that column. When categorizing events you may choose to simply list all events under a single heading such as 'Action' in the example below: Or you may decide that your events fall into different categories such as 'Set piece plays', 'Open play', 'Phases', 'Possessions' etc. Placing all events into a single category keeps things simple, but using different categories offers flexibility when it comes to filtering the events list and creating statistics. It is not possible to simultaneously create multiple variable duration events (i.e. those created using the continuous event tool) with the same category. If this is required, it is essential that different categories are used. For example, Team A might have possession but if there are to be different phases of play within that possession then these events should be categorized differently e.g. 'Phase' and 'Possession'. How will you describe these events? Events are described by assigning keywords to them. - Version 6 - © Dartfish. All rights reserved. 160 Dartfish User Guide Creating an event automatically adds 3 keywords; the video position, the duration of the event plus one user-defined keyword. Further keywords can be added to more completely describe the event so you need to consider what additional categories of information are needed. For example: 'Player' and 'Outcome' might be categories of keywords need to fully describe an 'Attempt' event. What Keywords are required for all events? It is very common that you will be tagging or reviewing the tags from more than one video file as described in the topic The Library. In this case the same keyword should be added to all the events of each file to allow you to easily distinguish which events belong to which file. For example, if you create 2 video files for the first and second half of the soccer game, it would be a good idea to have a category in your events list headed 'Game period', containing the keywords '1st Half' and '2nd Half' to allow you to distinguish between events which took place in the first video file and the second. Ready to start creating a tagging panel? Having thought carefully about the questions above, you will have a list of events and a list of keyword categories. No doubt you have also have some ideas about the keywords which should go into each category. Now you are ready to turn those ideas into a tagging panel. 8.3.4 Panel layout tools Group boxes These tools organize the layout of a panel by grouping buttons together. So unless you have a very simple tagging panel, group boxes are likely to be the first tools that you will add to a new tagging panel. They have two functions: 1. To organize the layout of buttons on a tagging panel. 2. To set the category property of many buttons simultaneously i.e. tools placed into a group box inherit their category from it. This is an efficient way of ensuring the category property of buttons is not omitted or inconsistently applied. However it is possible to over-rule the inherited category simply by setting the property of the individual tools. If you have already read the topic Planning a tagging panel, you should have a good idea of what categories your events list requires. Start your new tagging panel by adding a group box for each category and set the category property of each to each one of your categories. Nesting group boxes It is possible to place group boxes inside another group box. In the example below, group boxes have been used to organize the layout of players on a soccer pitch. © Dartfish. All rights reserved. - Version 6 - Tagging Video 161 In this image, 'Players' is the selected group box and the red line indicates that it contains the other group boxes. Its category property is set to 'Players' therefore the other group boxes and any buttons placed in them inherit this. Tab group boxes The pages of a tab group box each behave like a group box, the contents of which are only seen when the tab of that page is selected. The advantages of a tabbed group box are: They are a very space efficient way of including many buttons on a tagging panel. Panels can be created to only show buttons which are relevant to the current event; simplifying the panel and guiding the user to appropriate tools. Use the trigger property of a button to automatically select a tabbed group box page. Examples of this method to display relevant buttons as they are required can be seen in most of the built-in tagging panels. Adding tabs to a tabbed group box In the tagging panel editor, new pages are added to a tab group box by clicking the last tab showing the new page icon. The new page displays the label [...] until an alternative label property has been set. Panel layout tool properties Property Des cription Label The text which is displayed on the tab. Visibility The visibility property is a way of concealing tagging tools when the user is not required to use them directly. Other tools can be used to trigger the contents of a hidden group box even when not visible. Orientation Defines whether the contents of a group box are stacked vertically or placed horizontally within a group box. Image An image can be placed as a visual label for the group box. It will be - Version 6 - © Dartfish. All rights reserved. 162 Dartfish User Guide resized to fit next to any text label Category 8.3.5 The category of a layout tool sets the category of any other tool it contains. Inheritance can be over-ruled by setting the category of individual tools Event creation buttons E ven t creation bu tton s are used to add events to the E ven ts L is t. The action of these tools is to create an event described by: Position - the timestamp of the start of the event in the video clip Duration - how long the event last for Keyword - the event is described by a single user-defined keyword. The event can be more fully described using Keyword addition tools after the event is created Name - the filename that will be used if the event is exported as a video clip. This will be the based on the event keyword but can be modified. Event buttons The difference between E ven t bu tton s and con tin u ou s even t bu tton s is how they define the duration. Event buttons are used to create events with a fixed duration e.g. a tennis serve might take around 5 seconds to prepare, deliver then witness the outcome. A single click on this type of event button records the event. Continuous event buttons Continuous Event buttons are used to create events where the duration cannot be predicted, e.g. a whole point in a tennis game or an attacking phase in soccer. This button is clicked "on" and "off" as the event starts and ends. Continuous events are also switched off by activating other continuous events with the same category property. For example, this allows you to define the change in possession from one team to another with a single click. This improves the ergonomics of tagging but it makes the categorization of continuous event buttons important: if two continuous events are to run concurrently then they must have different categories. Important event creation tool properties © Dartfish. All rights reserved. - Version 6 - Tagging Video 163 Property Des cription Label / keyword properties These properties define the keyword to be recorded in the events list. Where the keyword property is not set, the label on the button will be used as the keyword. By setting these properties to different values, it is possible to tag a different keyword to the text displayed on the button. Category property Defines the column of the events list where the keyword will be added. Without a category property the button won't record its keyword. Duration For event buttons only; this is the fixed duration of the event Preroll Defines the number of seconds before the button click that will be included in the event. For example when a shot is made, the button is clicked but you want to define the start of the event 10 seconds prior to this in order to see the action leading up to the shot. An event button with a 10 second preroll and a 15 second duration would define an event starting 10 seconds before the button click and ending 5 seconds after. Offset start For continuous event buttons only; the equivalent of preroll. A negative value defines the event start prior to the button click and a positive value defines the event start after the button click. Offset end For continuous event buttons only; defines the end of the event before or after the button click. These are the essential event button properties. Other properties are described in the Properties list topic. Other event creation tools The team grou p box tool and the Zon e tool can be used to create events by setting their Action property = event. However, their default action is as keyword addition tools. 8.3.6 Keyword addition tools Keyword addition tools are used to add keywords to an event. They do not create events. Keyword addition tools can be one of two types: Keyw ord tools - are used after an event has been created to add a keyword to that event only Pers is ten t keyw ord tools - are activated before an event and add their keyword as the event is created. They remain active until deactivated and so can be used to add their keyword to many events. Keyword button A Keyw ord bu tton assigns an addition keyword value to the last tagged event (or to the selected event in the Events List). Persistent keyword button The p pers is ten t keyw ord bu tton applies its value to all events which are tagged while it is active ("pressed"). - Version 6 - © Dartfish. All rights reserved. 164 Dartfish User Guide For example, in tennis the name of the server could be assigned to a persistent value button. All events created while that button is active will be tagged with the server's name. Persistent values can be very useful when the analysis consists of more than one video file. For example to allow you to differentiate between an event which takes place one minute into the "first half" and another which takes place one minute into the "second half". First and second half are the persistent value buttons in this example. Text box The text box tool is a persistent keyword tool that assigns a variable keyword based on text typed into the box. For example you might use this to include the name and date of the competition or information about the conditions, as illustrated below: Score panel The score panel is a persistent keyword tool that lets you record the current score of the game. Zone tool The zone tool is used to record where an event takes place based on where an image is clicked. The recorded keyword is the coordinates of the clicked position. The zone tool is further described in the Zone tool topic Important keyword addition tool properties © Dartfish. All rights reserved. - Version 6 - Tagging Video 165 Property Des cription Label / keyword properties These properties define the keyword to be recorded in the events list. Where the keyword property is not set, the label on the button will be used as the keyword. By setting these properties to different values, it is possible to tag a different keyword to the text displayed on the button. In the case of the textbox tool, the keyword property can be used to define a default text box entry. Category property Defines the column of the events list where the keyword will be added. Without a category property the tool won't record its keyword. These are the essential properties. Other properties are described in the Properties list topic. Other keyword addition tools The Team Manager, Team Group Box and Player List Selector can also be used to add keywords to events. Their use is described in the topicsTeam Manager tool and Team Group Box and Player List Selector 8.3.7 The Zone Tool The zone tool is used to record where an event takes place based on where an image is clicked. The keyword it adds is the coordinates of the clicked position on a grid. Using the zone tool 1. Set the image property: Any image can be used but it is not resized by Dartfish, so it should be created and edited at appropriate dimensions with image editing software before addition to the panel. 2. Define the grid: Field h eigh t and field w idth properties are used to define a grid e.g. a field width value of 3 would split a soccer pitch into three vertical sections or a field width = 100 would split an American football field into 1 yard sections. 3. Define the center of the grid: Field center X and field center Y properties are used to define the center square of the grid. When the zone tool is clicked, zones to the left or above the central zone record a negative coordinate, zones below and to the right record a positive coordinate. 4. Set the category: as with all tagging tools, the zone tool requires a category in order to be able to record its keyword in the events list. The image below shows the coordinates which are recorded when a zone tool with field height and width=3 and Field center X and Y=2: - Version 6 - © Dartfish. All rights reserved. 166 Dartfish User Guide Each zone has equal dimensions. For sports with playing areas where the zones are not equal it will be necessary to create a zone tool image which distorts the zones to equal sizes. The grid is invisible. If it is required, it should be defined on the image itself using image editing software. Event creation tool or keyword addition tool? By default, the zone tool is a keyword addition tool. It can alternatively be used to create events. To do this set the action property to even t and define preroll and du ration properties as for an event button. 8.3.8 Team Manager tool If you have many players or several different teams to tag, you can use the Team M an ager to store all teams and player names but then select only those players taking part in the game. The selected players can be represented on the panel by: A Team Grou p Box tool - can be linked to the Team Manager and displays buttons representing each selected player. A Player L is t Selector - can be used to select a single team and player from those stored in the Team Manager's database See the topic Team Group Box and Player List Selector to learn how to link these tools to a team manager. The Team Manager tool Very little needs to be done with the team manager during tagging panel creation. Simply add it to your panel; teams and players will be added after closing the editor. Setting the category property for the team manger is optional. If it is set then a keyword representing the selected team will be recorded when a player button is clicked. Team Manager databases The teams and players that you add to a Team M an ager tool are stored in a database file which is created automatically in the same folder as the tagging panel. However, you may want to use a database previously created by you or another Dartfish user. Use the Databas e E ditor tab of the tagging panel editor to select the database file that you wish to use. Each tagging panel can have only one database but have many team managers enabling © Dartfish. All rights reserved. - Version 6 - Tagging Video 167 selection from different teams and players. Adding teams and players Teams and players are added outside the editor as described in the topic Using the Team Manager Important Team manager properties Property Des cription Label Using a label helps to identify a team manger. This is useful when linking it to a team grou p box or when more than one team manger is being used. Category property The category property is not an essential property for a team manager. If used then a keyword representing the selected team will be added to the events list. These are the main properties to consider. Other properties are described in the Properties list topic. 8.3.9 Team Group Box and Player List Selector Team Group box A team grou p box is a group box to which buttons are added by selecting players from a linked Team M an ager as illustrated below. To simplify the layout of a tagging panel it is usually best to put a team manager on a separate page of your tagging panel from the team group box and other tagging buttons. During tagging most activities will not require frequent access to the team manager; perhaps only before the start of the game. Team group box buttons can add keywords or create events Team group box buttons are Keyw ord bu tton s by default. Set the Action property to define whether the buttons function as keyword buttons, pers is ten t keyw ord bu tton s , even t bu tton s or con tin u ou s even t bu tton s . - Version 6 - © Dartfish. All rights reserved. 168 Dartfish User Guide For example, a pers is ten t keyw ord bu tton might be used to tag the 'Server' to all the events created in a tennis game. Or player possession might require the creation of an even t or con tin u ou s even t. Player List Selector This tool allows you to select a single player from a linked Team Manager's database of teams and players. The selections you make are pers is ten t keyw ords : the keyword is added to all events created after a selection is made. A player list selector can add up to two keywords to the events list: A keyword representing the player added to the category set for the player list selector. A keyword representing the team added to the category set for the team manager. If the team manager has no category property set then only one keyword is added by this tool. Linking to a Team Manager A Team M an ager tool must be linked to a Team Grou p Box or a Player L is t s elector tool which will display the buttons. To do this, proceed as follows: 1. Select the team group box or Player List Selector. 2. Double click the Team M an ager L in k property to display the property editor window (as shown below). 3. Select the Team Manager to be linked; it is identified by its label and Id. 4. Click the Add button. The Team manager on the right is that linked to the team group box.

Category property Defines the column of the events list where the keyword will be added. Without a category property the tool won't record its keyword. Action Defines the button type used in a team group box. The default setting is keyword button but buttons can also be event buttons, continuous event buttons or persistent keyword buttons. Duration/Preroll If buttons are event buttons, duration and preroll properties should be set to define these features of the event. See the topic Event creation buttons to learn more about these button types. These are the essential properties. Other properties are described in the Properties list topic. 8.3.10 The Filename Template tool The Filen am e tem plate tool enables tagging panel creators to control the file name used to save recordings made when using live tagging. When the user clicks the button it sets the file name for the next video recording. To use a filename template: 1. Add a filename template tool to the tagging panel 2. Set the label property to indicate the function of the button 3. Set the File N am e Tem plate property to the desired file name The file name template property can be set to a variable value based on the selection from a Player L is t Selector tool. See the topic Using variable keywords to learn more. 8.3.11 Properties list By clicking on any item on the tagging panel workspace, its properties are displayed in the Properties pan e. The properties of each tagging panel element are used to alter their appearance and behavior. Most tools have 3 crucial properties which you should set: 1. L abel – the text that identifies what this tool does. 2. Keyw ord – the keyword that will be assigned to the event. 3. Category – the category to which the keyword will be assigned. Think of the category as being the column heading of the E ven ts L is t in which keywords will appear. (see Planning a tagging panel for help to plan the categories that you need).

Orien tation For a button this defines whether the image is displayed above or to the side of the label. Buttons, group boxes For a group box this controls whether buttons are laid out vertically or horizontally. Style Sets the color of a button All Buttons Properties which affect behavior: Category The category property defines the events list column All into which a tagging tool's keyword will be placed. Each tool inherits its category property from the group box in which it is placed. It is therefore an efficient way to categorize buttons of the same category by placing them in the same group box. Override the inherited category by setting the category property for individual tools. Keyw ord Defines the keyword which will be used to describe All event creation and the event in the events list. For buttons, the keyword addition tools keyword will automatically set to the same value as the label property, however it is possible to record a different keyword if desired. For example, the label might be an abbreviation of the keyword. Preroll Defines the time before an event creation tool is clicked that will be included in the event. Preroll ensures that you don't miss the start of the action. All event creation tools Du ration Duration is the duration of the event that will be tagged when this button is clicked. This time includes any preroll that has been set. If the event is not of fixed duration then a con tin u ou s even t button should be used to manually mark the beginning and end of an event.

Double clicking on the property title allows you to change that property. 8.3.12 Automating tagging Large tagging panels with many buttons present two problems to the user: 1. Many mouse clicks might be required to record an event, making it hard to keep up with a fast moving game 2. It becomes more difficult to locate the buttons you want to use. This topic explains properties and features which assist with these problems Re se t C ate gory property Tools with a reset category property can be used to deactivate other continuous event or persistent keyword buttons. When the tool is clicked, all other buttons with the specified category are reset. This behavior is equivalent to that of continuous event buttons (see the topic Event creation buttons) which automatically deactivate all other continuous event buttons sharing the same category, except that the reset category property will deactivate buttons from any other category that you specify. Be careful with spelling and use of spaces - the reset category you specify must match the category of the tools that you wish to reset. However the case used is unimportant. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 172 Trigge r property The trigger property is used to activate or deactivate other tools. This property specifically identifies which tools will be triggered by selecting them from a list selected from a list. Examples of the use of the trigger property can be seen in some of Dartfish's built-in tagging panels where clicking an event button triggers a page of a tab group box revealing keyword buttons associated with that event. For example, when a scoring event is tagged the trigger property could be used to activate the tab group box which contains a score tool. To set a trigger property: 1. Select the tool which will trigger other tools. 2. In the properties panel, double-click the property heading Trigger 3. In the trigger dialog (see below) select the tool which will be triggered. Tools are identified by both their label and Id; be careful to select the correct tool in the case where more than one tool has the same label 4. Click the Add button 5.

This can be useful because once you know which keys to press tagging can be much quicker. To set a shortcut key: 1. In the properties panel, double-click the property heading Sh ortcu t key 2. Type a shortcut key 3. Click the As s ign button. This must be done before clicking OK © Dartfish. All rights reserved. - Version 6 - Tagging Video 173 As you can see here; more than one shortcut key can be assigned; and any combination of keys can be used e.g. 'S' might be used for a home team shot and 'ctrl+S' might be used for an opposition shot. 8.3.13 Using variable keywords A simple macro can be used to generate a variable keyword or category for a tagging tool. Syntax $(Item_ID.property) Limitations Only keyw ord and category properties can be set with a macro. The exception to this is the Filen am e Tem plate Bu tton which can also have its Filen am e tem plate property set. Only a Player L is t Selector can be the source and only its category or keyword can be referenced. Example 1 - Personalized event buttons In the following example, a macro is used to personalize the keyword recorded by the event buttons: - Version 6 - © Dartfish. All rights reserved. 174 Dartfish User Guide The macro used to record these keywords in the above events list is, for example: Winner $(TeamListSelector1.Keyword) Example 2 - Filename Template tool Continuing the example above, if a filen am e tem plate tool (see the topic The Filename Template tool) has the following macro for its Filen am e tem plate property: Semi-final $(TeamListSelector1.Keyword) versus $(TeamListSelector0.Keyword) New files created by live tagging would be named 'Semi-final Pascal Bingelli versus Serge Ayer' 8.3.14 Saving Tagging Panels To save your tagging panel: Select File>Save (or File>Save As ...) from the menu bar of the Taggin g E ditor panel. It can be seen from this process that tagging panels are saved as files, stored independently of Dartfish software and the video file(s) being tagged. Therefore the important factor in choosing a file name and location for a tagging panel is simply that the user knows where to locate it. Because a panel is saved as a file it can be easily distributed to other tagging users, however the following items should also be distributed if they have been used in a panel: 1. The tagging database - if a team manager tool has been used a database file will have been created with the same name and in the same location as your tagging panel. It will have the following icon: 2. Image files - any images included on your tagging panel are referenced as external files © Dartfish. All rights reserved. - Version 6 - Tagging Video 8.4 175 Tagging video In essence, the basic tagging process is simple; you see an event, you click an even t button then you click keyw ord buttons to add further details. The features that you might find on a tagging panel are described in this section (see Using tagging panels) Tagging can be applied in the following ways: 1. Tag L ive - use this mode if you want to tag the action directly from a video stream, either as it happens or from a tape recording (play back mode). In either case you will be tagging and capturing video to your hard drive simultaneously. 2. Tag Video Clip - use this method if the video clip is already on your computer. In this case, your task is to playback the video clip, locate an event and tag. 3. M ixed taggin g - you do not always have time to fully and accurately define events as they happen, or you may miss events. In this case, you are able to combine Tag live and Tag Video Clip by playing back the video clip and editing/adding events after the game. The result is a list of E ven ts (displayed in the E ven ts L is t, see The Events List) which can be played individually or in sequence. Events can also be "automatically" created by importing them from "character separated value" (csv) files created by other applications, e.g. sport specific statistical tools or the Dartfish Easytag App for iPhone and iPad (see Importing events ). 8.4.1 Using tagging panels Opening panels Access to tagging panels is described in the topic The Tagging Panel. Tagging tool and feature summary Below is a summary of tagging tools that may be found on a tagging panel. However, Dartfish tagging panels are highly variable and versatile, if the use of the tagging panel you use is not obvious it may be necessary to ask for instruction from its creator. E ven t bu tton - clicked once to create an event with a fixed duration. Default color red. Con tin u ou s even t bu tton - appearance identical to event buttons but when clicked, it remains activated until clicked a second time. Used to tag events of unknown duration such as possession or phases of play. Keyw ord bu tton - keyword buttons add addition keyword to events. They are not used to create events. Default color blue. - Version 6 - © Dartfish. All rights reserved. 176 Dartfish User Guide Pers is ten t keyw ord bu tton - appearance identical to keyword buttons but when clicked, it remains activated until clicked a second time. Used to add a keyword to many events. Must be activated before events are created and remains active until clicked a second time. Text box - a persistent keyword tool which adds of a variable keyword to events as they are created. Score pan els - a persistent keyword tool which adds the current score to events as they are created. Team m an ager - Displays a variable set of tagging buttons in a Team Group Box according to which team and players are selected. Has buttons to enable addition of teams and players. Player L is t Selector - adds a persistent keyword based on the player selected. Tab grou p box - used to simplify the layout of a panel by grouping related buttons together. Click the tab to see the buttons; often selection of a tab is automated by the action of another button. Zon e tool - records the coordinates of where the image is clicked. Can be either used for © Dartfish. All rights reserved. - Version 6 - Tagging Video 177 event creation or keyword addition. File name template tool - used to set the filename of recordings made during live tagging. 8.4.2 Tag Video Clip mode Use this mode to tag video file already existing in the library - it has been imported from the camcorder or other storage media. Tag video clip mode is selected by clicking the button at the top left of the video display. Tagging a video clip principally consists of these steps: 1. Loading all the video clips to be tagged into the Tray (see the topic The Library in the Tagging workspace section) 2. Selecting Tag Video Clip mode 3. Finding the relevant position on the video clip (see below). 4. Tagging an event in the video clip by clicking on an event button on the tagging panel. 5. Adding further keywords to that event by clicking on keyword buttons. Finding the relevant position Compared with L ive taggin g where events must be created in real time and in order, tagging a video clip allows the user greater flexibility. There are many ways to quickly navigate the video clip find the positions where events take place: Drag the playh ead to quickly position the video clip. Watch the time information next to the playhead as you drag it. It can help you position the video if you approximately know when an event took place. Use the s peed con trol to fast-forward and/or fast-rewind the video. To do this, set the speed to values greater than 1 (or -1 for fast-rewind) and play the video. Whenever you see an event, either click on an event button or pause the video first, and then select the appropriate buttons to tag the event. Position the playhead to a previously tagged event and continue tagging from there. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 178 The way to do this depends on the tagging mode being used: In Tag Video Clip mode, click the event once to move the playhead to the start of that event In Play Events mode, double click the event then switch back to Tag Video Clip mode to continue tagging. The playhead remains at the position of the selected tagged event. When the action is too fast to tag as the video plays, the video can be quickly paused by tapping the space bar on the keyboard. Now add tags before tapping the space bar a second time to resume playback. 8.4.3 Tag Live mode Tag live mode allows you to tag while recording video from a live video stream. This allows tagging to take place during the game and be ready for analysis immediately afterward. Tag live mode is selected by clicking the button at the top left of the video display (see The Video Panel). The Tag live interface The interface is identical to the Video Recorder interface: Read the section Video Recorder: get video from DV tape camcorders in the Video L ibrary chapter to learn how to use it. Tag live process: 1. Click the Record button. The video clip starts being captured to your hard disk. The live feed is displayed in the Video Panel. Use the tagging panel buttons to tag events as they happen. In tag live mode it is not possible to tag without firs starting to record. 2. Tag an event by clicking an event button on the tagging panel. 3. Add further keywords to that event by clicking on keyword buttons. 4. Click Pause Recording (optional). You may wish to use this during parts of the competition of no interest to you; half time, injury stoppage, gaps between competitors etc. 5. Click Resume Recording (optional), to continue recording. Note that the pause/ resume recording does not create a new video clip. 6. Click Stop Recording at the end of the game. A new clip is saved on your hard drive and a thumbnail appears in the Tray. It takes practice before you are able to accurately tag all events as they happen. Start simply by tagging "important" events without adding too many additional values. Read the section Review & edit events to see how you can edit and/or add events after they have taken place. If tagging from the replay of a tape, a set of controls allowing control of the video camera appear on the video display. © Dartfish. All rights reserved. - Version 6 - Tagging Video 8.4.4 179 Using the Team Manager Adding teams and players Adding players and teams to the Team M an ager is not completed in the tagging panel E ditor but after the tagging panel has been created and saved. Buttons at the bottom of the Team M an ager allow you to (left to right) add/remove teams and players from the team manager. You may want to create more than one team if you tag several teams or squads but at least one team must be created before adding players. After adding teams and players, their properties (such as team/player name) may be altered by clicking the to the item to be edited. button next Selecting players Players are selected/deselected by 'ticking' the box next to their name. If the box is ticked, a button representing the player will appear in the team group box linked to this player manager control. Philippe has been ticked, so… … a button representing him appears in the team group box 8.4.5 Using keyboard shortcuts Using the keyboard to activate tagging tools can be much more efficient than using the mouse. Buttons which have a keyboard shortcut display it below the label; it is used simply by pressing the keys indicated. Keyboard shortcuts only work when the tagging panel is active. Look for a green line at the top of the panel and if the line is red, click anywhere on the panel to activate it. Score panels can also have keyboard shortcuts but they are not displayed - the tagging panel's creator can advise you. 8.4.6 Manual tagging Manual tagging is used to divide a video clip into a series of sequential s egm en ts ; the start of each new s egm en t defines the end of the previous one. E ven ts can be added to segments to identify moments within them. Markers belong to the event in which they are situated and inherit keywords and duration from it. In effect, there is a hierarchy where videos are tagged with segments and segments are tagged with - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 180 events. Typical use Manual Tagging can be useful to anyone who needs to divide a video into sequential segments. It is particularly intended for those who require a hierarchy of video content on dartfish.tv. To understand its intended use it may help to know its origins: Basic Tagging was created for The City of Lausanne Council to distribute video of council meetings on dartfish.tv. The segments are of each session and events are used to identify minuted details. However, Basic Tagging has obvious applications as a simple tagging tool for many other situations. Creating Events 1. Click the tagging panel's Select button and choose M an u al Taggin g from the menu 2. Click the N ew Segm en t tab of the tagging panel 3. Enter a label and a description. This information is used to describe the event when published to dartfish.tv 4. Events are defined by adding categories and keywords to the table. One event can be defined by many keywords. 5. When the event is fully described, click the Add button to create the event in the E ven ts lis t. 6. Repeat steps 3-5 to add further events. Each event added alters the previous event's duration so that each event ends as the next begins. Creating Markers 1. Click the N ew M arker tab of the scene tagging panel 2. Enter a label and a description. This information is used to describe the marker when published to dartfish.tv 3. Markers are defined by adding categories and keywords. 4. When the marker is fully described, click the Add button to create the marker in the E ven ts lis t. 8.5 Importing events You can create events by importing them from a .csv (character separated value) file provided that, when imported, the data contains a column of time-stamps representing the position of each event. This will be useful to the following groups: Those using the Dartfish EasyTag App for the iphone, iPad and iPod. EasyTag allows you to create events using a similar tagging panel to those in Dartfish software, then export the results as a .csv file. Those sports that already use data logging software which creates statistics but does not relate the event to video or allow visual analysis. If this software can create a CSV file then the results can be imported into Dartfish. To import events 1. Pause the video or set the cue in to an easily distinguishable moment in the video. Doing so will simplify the synchronization of data and video. This can be one of the following possibilities: © Dartfish. All rights reserved. - Version 6 - Tagging Video 181 The moment representing zero time on your imported data. For example, if you started your EasyTag timer at the start of the game, pause the video or set the cue in at that point. An easily identifiable tagged event 2. Select Im port E ven ts ... from the Im port/E xport button located in the E ven ts lis t toolbar. 3. Locate and open the .csv file. The Import Events wizard then opens. 4. Choose the delimiters which separate each column of data in the imported file. If unsure, experiment with the various choices remembering that more than one delimiter might be used. The data preview will reveal when your data is successfully separated into columns. 5. Select which column in your data corresponds to Pos ition . Optionally, columns representing the du ration and n am e category can also be selected if the data contains them. 6. Select the time format used in the imported data. The preview shows the original data in brackets next to the time interpreted by Dartfish according to the selected time format. For example, EasyTag creates timestamps in the format hh:mm:ss; if this format is not selected the times shown in the position and duration columns will be "0" or appear very obviously wrong. 7. Decide which categories and events to import by ticking or unticking the headings at the top of each column and side of each event. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 182 8. 8.5.1 Select how the imported data is to be synchronized with video. The method depends on the choices made in step 1 and are described below. Synchronizing imported events Imported data is synchronized with video by specifying a time in the timeline of the imported data and then offsetting that to a matching position in the video denoted by one of the following: the start of the video clip, the Playh ead position, the Cu e-in m arker position. Consider the following examples: Synchronizing the zero time of data with video The simplest case to synchronize is when the timer of Easytag or your data logging software is started at an easily identifiable moment that is shown in the video. For example, the kick-off in a soccer game as illustrated below: To synchronize data in this case: 1. Before import set the Playh ead or Cu e-in marker to the video position where the timer started (unless video recording started synchronously with the timer). 2. During import leave the data position at 00:00:00 and select which video position that corresponds to. © Dartfish. All rights reserved. - Version 6 - Tagging Video 183 Synchronizing an imported event with video In the case that time zero for the imported data is unknown or otherwise not possible to identify on the video, you can synchronize the position of an event with video. To import synchronized events: To synchronize data in this case: 1. Before import set the Playh ead to the position of the event that you will use for synchronization. 2. During import select the event in the data 3. Select data offset of the selected event from the drop down list (see below) 4. Select the Playh ead option for video position. Synchronizing events after import Synchronizing events, or adjusting synchronization, after import can offer more versatility than synchronizing during import. For example, it is possible to give a different offset to different types of event. How to adjust position and duration of events is described in the topic Editing event timings Synchronizing modifies the time stamp for all events. It is therefore important that the time coding on your data remains comparable with that of the video. This means that if you - Version 6 - © Dartfish. All rights reserved. 184 Dartfish User Guide pause the Easytag or data logger timer during time-outs you also have to simultaneously pause video recording or vice versa. If you record the game as multiple video files you will have to import the events of each file as separate imports. For convenience it is best to record both video and the timing of events continuously and for as long as reasonably possible during the game. 8.5.2 Quick Import Qu ick Im port is a tool allowing you to quickly repeat an import using exactly the same settings as previous imports. To use Quick Import, proceed as follows: 1. Set the Playhead or Cue-in marker to an offset position. Remember that the same offset settings will be used as previous imports. 2. Select Quick Import... from the Import/Export menu located in the Events list toolbar. 3. Locate and open the .csv file. 4. The data is imported. If Quick Import is used when no previous imports have been made then the full Im port E ven ts options will be displayed (see the topic Importing events). 8.6 Review & edit events Play E ven ts mode is used to review and edit tagged events. To use play events mode you click the Play E ven ts button on the m ode bar above the video display. If it is not already displayed you also need to open the E ven ts L is t by clicking the E ven ts L is t button 8.6.1 on the view s bar above the video display . Selecting events from the Events List Selecting and playing events Sin gle click selects the clip - use the playback controls to play it. Dou ble click selects and plays the clip. Sorting events Events may be sorted by clicking any of the category headings. List Overlapping Remember that events can overlap. For example, in soccer a shot at goal event will overlap © Dartfish. All rights reserved. - Version 6 - Tagging Video 185 with a goalkeeping event. This button displays events that overlap with the currently selected event. Selecting multiple events By selecting more than one event you can indicate which events in your events list you want to play, edit or delete. Selecting several events is possible by the following methods: 8.6.2 1. Select several isolated events – hold down the control [ctrl] key on the keyboard and click each event in turn. 2. Select a group of sequential events – click the first event in the group then hold down the shift key and select the last event in the group. 3. Select all events – click any event and then use the keyboard shortcut ctrl + A Editing the event Editing keywords An event's keyword information can be added to or changed in 2 ways: Method 1: Use the tagging panel – when an event is selected in the events list, its keywords may be changed using the tagging panel's keyword addition tools. Method 2: Click the right mouse button while pointing at the keyword to be changed and choosing E dit from the quick menu. A new keyword may be typed or selected from a list. Selections of multiple events can be edited simultaneously using either of these methods 8.6.3 Editing event timings To edit position and duration using the time line The following method allows you to make modifications by selecting a start and finish point for the event in reference to the video. 1. Activate the M axim ize play ran ge function in the Timeline to zoom in on the event. 2. Click on an event in the E ven ts lis t. The event corresponds to the play ran ge; the pale blue area between the Cu e In and Cu e Ou t point. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 186 Drag the Cu e In and Cu e Ou t points to modify the event's position and duration. M axim ize Play Ran ge view immediately readjusts making it appear that nothing has changed but note the new position or duration displayed in the E ven ts lis t. To edit position and duration using the events list 1. Select the events to be modified. 2. Click the right mouse button while pointing at the duration of one of the selected events and choosing E dit from the quick menu. 3. Edit the existing time or type a new one. 4. Press the enter key to confirm the change It is not necessary to enter a new duration in the full time format displayed. Simply entering the value '10' would set the duration to 10 seconds. To adjust timings using the events list The video position of a single event can be modified as described above but when timing of position or duration require adjustment it is possible to add or subtract time in the following way: 1. Select and edit events as described previously 2. Key a + or - in front of the new value depending on whether time is to be added or subtracted For example, entering +5 would add 5 seconds to the selected times; entering -1:30 would remove 1 minute 30 seconds; and entering +1:25:00 would add one hour and twenty-five minutes. If unsure about how to apply the correct time format, simply edit the existing value and place a + or - in front. 8.6.4 Hiding unused categories The E ven ts L is t continues to display categories used by previous tagging projects even if they are not used by the current tagging session. The categories may be removed from the events list by: 1. Right clicking any column heading, and 2. Choosing Res et colu m n s from the quick menu that appears. © Dartfish. All rights reserved. - Version 6 - Tagging Video 8.6.5 187 Reviewing events and video during live tagging When using Tag Live mode it is possible to replay video while continuing to record. This will allow you to: Tag events that were missed and edit incorrectly tagged events Review the action to make informed coaching decisions during the game To review video 1.Click and drag the Playh ead to the position on the time line you wish to review. 2.The recorded video plays from this point but the video display controls can be used to control playback frame-by-frame etc To review an event 1. Click the event in the Events List to select it 2. The Playhead jumps to the start position of the event on the Timeline It is not possible to enter Play E ven ts m ode while continuing to record Returning to viewing live The Live tagging video display controls has a Live button which returns the playhead to the end of the timeline i.e. the live view 8.7 Filtering and viewing statistics Tagging will typically result in a long list of events. Locating particular events or analyzing their frequency using the events list alone would be a difficult task. There are three methods for searching for events: Table filter The table filter cross-references two keyword categories resulting in a matrix of frequencies. This can be used both to filter and to generate statistics. The table search is described in the following topic. - Version 6 - © Dartfish. All rights reserved. 188 Dartfish User Guide Simple filter The events list toolbar has a simple filtering tool which displays events based on an inputted value. The results of the simple filter can be further refined using the Keyw ord filter. Keyword filter The search pane is located on the left side of the E ven ts lis t and gives access to both the keyword search and the table search. To execute a keyword filter 1. Select the Keyword tab of the search pane 2. Click a keyword to select it. The events list immediately displays events matching the selection. 3. Select additional keywords by holding down the ctrl key as keywords are clicked. When keywords within the same category are selected they behave as an AND search but when selected from different categories an OR search is the result. The following example would show shots off goal and on goal by player Lemma. Combined filter The results of the simple filter and the keyword filter combine. For example, the keyword search above could also be carried out in the following way: © Dartfish. All rights reserved. - Version 6 - Tagging Video 8.7.1 189 The table search The search pane is located on the left side of the E ven ts lis t and gives access to both the keyword search and the table search. To create a table search: 1. Select the Table tab of the search pane 2. From the drop down lists at the top of the pane, choose the two categories to cross reference. 3. A frequency matrix is created as shown below. Filtering using a table search Clicking each figure and heading of the resulting table filters the events list to match your selection 8.7.2 Undo searches Searches reduce the event list to displaying only search results. To see all events, click the s h ow all button above the events list. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 190 8.8 Producing & sharing tagging resources Having tagged a video you may want to share that work with others. It is easily possible to share: Game video complete with tags Individual events - as separate video clips or as a compiled highlights video. The even ts lis t - can be exported as a .CSV file The taggin g pan el - tagging panels are saved as files. To give others access to your tagging panel, simply give them the file. They use the Create E ven ts pane to open the tagging panel. Dartfish offers the possibility to publish to a range of outputs including CD/data DVD and online to your own FTP site or to Dartfish TV; our own media sharing platform (see www. dartfish.tv). To get a more comprehensive view of publishing from Dartfish see the Dartfish outputs - publishing & sharing chapter. 8.8.1 Sharing game video There are two possibilities depending on whether you want to share tagged or untagged video 1. Share Video Clips from the Tray the .dartclip file for each clip. The dartclip contains events list data so this is the best method to share video with other Dartfish users. Of course you can also Sh are match video with non-Dartfish users but if you want them to see tagged events it would be better to use the method below. Learn more about sharing video clips from the Tray and all the possible output destinations in the Publishing and Sharing chapter. When dartfish.tv is chosen as a sharing destination, video but not events are shared. 2. Publish from the E ven ts L is t - send video and events to Dartfish TV where it can be viewed by all who have access to your channel. © Dartfish.

Publishing Wizard step 3 - video selection Choose which of the Tray's contents are to be shared. 8. Publishing Wizard step 4 - select which events are to be displayed with the published video. Filtering or selecting in step 2 may make this easier. 9. Publishing Wizard step 5 - content categorization Some categorization will be done based on the keywords assigned to video (see Organizing your Library in the Library chapter). In this step you can add further keywords to help others find videos that you publish. Some information is mandatory as defined by the channel administrator. - Version 6 - © Dartfish. All rights reserved. 192 Dartfish User Guide 10. Publishing Wizard step 5 - define publishing options: © Dartfish. All rights reserved. - Version 6 - Tagging Video 193 Here you can define: What is viewed on the Dartfish TV platform - rather than the full video a shorter trailer can be played to help viewers decide what to download. What quality of video is available for download - it is possible to define a higher quality for offline viewing. Attachments - the tagging panel, a statistics analysis spreadsheet or any file can be attached and downloaded with the video. To use tagged video downloads from dartfish.tv (dartfish users) Dartfish users can use tagged video from Dartfish.tv. To do this: 1. Download the video clip from dartfish.tv from the downloads section of the video document 2. Download the .dartclip data file from the attachments section to the same folder as the video. 3. When the video is opened in Dartfish tagging, the events will appear in the events list To use tagged video downloads from dartfish.tv (non-dartfish users) Non-dartfish users can download tagged video but should use the download to Dartfish Player option to be able to view events off-line. 8.8.2 Publishing events Events can be shared independently of the entire game video in 3 ways: 1. Publish them as individual video clips - a selection of events can be directly burned to CD or published as new video clips. Then you might insert the newly created video clips into video editing software to create motivation video with transition effects and music. Or they can be loaded in the Tray, saved as a Playlis t and are ready to be presented to your team. The presenter only needs to know the basic playback functions of the Player. 2. Publish a highlights movie to Dartfish TV - a compilation movie of selected events which can be viewed by all who have access to your channel. 3. Export them to the Analyzer Storyboard - here they can be annotated and published using the powerful tools of the Analyzer. This is explained in detail in the topic Storyboard. To Publish events as new files 1. Select events in the E ven ts list and click the Pu blis h E ven ts button. Multiple selections can be made by holding down the CTRL key while clicking each event. 2. Select Pu blis h E ven ts ... Video clips can be published to three different destinations, as illustrated below: - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 194 1. M y Com pu ter - a new video clip of each selected event is created. Video quality can be left unchanged (applies to .wmv, .avi and .mpeg video settings). In the last step of the wizard, you have the option of generating a Playlist of the newly created video clips. Select a destination directory, enter the name of the Playlist and click on the Save button. A Playlist with the file extension *.playerproject is created. It contains links to the new video clips. You can open this Playlist in the Tray and present it to your team using the Player. 2. Recordable CD or DVD or E n h an ced Recordable CD or DVD - selected clips are burned on a CD. Read Sharing video files in the Video L ibrary chapter to learn about these two destinations. To publish a highlights movie on Dartfish TV 1. Perform a search to Select events in the E ven ts list and click the Pu blis h E ven ts button. Multiple selections can be made by holding down the CTRL key while clicking each event. 2. Select Pu blis h H igh ligh ts ... to launch the H igh ligh ts Pu blis h in g W izard. 3. Wizard step 2 - Select which videos you wish to share. "Check" those to be shared as shown below or click the Select All button: 4. Wizard Step 3 - provide additional information to aid those browsing your channel or performing keyword searches for similar movies: © Dartfish. All rights reserved. - Version 6 - Tagging Video 195 Keywords are searchable terms that link movies of similar types on your channel. The tagged keywords for each event are used as keywords so it is only required to provide additional keywords. 5. Wizard step 4 - Attach related documents and define offline viewing preferences. Some channels allow download of video for viewing offline. Set what quality of video is to be used remembering that higher quality will take additional storage space and encoding time. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 196 Attached documents can be any file you wish to be associated with the video. They are downloaded with video files. This is the final step before processing and upload of files to Dartfish TV. 8.8.3 Adding notes to events Text notes can be added to events. To do this, proceed as follows: 1. Click the event with the right mouse button 2. Select Properties from the quick menu 3. Edit the notes section of the general tab Using event notes will be principally of interest to contributors to dartfish.tv where notes will be easily viewable as event marker notes. 8.8.4 Storyboard Storyboard - selected events can be "transferred" to the An alyzer module and analyzed as any other Storyboard item. In many ways the Analyzer's Storyboard is the best presentation and publishing tool for the following reasons: Analyzer zoom and drawing tools can be used to help illustrate and explain. The Storyboard can be presented using the remote control in the same way as the events list. But with the advantage that a selection of many events from different searches can be compiled in the storyboard. The Analyzer offers additional outputs such as the Mediabook and Analysis Recorder. To add events to the Storyboard: 1. Select events in the E ven ts list and click the Storyboard button . . 2. Select the range of events to be exported. Each selected event creates a new storyboard item. The process of selection and adding events can be repeated until the Storyboard contains all the events to be presented.

Your selection is exported in a CSV file which can be opened in spreadsheets and databases to analyze statistics and create graphs. You can also use such files as backup copy of your tagging work. Such a file can be imported later and re-synchronized to the video (see Importing events). - Version 6 - © Dartfish. All rights reserved. Chapter IX Displaying metadata from external devices 200 9 Dartfish User Guide Displaying metadata from external devices Dartfish's Analyzer and InTheAction modules support the display of data from other software applications. For example, timing devices, heartrate monitors or power measurement devices that use sensors linked to software can use Dartfish's Metadata toolkit to send the processed data to Dartfish Software. Such metadata adds to the interpretation of video images by relating them to the effort of the performer. Throughout this tutorial, the term "metadata" will refer to data (in a broad sense) generated by entities external to Dartfish Software and captured by Dartfish Software while capturing a video clip. Examples of such metadata are heart rate, speed, etc. It is assumed here that you are already familiar with the use of InTheAction (see xxx) and the Analyzer (see xxx). To display metadata on Dartfish video images need to: Activate advanced options supporting metadata capture and display. Use the InTheAction module to capture metadata streams while capturing related video images. Link drawings superimposed on video displays to metadata values. Use the Analyzer module to replay previously captured video with related metadata. This tutorial covers how to do this and additionally how the Drawing Libraries can be used to make the display of metadata. You will also learn how to display metadata values graphically next to video images. 9.1 Support for metadata in Dartfish Software For data from external software and devices to be displayed in Dartfish it is obviously not as straightforward as connecting the device Metadata can be captured and displayed. These tasks are performed using 2 modules: InTheAction module, for capturing video clips and metadata synchronously. Analyzer module, for displaying metadata and performing some analysis. Apart from these 2 modules, there is no support for metadata. For example, it is not possible to display metadata with the Player. In these 2 modules, the metadata features are enabled by advanced settings that are available in the "Options" dialog (Advanced Options). © Dartfish. All rights reserved. - Version 6 - Displaying metadata from external devices 9.2 201 Setting Advanced Options To use (capture and display) metadata in Dartfish Software, 5 advanced options can be enabled. These 5 options are devided into 3 groups: Metadata group - Capturing, saving and displaying metadata (not in the video). Metadata overlay group - Using overlays on the video to display metadata on the video. Overlay drawing repository - Enabling Drawing Library for defining several video overlays that can be selected during video capture. In Dartfish Software, these different options are accessed in the "Advanced" tab under "Options" menu item in "Tools" menu ("Options" dialog can also be directly accessed by depressing the "F3" key). These options are shared amongst the "Analyzer" and the "InTheAction" modules. The figure below depicts the different options as they are displayed in the "Options" dialog (they have been highlighted in the picture): - Version 6 - © Dartfish. All rights reserved. 202 9.2.1 Dartfish User Guide Analyzer Advanced Options Load embedded drawings - this option allows the analyzer to load the drawings (if any) that have been saved with a video clip during its capture. If this option is disabled, the Analyzer will only load the video (and possibly the metadata if the "Display metadata viewer..." option is enabled). In order to save drawings with a video clip, the advanced option "Save currently selected overlay drawing with the video clip" must have been enabled in the InTheAction (ITA Advanced Options) prior to saving the clip. Display metadata viewer for allowing metadata analysis – this option belongs to "Metadata group" and must be enabled for the Analyzer module to display the metadata graph under the videos. 9.2.2 InTheAction Advanced Options Receive, record, and save metadata - this option enables the InTheAction module to receive, record, and save metadata with the video clip. Save currently selected overlay drawing with the video clip – when enabled, the drawing that is currently displayed in Live or Replay mode is saved with the video clip at the end of the capture when the user saves the video clip. The drawing can later be automatically loaded and displayed in the Analyzer (if the "Load embedded drawings" option is enabled). Use Drawing Library – the Drawing Library stores up to nine different collections of clip drawings (see specific section later in this document). When this option is enabled, the library is used for managing the drawings in the InTheAction module. T his opt ion a lso displa y s a ddit iona l t ools on t he InT he Ac t ion le ft t oolba r. 9.2.3 Section summary In this section you have learned which options you need to activate to be able to display metadata. You are now ready to capture metadata and video images simultaneously using DartFish's InTheAction module. 9.3 Capturing & displaying Metadata with the InTheAction The InTheAction module is used for recording Metadata (it is currently not possible to use the DVImport module to record Metadata). The "Receive, record and save metadata" advanced option must be enabled (Advanced Options). When receiving external data, the InTheAction module automatically creates a data source stream for each received data stream. These data source streams are created automatically as the data is received. This has the following important consequence: no da t a sourc e st re a m s a re a v a ila ble unt il Da rt fish Soft w a re ha s re c e iv e d som e da t a. The current values of the metadata streams can be displayed in InTheAction's Live © Dartfish. All rights reserved. - Version 6 - Displaying metadata from external devices 203 mode (see Displaying Metadata in Live Mode). Even if the metadata is not displayed on the video in Live mode, the metadata streams are nevertheless recorded with the captured video clip but only if t he a dv a nc e d opt ions for re c ording t he m e t a da t a ha v e be e n e na ble d for the InTheAction module (ITA Advanced Options). 9.3.1 Checking that Metadata is received The list of data source streams and their properties can be displayed in InTheAction. Select the "Manage metadata repository" menu item in the left ITA toolbar as follows: Note: if this menu is not displayed in the left toolbar, you have to enable it in the advanced options (see InTheAction Advanced Options). The following data source list dialog is displayed showing the different data sources and their metadata streams. The content of this dialog content is not automatically refreshed. When this dialog is left opened and new metadata streams are detected by Dartfish Software, you must depress "Refresh" button to update the dialog list view (or close the dialog and reopen it). In this example, 2 data source streams have been received: "Heart Rate" and "Spin Amount". The "Heart Rate" data stream has integer values (e.g. 123, 150). The "Spin Amount" data stream has float values (e.g. 12.34, 0.34E-2). - Version 6 - © Dartfish. All rights reserved. 204 Dartfish User Guide All data source streams that are displayed in the DataSource List dialog are recorded with the video clip. Currently, it is not possible to select which data source stream will be recorded with the video. If no data source streams are displayed this indicates that the Dartfish Software has not received any data yet. The list of received metadata streams is not saved when quitting Dartfish Software. 9.3.2 Displaying Metadata in Live Mode Metadata stream values in the InTheAction module are displayed with overlay drawings that are drawn on the video image. First check that data source streams have been detected (as explained in Checking that Metadata are received in InTheAction). Switch the InTheAction module to Live mode. Select the Source drawing (usually this is the default setting): Depending on the type of data contained by the data source stream, you must select the appropriate drawing tool. For integer values, select the "Text" drawing tool. For float values, select the "Text" or "Graph" drawing tools. For vectors with origin (Vector6) data type, select the "Force Meter" drawing tool: Note: if this menu is not displayed in the left toolbar, you have to enable it in the advanced options (see Advanced Options). Note: drawings can be resized on the screen using different handles that depend on © Dartfish. All rights reserved. - Version 6 - Displaying metadata from external devices 205 the type of drawing. "Force Meter" drawings also offer a yellow handle for resizing the length of the displayed moving arrows. Draw on the video using one of the drawing shapes selected in the previous step. Select the shape and right click on it to display a popup menu. Select the menu item "Metadata Properties..." as below: If this menu item is grayed, no data source streams are available or no compatible data source streams are available. The following dialog is then displayed: To assign a data source stream to the current drawing, click on "Linked to the following Metadata source" option button and select the targeted data source stream using the 3 list boxes. If the "Linked to the following metadata source" option button is disabled (grayed) then it is not possible to assign a data source stream to the drawing (there are no compatible data source streams currently available). - Version 6 - © Dartfish. All rights reserved. 206 Dartfish User Guide The drawing shape displays the value of the linked metadata stream. For example, a "Text" drawing displays a value and a graph drawing displays a graph. 9.3.3 Section summary In this section you learned how to capture metadata with a video clip. This metadata can be displayed in the Live mode by linking drawings to the metadata stream. The next section will cover how to use the Analyser module to display metadata on previously captured video and display metadata graphically. 9.4 Using Metadata in the Analyzer The Analyzer module is used for observing and comparing stored video clips and their recorded metadata. When a clip is opened in the Analyzer, any recorded metadata can be displayed in a graphic view as below: The tree view on the left side of the graphic view and its associated small tool bar are described in the following chapters. When multiple clips containing metadata are opened, the metadata corresponding to each clip is displayed in the graphic view. Each graph is color-coded with the corresponding color of each clip's timeline. For example, the yellow graph corresponds to the yellow clip in the timeline. © Dartfish. All rights reserved. - Version 6 - Displaying metadata from external devices 207 The graph part of a video clip is synchronized with its timeline. For example, in the graphic view above, shifting the yellow timeline to the left will also move the yellow graph. 9.4.1 Displaying Metadata diagrams Metadata stream values can be displayed in the Analyzer module as a graph synchronized with the timeline: Proceed as follows to display metadata graphs in the Analyzer: Enable the "Display metadata viewer for allowing metadata analysis" advanced option (Analyzer Advanced Options). Display the graph part by clicking on the graph button on the Analyzer left toolbar (by default the graph part is hidden): Note: if this button is not displayed in the Analyzer left toolbar, you must enable some advanced options (Analyzer Advanced Options). Open a video clip in the analyzer. Any metadata previously captured with the InTheAction module is displayed in the graph part of the analyzer under the timeline. The different buttons in the graph toolbar alter the way the graph is displayed. The button displays simple statistics such as min, max and average values. The In and Out points act as delimiters for these calculations. The button displays the data value corresponding to the value at the cursor position in the timeline on the top right corner of the graph. (e.g. –9.72 and –2.00 in the picture above). - Version 6 - © Dartfish. All rights reserved. 208 Dartfish User Guide The button displays the name of the currently displayed metadata stream in the top left corner of the graph (e.g. "Channel 1" in the picture above). The button toggles between single or multiple clip display. When multiple clips are simultaneously opened in the Analyzer, the graph can display the metadata from a single clip or from multiple clips. In this latter case, the each clip's metadata curve is the color of the corresponding clip's timeline. . For example, the data curve corresponding to the clip that has the yellow timeline is displayed in yellow. In single clip mode, the user can switch between the different graphs for each clip by selecting the clip in the Analyzer (usually done by clicking directly on the targeted clip video). The button switches between "superimposed" or "separate" mode when multiple clip curves are displayed. This feature is only useful when graphs from several clips are simultaneously displayed. In the "superimposed" mode, the graphs of the different clips are superimposed on each other. In the "separate" mode, the graphs are displayed as separate graphs, each in its own display area. The button toggles between the "all clip" and "single clip" data stream browse mode. These 2 modes alter the way data source streams are selected in the tree view to the left of the graph. The graph is fully synchronized with the timeline. So, if one of the clip is moved on the left by dragging its timeline on the left (by click and dragging the yellow © Dartfish. All rights reserved. - Version 6 - Displaying metadata from external devices 209 timeline), the corresponding graph is also moved accordingly. The graph is also zoomed in and out as the timeline is zoomed in and out. 9.4.2 Displaying Metadata on the Video Proceed as previously explained for the InTheAction - Displaying Metadata in Live Mode. 9.5 Using the Drawing Library The Drawing library is a source for different collections of drawings that can be displayed on video clips. To use it, it must be enabled in the InTheAction advanced Options. It is used to store and recall different sets of drawings which can be used to assist with analysis and removes the need to redraw. Strictly speaking, the library is not linked to any metadata features but it can be used to memorize the position of drawings that can be later linked to metadata streams. The Drawing Library allows the following features: Define sets of drawings that are saved (persisted) between each session in Dartfish Software - All the drawings in the Drawing Library are saved when the user quits Dartfish Software. The next time the user launches Dartfish all the drawings in the library are immediately available as soon as the InTheAction module is enabled. Switch between the different collections of drawings --- a collection of drawings can be directly selected using the list box in the InTheAction left toolbar. It is also possible to map a remote control key for switching between the different groups of drawings. Manage the different groups of drawings by creating or deleting them. In future versions of Dartfish Software it will also be possible to export or import the groups of drawings between different Dartfish computers. The Drawing Library can contain up to 9 different templates. 9.5.1 Managing Overlay Templates The Drawing Library content is displayed by selecting the submenu item "Manage Drawing Library" as follows: The following dialog is then displayed: - Version 6 - © Dartfish. All rights reserved. 210 Dartfish User Guide All the currently available overlay templates are displayed in a list. The currently displayed overlay template is marked with the red/yellow icon on its left side ("Overlay #1" in the example above). The name of each overlay template is displayed in the "Name" column. With the current version of Dartfish Software, it is not possible to rename an overlay template. Clicking the "New" button creates new empty overlay templates. At most 9 of these overlay templates can be created. The name of the newly created overlay is generated automatically. Clicking the "Delete" button deletes the currently selected overlay template(s). Multiple selection of overlay templates is possible using the usual methods (clicking template names while combining shift and control keys). The currently displayed overlay template cannot be deleted. 9.5.2 Selecting the current Template When the overlay template library is enabled (InTheAction Advanced Options), the drawings that are displayed in InTheAction's Live mode are saved to the currently selected overlay template. This will be the template indicated in a list box on the left toolbar as shown below: The currently selected overlay template can be changed by selecting an alternative from the list box as follows: © Dartfish.

When this is not practical you can manually apply for an activation code: The process will generate a page of information that you can email or fax to Dartfish. You will be sent an activation code that you must manually enter. The activate process requires that you provide your licence code. This will have been provided with your software purchase and is different from the code for your Dartfish Software or any other readers you have purchased. Updating Data Readers Data Readers are not automatically updated by the same process as Dartfish software. If and when updates become available, those who have purchased a Reader will be notified by email. Alternatively, updates can be dowloaded from the Dartfish website. Video tutorials will give you useful guidance on how to use your CSV Reader. They can be accessed from the Start > Program s > Dartfis h > CSV Reader menu. 10.1.2 About CSV data The Dartfish CSV Reader can read a wide range of text file formats provided the following conditions are met: 1. The data can be separated (parsed) into columns which are delimited by a text character (tab, comma, semi colon, space etc) 2. The resulting table has no more than one row of column headers. Where condition 2 is not met, it is usually possible to open, parse and edit a text file in a spreadsheet program such as Microsoft Excel. By this method data can be rearranged and extra headings removed. The edited data should be saved as a .csv file rather than a spreadsheet file. The source This Reader names the source by the file name of the CSV file. Optionally you can input a source name of your choice. The streams The CSV Reader parses character separated data into columns, each of which represents a different da t a st re a m . You are able to select which of these columns - Version 6 - © Dartfish.

Such a file is called a Data Sou rce and is created by or exported from a device external to Dartfish (refer to the manufact urer's documentation to learn how to do this). A Data Source may contain multiple Data Stream s as illustrated in the following figure. The data streams are listed under the headings of their data sources: Caden ce, H eart rate, Pow er, Speed and Tim e are Data Stream s 10.1.3.1 Linking Data You can create links between one video clip and more than one data s ou rce. To establish a link, right-click a video file in the Tray or in the Item s L is t and select Link Data Streams from the context menu. © Dartfish.

All rights reserved. - Version 6 - Dartfish Readers 221 data in Dartfish or managing Data Sources etc. By default the file name of the Data Sou rce File is used but you can enter your own name or select a name which combines the file name with the current date. Separator - It is essential that your data is successfully parsed before continuing. To do this, select the character used to delimit the columns of your Data Sou rce. A range of commonly used separator characters is offered but it is also possible to type any character or combinations of multiple characters. If you are not sure which character has been used, experiment by selecting different characters; when successful you will see your data divided into separate columns as shown below: Use first row as headers - where data has a header row you must tick this option to prevent the headers being treated as data. If your Data Sou rce has more than one row of headers you must delete or merge the extra rows. You can do this by editing the file with text editor software or a spreadsheet such as Microsoft Excel. Hide comments starting with - the Data Source may contain text comments. Often these are marked by a specific delimiter. Exclude such comments by typing the delimiter character used. Manually set the file encoding - Dartfish automatically selects the file encoding used but if necessary you can manually choose from a selection of text encoding types. 10.1.3.3 Time Stamp The CSV reader must be able to relate each piece of data in a Data Stream to a position in the video. There may be a column of time stamp data in the Data Source but where this is not the case, a time stamp can be added at a fixed interval. Using data from the Data Source as the time stamp 1. Select the option "Data Source" from the Select th e tim e s tam p s ou rce list box. 2. From the Select th e tim e colu m n list box, select the column from the Data Sou rce that contains time values. 3. Select the Tim e Form at or units used. It is essential that the reader understands how to interpret time stamp data. For example, if the time stamp is "100" does this - Version 6 - © Dartfish. All rights reserved. 222 Dartfish User Guide represent 100 seconds or 100 milliseconds? Using Interval or Frequency as the time stamp The reader can create a time stamp at a fixed interval (seconds or fractions of a second) or at a fixed frequency (Hertz). This is useful if time stamps do not exist in the data source or are not in a time format recognisable by the reader. The use Interval or Frequency time stamp sources, Data Stream samples must be at regular, fixed intervals. 10.1.3.4 Selecting columns as Data Streams The Data Sou rce may contain many columns of data that you will not wish to link to video. You must indicate those that you want to link by selecting them as shown below: Dis tan ce an d s peed are th e s elected s tream s When you select a column, you will be prompted to set attributes for the data stream. Name - This is the name used to identify the Data Stream when using linked data in Dartfish. By default the column heading from the data source is used but it can be changed to a value of your choice. In the example above "xdist [ m]" will be replaced by "Distance". It is particularly important to set a name property for the Data Stream when no meaningful header is present in the Data Sou rce Type - Select either Number or Text. By selecting "Text", numbers will be treated as text and Dartfish will not attempt to plot them on the Data Graph. Unit name - This is a descriptor of the values of data in this data stream. It is displayed in the video clip Properties or in the E xtern al Data M an ager. © Dartfish. All rights reserved. - Version 6 - Dartfish Readers 223 After setting these attributes they can be changed by right-clicking the column heading. 10.1.3.5 Managing links To manage links between video files and Data Sou rces , right click the video file in the L ibrary . Select M an age th e data s tream s ... from the context menu. Removing the link You can remove the link between the data source(s) and the video file. To do this, select the data s ou rce and click on the U n lin k button. It is not possible to remove a single stream of a data source. Broken links A link can be broken when the external data source file has changed location on the disk or has been renamed. It also happens when the video clip is shared and opened on a different machine. As a result, the data cannot be displayed in the Analyzer any longer. To check for broken links right click the video file. Select M an age th e data s tream s from the context menu. Select the data source and its properties are visible on the right hand panel. If the link is broken the Availability property will read Sou rce M is s in g. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 224 To correct a broken link, click the Relin k button then browse for the new location of the data source. Synchronisation of data and video is retained provided that the Dartclip metadata file has also been moved to the new location of the video file (see Sharing Data for further information about Dartclip files). 10.1.4 Viewing data Dartfish's An alyzer M odu le is capable of displaying Data Stream data in 2 ways: 1. Text drawings, graph drawings and other specialist data drawings can be linked to data streams such that values can be displayed on the video image. Numerical data can be displayed with the Text and the Graph drawing tools, while text can only be displayed with the Text drawing tool. Below is an example of what it might look like. Notice the symbols left to the data: These symbols are letters of the Dartfis h Sym bol font (see Drawings for more information). 2. Using the Data Graph panel each n u m be r data s tream is represented as a different curve. The curves can be synchronized with the video. The Data Graph and Graph drawings can only display integer and floating point numbers. For example, times in the format hh:mm:ss etc will be treated as text and cannot be displayed. If you wish to graph times (e.g. split times) then you must first edit the Data Source to represent times as numbers. © Dartfish. All rights reserved. - Version 6 - Dartfish Readers 225 10.1.4.1 Synchronization You can quickly synchronize the data streams and the video in the Data Graph pane of the An alyzer, as illustrated below: To synchronize, proceed as follows: 1. Move to an appropriate position in the video clip. 2. Activate the synchronization mode by clicking on the Res yn ch button 3. Align the streams to the playhead (green arrow in the illustration) by click & drag of the streams to the left or to right. 4. Click a second time on the Res yn ch button once done. To synchronize precisely, you should position the video to a distinct instant where you might expect to see an obvious change in the data graph e.g. when the athlete starts pedaling. This can be easily matched, for example, to the cadence stream (see illustration above). 10.1.4.2 Drawings The data can be directly overlayed on the video image in the An alyzer. This is done by linking drawings to data from a Data Stream . The following is a representative but not comprehensive list of drawing tools that can be linked to data. Different devices will produce data which can be best represented by different types of drawing: Text tool: Use to display any value from a Data Stream. Using the Dartfish symbol font, the text tool can also be used to display data specific icons to label values (see below). Graph tool: Use to represent numerical data as a graph. Force Meter: Use to represent the magnitude and direction of a force (typically for devices producing this type of data). To link a drawing to a data stream (example using Te xt drawing): 1. Use the Text drawing tool to create a small text drawing. The text you type to create the drawing is not important e.g. "xxx". Be sure to finish editing the text before proceeding to the next step; to do this click on the video display outside the drawing. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 226 2. Right click on the drawing to display the context menu. 3. Select the E xtern al Data Dis play... option. 4. Select the Data Sou rce and Data Stream then click the OK button. 5. The text box now displays the value of the selected data stream. Don't forget to synchronise to make sure the displayed values have proper meaning. Displaying Dartfish explanatory symbols The Dartfis h CSV Reader provides the Dartfis h Sym bol font which you can use with the Text tool of the An alyzer or In th e Action modules. Using this you can substitute long names with self-descriptive symbols. See the Table 1 for the key mapping. Key © Dartfish. All rights reserved. Symbol (character) Description - Version 6 - Dartfish Readers S or s Speed P or p Power C or c Cadence (pedals) H or h Heart rate 227 The Dartfis h Sym bol font is automatically installed with the Dartfis h CSV Reader. 10.1.5 Sharing linked data In order for others to see linked data you have two options: 1. You can publish a movie from the Analyzer. This will include drawings that have been added to the video clip - including those displaying Data Streams. 2. You can share the video file and the Data Sou rce with other Dartfish users. Although the recipient will need to re-establish the link using their own CSV reader, synchronization is retained. 10.1.5.1 Publishing You can publish the video with overlayed data from the An alyzer (see Saving movies from the Analyzer to learn how to do this) as illustrated below: In this case, the result is a video that can be shared in your team. It does not require Dartfish to play it. You cannot embed the data in the video file (i.e. in the .dartclip metadata file associated with the video clip). The Dartfis h CSV Reader only creates a "live" link between both the data and video files. 10.1.5.2 Sharing data The Dartfis h CSV Reader does not embed data in the video file (i.e. in the .dartclip file associated with the video clip). It only creates a "live" link between the data and video files. Therefore if you wish to share video and linked data with other Dartfish users the following are required: The recipient must have Dartfish Software - Version 6 - © Dartfish. All rights reserved. 228 Dartfish User Guide The recipient must have the Dartfish CSV Reader add-on. You must provide the video clip, the Data Source file and (optionally) the Dartclip file as shown below. The recipient establishes a link using the Relin k function described in Managing links. Dartclip files store all additions made to video by Dartfish. These include details of external data links and synchronisation. If the Dartclip file has not been shared then the recipient must create a new link between the video clip and Data Sou rce. 10.2 Dartfish SRM Reader D artfish SRM Re ade r is an add-on product to the TeamPro and ProSuite Dartfish editions. It is used to link/unlink video files to data files generated by the SRM training system. Once linked, you'll be able to synchronize the data stre am s and video in the Analyzer and to view both simultaneously using the Data Graph . Drawing tools can be used to display data on the video image itself. The SRM Reader reads a data sou rce from the *.srm files generated by the SRM training system. You can link and synchronize several data sources to one video. For example, you could film two cyclists in the same video and synchronize the data recorded with two SRM systems (mounted on both bicycles). Useful links: www.srm.de - for more information on SRM. [email protected] - for questions related to the Dartfish SRM Reader. © Dartfish. All rights reserved. - Version 6 - Dartfish Readers 229 10.2.1 Requirements and installation To use the SRM Reader, you will need: Dartfish TeamPro or ProSuite version 4.5 or higher. Microsoft .NET framework 2.0 (automatically installed during the installation). Installation from CD To install Dartfis h SRM Reader, proceed as follows: 1. Insert the Dartfis h Data Reader installation CD into your CD or DVD drive. 2. Wait for the installation window to launch. If the installation window does not launch automatically, open Windows Explorer and locate the drive. Once you have selected the CD, double-click on the setup.exe file. For example, if your CD/DVD drive is classified under the letter E: you will double-click on E:\setup.exe. 3. Follow the instructions on the screen. When prompted, you must accept the licence agreement before the installation can proceed. Activating a Data Reader After installation each Data Reader must be activated. It is possible to use a Data Reader for a trial period then activate it at a later date. To activate a Data Reader, proceed as follows: 1. Right click a video file in the Tray or in the Item s L is t and select Link External Data from the context menu. All readers awaiting activation are listed. 3. Select the reader to be activated. 4. Click the Activate button. 5. Follow the instructions on screen. The reader can be activated immediately and automatically using an internet connection. When this is not practical you can manually apply for an activation code: The process will generate a page of information that you can email or fax to Dartfish. You will be sent an activation code that you must manually enter. The activate process requires that you provide your licence code. This will have been provided with your software purchase and is different from the code for your Dartfish Software or any other readers you have purchased. Updating Data Readers Data Readers are not automatically updated by the same process as Dartfish software. If and when updates become available, those who have purchased a Reader will be notified by email. Alternatively, updates can be dowloaded from the Dartfish website. Video tutorials will give you usefull guidance on how to use your SRM Reader. They can be accessed from the Start>Program s >Dartfis h >SRM Reader menu. - Version 6 - © Dartfish. All rights reserved. 230 Dartfish User Guide 10.2.2 SRM data Dartfis h SRM Reader retrieves the data from SRM files. The SRM training system includes a Powermeter and a Powercontrol to record biodata held in SRM files (*.srm). Thanks to this system, cyclists can record the power, the heart rate, the cadence, the speed and other data deriving from them. The source This Reader names the source by the initials of the person set in the Powermeter and the date of the training. The streams Five streams are fed: the Pow er developed on the crank in [watts] the Caden ce of the crank [rpm] the Speed of the cycle [km/h] the H eart rate of the athlete [bpm] the Tim e of the day at which the training session happened [hh:mm:ss.xxxx] 10.2.3 Linking Data The SRM reader establishes a link between a video file in your Dartfish L ibrary and an SRM file. This D ata Sou rce file is created by SRM software. A Data Sou rce typically contains multiple Data Stream s as illustrated in the following figure. The data streams are listed under the headings of their data sources: Caden ce, H eart rate, Pow er, Speed and Tim e are Data Stream s delivered by an SRM training system. © Dartfish. All rights reserved. - Version 6 - Dartfish Readers 231 The link cannot be established if one of these components is missing, i.e. Dartfish SRM Reader has to be installed. You already have imported your video clips into your Dartfish Library You have exported a data file from your SRM device to your hard drive (refer to the manufact urer's documentation to learn how to do this). 10.2.3.1 Linking Data You can create links between one video clip and more than one data s ou rce. To establish a link, right-click a video file in the Tray or in the Item s L is t and select Link External Data from the context menu. A Wizard first prompts you select the SRM Reader from a list of installed readers. - Version 6 - © Dartfish. All rights reserved. 232 Dartfish User Guide In the second step you will browse for the data file. © Dartfish. All rights reserved. - Version 6 - Dartfish Readers 233 A standard Open File... window pops up. Search for the data file in your hard drive and click Open. Before completing the Wizard you have the option to link other files to act as Data Sources for this video. 10.2.3.2 Managing links To manage links between video files and data sources, right click the video file in the L ibrary . Select M an age E xtern al Data... from the context menu. Removing the link You can remove the link between the data source(s) and the video file. To do this, data source and click on the U n lin k button. It is not possible to remove a single stream of a data source. Broken links A link can be broken when the external data source file has changed location on the disk or has been renamed. It also happens when the video clip is shared and opened on a different machine. As a result, the data cannot be displayed in the Analyzer any longer. To check for broken links right click the video file. Select M an age E xtern al Data from the context menu. Select the data source and its properties are visible on the right hand panel. If the link is broken the Availability property will read Sou rce M is s in g as shown below. - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 234 To correct a broken link, click the Relin k button then browse for the new location of the data source. Synchronisation of data and video is retained provided that the Dartclip metadata file has also been moved to the new location of the video file (see Sharing data for further information about Dartclip files). 10.2.4 Viewing data Dartfish's An alyzer M odu le is capable of displaying Data Stream data in 2 ways: 1. Text drawings, graph drawings and other specialist data drawings can be linked to data streams such that values can be displayed on the video image. The power, the cadence, the speed and the heart rate can be displayed with the Text and the Graph drawing tools, while the time can only be displayed with the Text drawing tool. Below is an example of what it might look like. Notice the symbols left to the data: These symbols are letters of the Dartfis h Sym bol font (see Drawings for more information). © Dartfish. All rights reserved. - Version 6 - Dartfish Readers 2. 235 Using the Data Graph panel each stream is represented as a different curve. The curves can be synchronized with the video. Since the data graph can display integers and floating points but not text, only the power, the cadence, the speed and the heart rate are displayed. 10.2.4.1 Synchronization You can quickly synchronize the data streams and the video in the Data Graph pane of the An alyzer, as illustrated below: To synchronize, proceed as follows: 1. Move to an appropriate position in the video clip. 2. Activate the synchronization mode by clicking on the Res yn ch button 3. Align the streams to the playhead (green arrow in the illustration) by click & drag of the streams to the left or to right. 4. Click a second time on the Res yn ch button once done. To synchronize precisely, you should position the video to a distinct instant where you might expect to see an obvious change in the data graph e.g. when the athlete starts pedaling. This can be easily matched, for example, to the cadence stream (see illustration above). - Version 6 - © Dartfish. All rights reserved. Dartfish User Guide 236 10.2.4.2 Drawings The data can be directly overlayed on the video image in the An alyzer. This is done by linking drawings to data from a Data Stream . The following is a representative but not comprehensive list of drawing tools that can be linked to data. Different devices will produce data which can be best represented by different types of drawing: Text tool: Use to display any value from a Data Stream. Using the Dartfish symbol font, the text tool can also be used to display data specific icons to label values (see below). Graph tool: Use to represent numerical data as a graph. Force Meter: Use to represent the magnitude and direction of a force (typically for devices producing this type of data). To link a drawing to a data stream (example using Te xt drawing): 1. Use the Text drawing tool to create a small text drawing. The text is not important e.g. "xxx". Be sure to finish editing the text before proceeding to the next step; to do this click on the video display outside the drawing. 2. Right click on the drawing to display the context menu. 3. Select the E xtern al Data Dis play... option. 4. Select the Data Sou rce and Data Stream then click the OK button. © Dartfish. All rights reserved. - Version 6 - Dartfish Readers 5. 237 The text box now displays the value of the selected data stream. Don't forget to synchronise to make sure the displayed values have proper meaning. Displaying Dartfish explanatory symbols The Dartfis h SRM Reader provides the Dartfis h Sym bol font which you can use with the Text tool of the An alyzer or In th e Action modules. Using this you can substitute long names with self-descriptive symbols. See the Table 1 for the key mapping. Key Symbol (character) Description S or s Speed P or p Power C or c Cadence (pedals) H or h Heart rate The Dartfis h Sym bol font is automatically installed with the Dartfis h SRM Reader. 10.2.5 Sharing linked data In order for others to see linked data you have two options: 1. You can publish a movie from the Analyzer. This will include drawings that have been added to the video clip - including those displaying Data Streams. 2. You can share the video file and the Data Source with other Dartfish users. Although the recipient will need to re-establish the link using their own SRM Reader, synchronization is retained. - Version 6 - © Dartfish. All rights reserved. 238 Dartfish User Guide 10.2.5.1 Publishing You can publish the video with overlayed data from the An alyzer (see Saving movies from the Analyzer to learn how to do this) as illustrated below: In this case, the result is a video that can be shared in your team. It does not require Dartfish to play it. You cannot embed the data in the video file (i.e. in the .dartclip file associated to the video clip). The Dartfis h SRM Reader only creates a "live" link between both the data and video files. 10.2.5.2 Sharing data The Dartfis h SRM Reader does not embed data in the video file (i.e. in the .dartclip file associated with the video clip). It only creates a "live" link between the data and video files. Therefore if you wish to share video and linked data with other Dartfish users the following are required: The recipient must have Dartfish Software The recipient must have the Dartfish SRM Reader add-on. You must provide the video clip, the Data Source file and the Dartclip file as shown below. © Dartfish. All rights reserved. - Version 6 - Dartfish Readers 239 The recipient establishes a link using the Relin k function described in Managing links. Dartclip files store all additions made to video by Dartfish. These include details of external data links and synchronisation. If the Dartclip file has not been shared then the recipient must create a new link between the video clip and Data Sou rce. - Version 6 - © Dartfish. All rights reserved.
