Avid DS Nitris v7.5 Release Notes • 5
The following sections outline the new features in this release.
You can use the Ctrl+Z keyboard shortcut to perform an undo while editing text in the 3D DVE layout.
Image Blur Output Filter
On the Output property page of the Option property editor, a new option, called Enable Image Blur, lets you apply a slight blur (a 3x3 convolution) to the 3D DVE. This helps to remove the jaggies.
Audio Media Conversion
You can convert audio clips based on the sequence video frame rate. For example, say you want to convert a sequence from true 24 fps to 23.976 fps
(NTSC). Any synced clips will be converted so that their sample rate remains the same, however they are now timed with the new video frame rate of
23.976. For more information, see “Converting the Video Frame Rate of
Synced Clips” on page 897 .
With this feature, conforming of sequences from other applications is much simpler, as you no longer have to be concerned about mismatched frame rates.
Timecode Support for BWF Files
Avid DS has the ability to read and store the timecode in a Broadcast Wave
Format (BWF) file.
New HD Compressions
is a new 10- and 8-bit HD encoding technology that delivers mastering-quality HD media with storage bandwidth and capacity requirements rivaling those of uncompressed standard-definition (SD) files.
Specifically engineered for multi-generation editing, the quality and efficiency of Avid DNxHD-encoded HD media enables real-time collaborative HD production in networked environments.
6 • Avid DS Nitris v7.5 Release Notes
Unlike uncompressed HD media, which has bandwidth requirements of nearly 1.2 gigabits per second (Gbps), Avid DNxHD operates in a 4:2:2 color space at much lower, more efficient data rates. You can select from the following compressions when capturing HD media:
• For 1080i/60, 1080i/59.94, 1080PsF/30, 1080PsF/29.97, 720p/60,
DNxHD 220 10-bit (data rate approximately 220 Mbits/sec)
DNxHD 220 8-bit (data rate approximately 220 Mbits/sec)
DNxHD 145 8-bit (data rate approximately 145 Mbits/sec)
• For 1080i/50, 1080PsF/25:
DNxHD 18510-bit (data rate approximately 185 Mbits/sec)
DNxHD 185 8-bit (data rate approximately 185 Mbits/sec)
DNxHD 120 8-bit (data rate approximately 120 Mbits/sec
• For 1080PsF/24, 1080PsF/23.97:
DNxHD 17510-bit (data rate approximately 175 Mbits/sec)
DNxHD 175 8-bit (data rate approximately 175 Mbits/sec)
DNxHD 115 8-bit (data rate approximately 115 Mbits/sec)
Like uncompressed HD, these formats let you play multiple streams of full-resolution effects, such as color correction, DVEs, transitions, and titles, in real time. Avid DNxHD encoding creates either .gen files or Material
Exchange Format (MXF) files. For more information, see
Shared Media Formats
Avid DS Nitris now lets you link to and play in real time MXF and OMFI media in the following formats:
• DV 25
• DV 50
• MPEG2 IMX 30 Mbps, 40 Mbps, 50 Mbps
• Uncompressed (1:1)
• JFIF (interlaced) 2:1, 3:1, 10:1, and 20:1
• JFIF (single-field) 2:1s, 4:1s, and 15:1s
You can share this media with other Avid editing systems using AFE files and
Avid Unity MediaNetwork shared storage.
Avid DS Nitris v7.5 Release Notes • 7
For MXF 1:1, 2:1, 3:1, 10:1, and 20:1, Avid DS Nitris also supports capture from tape.
The Capture Tool includes these new features:
• Add locators: You can add locators (markers) to the clips you are capturing from tape or on-the-fly. These markers are linked to a specific timecode and behave in the same way as Clip locators. Use keys F1 through F3 (or the corresponding buttons) to add locators with predefined messages:
F1: Needs color correction
F2: Needs scratch removal
F3: Start of good take
You can also use the following keys or buttons:
A key (Add button): Add a locator with an incrementally numbered title (Locator x) and a custom message.
S key (Scene button): Add a locator with the title “Scene x, Take x”
Each time you click the Scene button, the Scene number is incremented and the Take number is reset to 1. You can add a custom message.
T key (Take button): Add a locator with the title “Scene x, Take x.”
Each time you click the Take button, the Take number is incremented.
You cannot add locators during Live capture.
For more information, see “Adding Locators While Capturing” in the
Avid DS Nitris Capture and Output Guide.
• Select timecode source: For Live capture, you can select one of the following timecode sources:
VITC or LTC through the RS-422 serial connection on the computer
LTC through the LTC IN connection (XLR) on the Avid Nitris DNA
• Stop capture:You can stop the capture process by pressing the ESC key or clicking the Start/Stop Capture button. You have the option of keeping the material already captured.
In and Out buttons: For capture on-the-fly, you can click the In and Out buttons (or press the I and O keys) to set In and Out points. You can still set In and Out points by clicking the left mouse button and the right mouse button.
8 • Avid DS Nitris v7.5 Release Notes
• Custom preroll: You can set a custom preroll for a deck in both the
Capture tool and the Output tool. This setting temporarily overrides the setting in the Deck template but does not change it.
• Message/Progress bar: A field near the top of the Capture tool displays status messages and a progress bar when capturing Live, Tape, or
• Sync button: You can specify the Sync source (tri-level or black burst) in the Capture tool by clicking the Sync button. This button still appears in the Output tool.
You can capture from and output to an ADAT audio recorder, through the
Optical connectors on the Avid Nitris DNA. Select ADAT as audio input in the Deck Configuration view or in the Capture Tool.
SDI Embedded Audio Support
You can capture and output up to 8 channels of embedded SDI audio. Select
Embedded as Input and SD Embedded as Priority in the Deck Configuration view or in the Capture Tool.
Increased Range for Component Video Input
The range of video input for SD Component (professional mode) has been increased. The R-Y and B-Y slider now extend from 0 to 431.
Capturing as Separate Mono Tracks
Select this option if you are sharing MXF media with other Avid editing applications. By default, Avid DS Nitris creates a single .wav or MXF file and track from a multi-stream audio file. This is the most efficient way to work with audio files in Avid DS Nitris. However, because other Avid applications cannot link to a multi-stream file, you need to select this option so that Avid DS Nitris creates multiple single-stream files.
This option appears in the following dialog boxes: Capture Settings, New
Sequence, New Project, and Sequence Preferences (Audio property page).
Recapture with Options Dialog Box
The Explorer Recapture Options dialog box now automatically selects all audio tracks that you have enabled in the Deck Configuration tool. This change makes it easier to recapture clips that include audio tracks.
Avid DS Nitris v7.5 Release Notes • 9
Pixel Ratio for Graphics Capture
The Capture Settings dialog box includes new options for setting the pixel ratio for captured graphics.
• The Pixel Ratio section includes an Auto check box. Select this option if you want Avid DS Nitris to use the pixel ratio specified in the source graphics file. If the application can’t determine the pixel ratio, it uses the
Standard or Custom setting.
• The Standard menu includes a new option: Current Sequence. Select this option to use the pixel ratio that is associated with the sequence. This option is especially useful for custom sequences that use a non-standard aspect ratio.
• In the Capture Settings dialog box, Custom pixel ratios can be specified to four decimal places.
These options, and others relating to the format of the source files, are now grouped in the Source Description section.
Improved Performance when Reading 2K DPX Files Natively
A new software codec permits the direct reading of DPX files in their native format. The codec will also linearize the material based on the LUT as specified in the DPX import tool.
The Output Tool now includes:
Preview output: Click the Preview button to view your sequence before outputting to tape.
• Output LTC: You can specify LTC output and, for NTSC projects, select either drop-frame or non-drop-frame. You can also use LTC output for downconverting. LTC is output as sequence time.
• Custom preroll: As in the Capture tool, this setting temporarily overrides the setting in the Deck template but does not change it
Edit mode: You can choose to output to tape in either Auto (Insert) or
Assemble by selecting from the Edit Mode menu in the Output Tool.
This setting also temporarily overrides the setting in the Deck template but does not change it.
10 • Avid DS Nitris v7.5 Release Notes
HD H Phase (Output Timing) slider
You can adjust the HD H Phase (output timing) for output from tape to HD equipment. A slider is displayed in the Video Output panel of the Output tool when you select “HD Analog Out and HD H Phase.” This setting applies to any HD equipment (not only HD Analog equipment). Default values depend on the sync source you select.
Deck Configuration View
The Deck Configuration View now includes:
• Notes for deck templates:A read-only text box at the bottom of the
Deck Configuration Tool displays notes about the selected deck template. Not all templates include notes.
Preset for microphone input: The Deck Configuration tool includes a preset labeled Microphone Input. If you connect a microphone to the
Avid Nitris DNA, you can record through the microphone by selecting this preset in the Capture Tool. For more information, see “Capturing
Audio through a Microphone” in the Avid DS Nitris Capture and Output

• Broadcast Wave Format (BWF) files : You can now read, and store timecode from audio Broadcast Wave Format files.
• When importing a DPX file, you can include the 24-fps SMPTE timecode from the original scanned film in the DPX header . When exporting DPX files, you can also include a timecode, which is inserted in the DPX header. .
• For MXF and .gen export, you can choose the following compressions:
JFIF 2:1, 3:1, 10:1, 20:1
MPEG2 IMX 30 Mbps, 40 Mps, or 50 Mbps
Layered Photoshop Import
When importing layered Photoshop graphics, Avid DS Nitris lets you set the pixel ratio in the Capture Settings dialog box. In previous versions,
Avid DS Nitris imported the graphic using the pixel ratio of the current sequence.
Compositing and Effects
New and Improved Composite Effect Node Property Editor
The Composite effect node property editor has been improved to include the following:
• A visual property editor
• Dynamic input
• A central property page combining all properties previously spread out in multiple property pages

• Real time performance
For more information, see Compositing Multiple Images in the Help.
LogLin Remapping Effect
This new effect lets you linearize DPX and Cineon images while keeping the
DPX inputs in the original log space when linking or importing. You can apply the linearization only when needed before applying certain effects.
You can also apply this effect after another effect to visualize the linearized output of those effects, while the inputs to those effects remain in log space.
After you've completed the interactive session, you can bypass the Lin2Log effect to allow the output images to be written in the native log space.
The LogLin Remapping effect is real-time playable and uses the existing
Nitris hardware if available.
It consists of the log2lin and lin2log presets that are available in the /Image
Effects folder. You can apply these presets on a clip, track, timeline, or in the
Log2Lin: The log2lin effect lets you linearize film-based media through a log2lin remapping. For more information, see Log2Lin in the Help
• Lin2Log: The lin2log effect lets you convert linearized media back to the original log-based format. For more information, see Lin2Log in the
Also, see Linearizing Film-Based Material in the Help.
Color Correction Effect Improvements
A number of improvements have been made to the Color Correction effect property editor to allow you to work more efficiently:
• A large Color Correction effect property editor is now loaded when you double-click the Color Correction effect in the Layers view and in the
Effects Tree. To switch to the Effects Layout, click the Effects Layout button in the taskbar.
• All controls related to Luma and Chroma have been classified respectively.
Avid DS Nitris v7.5 Release Notes • 13
• In addition to the Gamma control of the Luma in the image, you can also adjust the Gamma of the RGB values in the image by using the RGB
• You can adjust the Gamma, Gain, and Setup controls for each Red,
Green, and Blue channels. You can also adjust the same controls for the master RGB of the image.
• You can now set legal RGB clipping values.
• You can use the color correction effect to linearize film-based media by using the controls in the Levels property page. A Softclip control is also available when converting log-based data to lin-based data.
For more information, see Color Correcting Images in the Help.
The following presets are now available:
Spill Subtract preset can be applied on the timeline or in the Effects
Tree. It allows you to subtract out the contribution of the background color from the spill areas to recover the original foreground color once an initial key matte has been extracted.
• Un-premultiply from Color preset can be applied on the timeline and in the Effects Tree. It is useful for recovering the original foreground image colors (especially in the semi-transparent and motion blur regions). It is also useful when the images and corresponding mattes are generated from applications such as Adobe Photoshop or Adobe After Effects and have options such as Premultiply with Color.
• Un-composite from Bgnd preset can only be applied in the FX tree and is similar to the Un-premultiply from Color, except it uses the original background image instead of a user selected background color.
• Key Combiner - Alpha and Key Combiner - Luma—see
For more information, see Keying in the Help.
Working with Photoshop Files Improvements
• A majority of Photoshop blending modes are now supported and mapped correctly in Avid DS Nitris when you capture a .psd file. Therefore, a vast majority of blending and layer operations performed in Photoshop are now maintained in the new DS sequence.
14 • Avid DS Nitris v7.5 Release Notes
• Translation from Photoshop to Avid DS Nitris has also improved because the Mix setting, the transparency method used in Photoshop is now available. When you capture a .psd file, the transparency is automatically set to Mix.
• Clamp To Valid RGBA Value option is now available in Avid DS Nitris allowing a better translation from Photoshop.
For more information, see Working with Layered Photoshop Images in the
Blending Operation Effect Nodes
Various two-input presets have been created for the multiple blending modes available for compositing purposes. They can be added as effect nodes in the
Effects Tree—see Applying Blending Operations in the Effects Tree in the
Organizing Nodes in the Effects Tree
New commands have been added to the Effects Tree menu to allow you to work more efficiently with large and complex Effects Trees. You can now organize all nodes or a subtree of the Effects Tree—see Organizing Nodes and the Effects Tree Menu in the Help.
Converting Stack of Effects to an Effects Tree
You can now convert a stack of effects on a clip, track, or timeline to an
Effects Tree. This feature saves screen real estate helping you work more efficiently and allows you to bundle and save Effects Tree presets easily—see
Converting a Stack of Effects to an Effects Tree in the Help.
Using Opacity as Mix
In the Layers view and Composite effect node, you can now mix or blend the result of the blending operation for a particular layer with its background layer. Opacity is selected by default—see Adjusting the Opacity of a Layer in the Help.
Clamp to Valid RGBA Values
In the Layers view and the Composite effect node, clamping is now available so that all inputs and out of the compositing operations are guaranteed to be within the valid RGBA range regardless of the image format and processing precision being used. This option is OFF by default.
Avid DS Nitris v7.5 Release Notes • 15
However, when importing .psd files this option is ON by default. The RGBA values are automatically clipped for each layer before or after any blending operation.
Avid DS Nitris Editor users will now be able to apply a matte to a video track to combine an RGB image with a matte from another image. This effect is real-time playable and uses the existing Nitris hardware if available.
During AFE conforms, Matte Key effects from other Avid editing systems now conform to Matte containers whenever possible—see Conforming Matte
Keys and Alpha Channels in the Help.
For more information, see Using Matte Containers on the Timeline in the
Key Combiner Effect
There are now two seperate Key Combiner presets—Key Combiner - Alpha and Key Combiner - Luma. The effect is real-time playable and uses the exisiting Nitris hardware when using the alpha channel of the Alpha input.
You can also now set the premultipled state of the output.
Compositing Operations in Shapes Property Page
New compositing operations have been added to the Shapes page of all keyer and matte effects.You can now choose how shapes are composited by selecting any of the compositing methods.
Antialiasing and Blur Properties
New antialiasing and blur properties on the Shapes property page let you control the quality of antialiased shapes. The Shapes property page appears in the following effects: Matte, Blue-Green Keyer, Chroma Keyer, and Linear
The new antialiasing properties include:
• Apply lets you specify if shapes are antialiased or not.
• Extra Filtering provides subpixel control of extra filtering applied to the antialiasing. This property allows a tradeoff between image sharpness and smoothness of the antialiasing.
• Supersampling lets you select the precision of the antialiasing; a value of 8x8 provides higher precision than 4x4.
16 • Avid DS Nitris v7.5 Release Notes
These properties are also availabe in the Tracker/Stablizer property editor.
The new blur properties let you blur shapes in the X and Y directions. The shape blur algorithm has been changed to be faster and more memory efficient.
Note: If you are using sequences that contain blurred shapes created in previous releases of Avid DS Nitris, you might need to fine-tune the blur properties in the Shapes property editor.
The Mix Parameter Improvement
You can now toggle to turn on and off the use of the Mix parameter without affecting the mix curves in the animation graph.
Replacing Layer Effects
You can now replace the Key effect in the Layers view with any one-input effect preset from the Keyer property editor.
Material Exchange Format (MXF)
This version of Avid DS Nitris supports MXF as a native format. MXF
(Material Exchange Format) is an industry-standard container format that encapsulates media and production metadata into a single file.
MXF is supported as a common file format on other Avid applications, enabling direct media interchange between these applications and third-party
The following Avid applications can create, play, output, and share MXF files:
• Avid DS Nitris v7.5 and later
• Media Composer Adrenaline v1.5 and later
• Avid Xpress Pro v4.5 and later
• Avid Xpress DV v4.5 and later
• NewsCutter Adrenaline FX v5.5 and later

For a list of supported resolutions, and other information about working with
MXF files, see
and “Sharing MXF
Media” in the Help.
Avid DS Nitris v7.5 Release Notes • 17
To support MXF files on Avid DS Nitris, you need to configure at least two storage devices: one for MXF video and one for MXF audio—see
“Configuring Storage for your Workstation” in the Help.
Note that only source clips (material captured from tape or from file) are created as MXF files. Processed or converted clips (caches) are created as
.gen or .wav files.
MXF is also available as a file format for import and export.
Create AAF Files
This release of Avid DS Nitris lets you create an AAF file from a master clip.
The AAF (Advanced Authoring Format) file contains composition information in a format that can be shared with other applications, such as
Avid Media Composer. These files contain the metadata for the master clip but not the media itself.
To create an AAF file, right-click one or more master clips in a bin and select
Export to AAF. Navigate to the folder where you want to save the file and click Select. AAF files are created with the same names as the clips.
Mattes Conformed as Matte Containers
Traditional matte keys (Matte Key effect) and imported matte keys (still graphics and QuickTime movies ) are now conformed as Matte containers—see
. For QuickTime movies, you need to manually invert the alpha channel. Imported matte keys that are promoted to 3D continue to be conformed as a DVE within a Composite container.
• Because the toolbars now keep track of presets that were added and removed, presets in the User Presets folder located under C:\Program
Files\Avid\DS_v7.5\Preferences\User Folder\Toolbars\Presets are automatically deleted.
• Presets, including a multi-selection of presets, can be dragged and dropped on a menu button (multiple menu commands are created) or to an empty area of a toolbar (multiple buttons are automatically created).
• When a toolbar is set to auto-close, they now close themselves when you drag a preset button and drop it on the timeline or Effects Tree.

Nitris Editing Guide.
Mix and Match Frame Rates
You can drop a clip on the timeline even if it has a different frame rate than that of the current sequence. When you place it on the timeline, a red highlight will appear in the timeline ribbon indicating that the clip must be processed. When you process the clip, new media is created at the frame rate of the current sequence.
For more information, see “Placing Clips of Different Frame Rates on the
Timeline” on page 560 .
Timeline Performance Improvements
There are significant interactive performance improvements for long form and effects intensive sequences.
Timecode Matching in the Timeline
If you need to drop several source shots with matching timecodes on the timeline in sync by their source timecodes, hold down the U key while you drag and drop a clip. Each clip will be synced by source code to the highest live track.

Video Levels Test Patterns
The video levels test patterns have changed; some have been removed and some test pattern generators created with previous versions of Avid DS Nitris might display black now. The old test pattern folder is still available on the
Animation keys displayed in the position bar beneath the Source and Record viewers let you view the position of keys and move them to a new timecode without having to use the animation editor.
To view the animation keys of an effect, simply select an effect on the timeline. Red lines in the position indicator represent the animation keys (if any).
To snap the position indicator to the animation key and move them together simultaneously, press Ctrl and select the animation key.
Filtering the animation tree lets you choose which parameters to display in the tree. You can save multiple filters and switch between the filters. Filtering is available through the Edit Filter dialog box; select View > Edit Filter—see
“Filtering Function Curves” in the Help.
HD Hardware Compression
With the new Avid DNxHD (Digital Nonlinear Extensible, High Definition) hardware codecs, you can edit HD in real time uncompressed, or in the new
DNxHD compressed mode. Avid DS Nitris will deliver real time effects in both cases. See
New Graphics Card
A new graphics card—ATI FireGL X2 (256 MB), is shipping with the
Avid DS Nitris DNA workstation.
The Avid Nitris DNA now allows microphone input through two XLR connectors (MIC 1 and MIC 2). Use one input for mono or both inputs for stereo. In the Capture tool, select Microphone Input from the Deck list. (See
Avid DS Nitris v7.5 Release Notes • 23
LTC Input and Output
The Avid Nitris DNA now allows input and output through the LTC IN and
LTC OUT XLR connectors on the Avid Nitris DNA are now active (See
ADAT Input and Output
You can capture from and output to an ADAT audio recorder through the
Optical connectors on the Avid Nitris DNA. Select ADAT as audio input in the Deck Configuration view or in the Capture Tool.
All media is backward compatible between v7.0x and 7.5, so no archive of media is necessary. However, once a sequence and/or media is created in v7.5, it cannot be played in 7.0x.
Any effects that were previously processed in v7.0x will need to be reprocessed to regenerate the caches.
Drag and Drop in Media Tool
To display associations for an item displayed in Media Tool, simply drag an item to an empty part of the same panel (you no longer have to right-click).
Tapeless Archive for Post-Production
The Tapeless Archive feature uses archiving technology to make the telecine transfer process more cost-efficient for film-originated television shows.
Current methods either use negative cutting or tape-to-tape transfer to create the final tape or tapes. A workflow that uses Tapeless Archive uses a telecine transfer to create the final tape.
To enable this feature, open the Command Mapping window, and add the
Tapeless Archive command from the Editing Group to a toolbar button.
To use the tapeless archive process, follow this basic workflow:
1. Transfer the film rushes onto beta SP tapes synced with audio as a low-cost, one-light transfer. Each rushes roll corresponds to a punched negative roll.
2. On an offline system, edit the sequence, then output a digital cut for reference and an AFE file.
24 • Avid DS Nitris v7.5 Release Notes
3. On the Avid DS Nitris system, import the AFE file. Batch capture the video and audio with the desired handles. Capture the digital cut for reference.
4. Edit the sequence (do not finish all effects).
5. Create the tapeless archive. The archive list allows for handles, duplicated use of shots, and combines neighboring shots into single events, resulting an a list that minimizes the required footage.
6. Send the archive tape log to a telecine suite.
7. The telecine operator uses the tape log to create a best-light transfer to a single tape.
8. Restore the archived project, using the tape provided by the telecine operator.
9. Complete the effects and titling to finish the show. Drag the handles to get more material if necessary.
10. Create the final master tape.
If, during finishing, you need to get retransfer a clip (perhaps to get longer handles), you can determine the original film and tape roll numbers and timecode from the clip properties. Then have a telecine transfer done on this clip, and recapture the clip.
Display Navigation Dialog Box for Relink
When you need to relink a clip and want to display a navigation dialog box, hold down the Control key while you select the Relink command or click the
Improved Graphics Processing
Processing of frame-based real-time graphics is improved when:
• Inside or outside the paint context,
• A frame is outside a graphics session, such as when visiting a painted frame while in a different layout, and
• A frame is inside the paint context, but not requesting the current frame, such as when using the Onion Skin feature in a graphics session.
Avid DS Nitris v7.5 Release Notes • 25
Blending Modes in Color Blend Property Editor
You can now use different blending modes in the Color Blend paint effect.
These modes let you control how graphics objects blend with the background image. These are the same blending operations that can be performed between layers in the Compositing layout.
The blending modes are available from the Blending property page of the
Color Blend effect—see “Blending Graphics Objects or Titles” and “Color
Blend” in the Help.
Type Property Page Renamed
The Type property page in the Color Blend paint effect has been renamed
Rectangle with Rounded Corners
When using the Rectangle tool, you can create rectangles with rounded corners. You can specify the corner roundness using the Corner Radius parameter on the Rectangle property editor or interactively, using the close bracket (]) or open bracket ([) keys to change the corner radius while creating the rectangle—see “Drawing Rectangles and Ellipses” in the Help.
Fill Rule Property
The Fill Rule property lets you determine which areas of a shape are filled or become holes, letting you adjust the appearance of a compound path or a self-intersecting path. You can make a path either non-zero winding or even-odd, depending on how you want them to look. The Fill Rule property is available from the Paint Style and Brush (custom brushes only) property editors—see “Filling Shapes” in the Help.
Reversing Path Direction
You can now reverse the path direction of a stroke. A stroke has a start point and an end point. By reversing the direction of a stroke, the start point becomes the end point and vice versa.
Reversing the direction of a path is useful when working with Handwriting animation or when using the Non-Zero Winding fill rule on a compound stroke.
This option is available from the Edit Shape property editor—see “Changing the Direction of a Stroke” in the Help.
26 • Avid DS Nitris v7.5 Release Notes
New antialiasing properties let you control the quality of antialiased filled strokes and antialiased characters. These properties are available on both the
Paint Style and Font property pages:
• Use lets you specify if characters/strokes are antialiased or not. Smooths the jagged lines that occur with diagonal or curved strokes. For text, characters must be antialiased most of the time, but you might want to turn off antialiasing on very small characters.
• Extra Filtering provides subpixel control of extra filtering applied to the antialiasing. This property allows a tradeoff between image sharpness and smoothness of the antialiasing.
• Supersampling lets you select the precision of the antialiasing; a value of 8x8 provides higher precision than 4x4.
All Font Styles Available for a Font Family
All font styles are now available for a font family. When you select a font name from the Titling Font property editor, all styles available for that font will be displayed, such as Condensed, Roman, Thin, Ultra-Thin, Demi-Bold,
Ultra-Black, Heavy, Oblique, Upright, Inclined, Engraved, and so on.
While editing text, you can:
• Move the text box interactively by holding the Alt key and dragging the box to a new location.
• Edit another text body by pressing Alt and clicking a different text body.
• Edit the next text body by pressing Alt+. (period).
• Edit the previous text body by pressing Alt+, (comma).
• You can now import international characters, such as Chinese and
• All DS Subtitles files must be saved as Unicode encoded text files. ANSI encoded text files are no longer supported.
• The full path of a titling body preset no longer needs to be specified in the header section. Just be sure to place the preset in the factory default folder for titling presets: \Program
Avid DS Nitris v7.5 Release Notes • 27
Applying Blur to Titles
You can blur titles horizontally and/or vertically. On the Titling Style property editor, the Softness property for the face, edge, and shadow has been replaced by the Blur X and Blur Y properties.
When using sequences that contain text created in previous releases of
Avid DS Nitris, you might need to finetune the text if it had the Softness property applied to it in the Titling Style property editor.
Missing Fonts Logged in Avid Event Log
When restoring a project and opening sequences of that project, missing
Graphics titling fonts are logged in the Avid Event Log. By checking the log, you’ll see exactly which fonts are missing on your system. To access the Avid
Event Log, select View > Multi-Instance Views > Avid Event Log.
True RGB 4:4:4 Processing with Real-time Proxy
When working with RGB 4:4:4 in film mode, you can easily view the processed results as an HD proxy without having to reprocess of all of the content.
The time to generate a real-time playable cache in an RGB 4:4:4 sequence has also been significantly reduced. Each time Avid DS detects existing RGB caches at any level, it takes the highest quality cache, and converts it to the requested proxy format.
The algorithm for processing real-time effects has been enhanced to reduce the processing time. All non-Real-time effects are quickly processed in
“minimal” mode so that a cache is generated to allow real-time playback of your sequence.
The same happens when you choose to include Potentially Real-Time
Effects or Guaranteed Real-Time Effects in the Processing Options dialog box. It forces processing of any real-time effects (yellow or green highlighted areas) on your timeline.
28 • Avid DS Nitris v7.5 Release Notes
Internal Cache Generation at Effect Input Level
Combined with the Smart Processing feature, the new internal cache generation at each effect input level, now allows for better real-time playback of stacked effects (e.g. when you have a stack of real-time effects on top of non-Real-time effects).
With the cache generation at each level, you can place the floating viewer, or use the Reconnect Viewer feature on any single effect, and view the processed result in real-time.
Increased Processing Speed
• Increased speed when processing frame-based, real-time graphics effects.
• Overall processing speed has increased with the new hardware codecs for decompressing compressed images.
• faster inter-layer compositing operations in the Layers View and the
• faster Multi-tap quality in the DVE
Effects that are now Real-time
For a complete list of all the real-time effects in Avid DS Nitris,
• Composite node in the effects tree will now run in real-time.
• Matte Composite node in the effects tree will now run in
There is a new send-in-background option with RP. RP jobs are sent to the
DMS in the background, so that you can resume working on your sequence much sooner.
Overiding Processing Precision and Type
You can now override the Processing precision and Processing Type from the new cache nodes property editor.

The following sections cover additional notes and workarounds for possible limitations in this version. The Avid DS Customer Support website: www.softimage.com/avidds also has a comprehensive database of information.
If you encounter a problem on your system that is not covered here, please refer to the Avid DS Knowledge Base for workarounds on known issues.
Keyboard Shortcuts Unavailable
While in the 3D DVE layout and using the viewer, you cannot create a new sequence or quit the application using the keyboard shortcuts. To work around this, use the corresponding commands in the menu bar.
Locators not functional in Live capture using XLR timecode
If you select XLR as the timecode source for capture, and assign locators, the locators do not appear on the clip in the timeline.
Compositing and Effects
SuperBlack and SuperWhite Not Preserved
SuperBlack and SuperWhite information (full YCbCr range) is not preserved:
• When using Pixel/Channel Masking (Masking PPG) on effects when
8-bit precision is used. Effects are set to 8-bit precision when:
Setting the precision to Auto (Options PPG) with the Precision sequence preference set to 8-bit
Setting the Precision to 8-bit (Options PPG)
• When using some DS effects not supporting 16-bit or 32-bit/Float precision (such as Impressionist or Painterly effects).
• When using some third-party effects not supporting 16-bit or 32-bit/Float precision.
4-Point Tracker Not Showing Result in Layers View
When tracking from the Layers view, the 4-point tracker doesn't show result when set to Result in
30 • Avid DS Nitris v7.5 Release Notes
Workaround: Select the Output Frame Size option in the Options property page before you perform 4-point tracking in the Layers view.
Streaming capture has been deactivated for Beta. The result is that capture from the timeline will capture each track of a clip one at a time. Also, when multiple clips are close to each other on a tape, Avid DS will not capture all of them at once. Instead, each one will be captured independently.
Still images captured as OMF (JFIF) compressed media in other Avid editing systems and exported through AAF or AFE files do not conform. The clip is displayed as "Media not available." These files cannot be archived.
Master clips with alpha created on other Avid editing systems do not conform. Each clip in the matte container has both alpha and fill.
MXF audio files exported from Avid DS Nitris do not play in other Avid editing systems.
When capturing media, clicking the Capture button twice causes DS to crash.
The Media Indexer might not work because of a problem communicating with QuickTime. Avid DS Nitris displays an Sicore error message whenever the Media Indexer tries to run. Workaround: Try upgrading to QuickTime
When restoring an archive that contains MXF video clips, the timecode of the restored clips does not match the original timecode.
Audio files (.aiff and .wav) captured from tape in other Avid editing systems and exported through AAF or AFE files do not relink. Audio captured from files do not have this problem. Workaround: Export an .omf file with audio embedded and conform it after you conform the AAF or AFE file.
Video clip with a semicolon in the name does not conform
If you conform an AFE file that includes an MXF or OMF video clip with a semicolon (;) in the file name, the video media does not relink to the clip.
Audio media plays, but video displays a “Media not found” message.
Simply remove the semicolon from the file name.
We recommend that you DO NOT change your Windows desktop theme, as this results in some known issues with Avid DS.
Avid DS Nitris v7.5 Release Notes • 31
If you really need to change your Windows desktop theme, make sure you restart your system before using Avid DS.
Changing Sequence Preferences
If you experience problems when you change settings in the Sequence
Preferences dialog box, please restart Avid DS.
It is currently not possible to archive any 10-bit alpha media contained when an 8-bit sequence is open.
Archiving of DNxHD media with alpha channels does not work correctly.
This problem will be fixed in the Beta 2 release.
