Control Panel
The goal of this tutorial is to introduce the IPDirector Control Panel and describe its main operations.
The Control panel is a graphical user interface for previewing and manipulating clips, record trains and playlists
stored on EVS servers or files saved on a nearline storage connected to the GigE network.
It can also be used to control the servers' playout channels to broadcast different elements. Several Control Panels
can be used simultaneously to control various playout channels.
An overview of IPDirector's Control Panel will be featured in this manual.
User Interface
To open the Control Panel, click on its button in the main toolbar.
As shown, we already have an operational Control Panel open to explain its interface.
The Control Panel and display buttons to access the different panes
The Control Panel contains several panes that allow us to perform various operations. To access different panes, we
need to click on the Pane display buttons.
In the Channel Media pane we can load a clip, a playlist or a record
train from an EVS server. At the same time it provides information
about loaded elements, such as the name and the LSM ID.

If an Audio Video board has been configured, the Video Display pane allows us to view elements loaded on the
Control Panel.
The Transport Functions pane displays a Jog bar and transport
functions, allowing us to navigate within the loaded element.


the first one is the Clip Information tab, displaying data about the clip such as keywords, interest level, etc;

the Metadata tab allows us to view and modify metadata. For instance, its profile and fields can be
changed;

the Ganged Channels tab allows the control of ganged
channels;

and finally the Clip List tab, where simple playlists can be
created and played out.

Clip Creation
To demonstrate the clip creation process, we will start over from the beginning.
First, we need to open a Control panel and assign it a server playout channel - or the Software player.
1. Assigning a Player Channel to the Control Panel
There are three ways to assign a playout channel to the Control panel:

The first way is to open the Channel Explorer as well as the server's Tree structure.
Then, right-click on a Player channel and select 'Open Control Panel' from the contextual menu.
Once the Control Panel is open, we will notice that the
server's Player channel we selected is now associated
with our Control Panel.
From here on, we can now control the Player channel.
Open Control Panel.

The second way is to open the Control Panel, then drag & drop a Player channel into it from the
Channel Explorer.
Let's open a new Control Panel from the Main toolbar.
Select another Player channel from the Channel Explorer, then drag & drop it in this Control Panel.
We can see that this channel has now been assigned to the Control Panel.


The third way is to open the Control Panel and right-click on the Channel field. From the contextual
menu displaying available playout channels, let's select the channel we want to use.
Selection from the contextual menu
If needed, we can select a Player channel from another server that is available on the network.
This channel has now been assigned to the panel and we can control it from here.
2. Loading Media and Creating Clips
To start creating clips, we need to load a Record train from a server in the Control Panel.
Let's close the two panels that we will not use and keep the one with Video display to demonstrate this
operation.
Here again, there are several methods in loading a Record train.
The one we will use is the following: In the Channel Explorer, select
the Record train, then drag and drop it into the Control Panel.
The Record train is now loaded on the panel and we can navigate
through it with transport controls.
This can be done by moving the position indicator in the Jog bar or
by using transport buttons. This way, we can select the position in the
record train that will correspond to the first frame of the clip we want
to create.
Then click on the IN button.
If the Clip Creation pane is not visible, we need to click on the Pane
display button first. And then on the IN button.
The next step is to create the End point of the clip. To do so, we can
use the jog bar or transport buttons to move to the desired position
and then click the OUT button.
The Timecode In and Timecode Out are displayed in the respective
zones.
Timecode In, Duration Field, Timecode Out.
IN and OUT button and New Clip button.
And the clip duration is automatically displayed in the Duration field.
The last step that remains, is saving the clip. To do so, let's click on the New Clip button.

The Save Clip window appears, allowing us to enter all the clip information.
In the Name field, let's enter the name of the clip.
With Keywords fields, we can associate several keywords with this clip so that it can be easily described. We
can select keywords from either a Keyword grid or a Dictionary which is accessible on the Keywords button
in the Main toolbar.
For instance, let's open a Keyword Grid.
Keyword Grid and Save Clip Window.
And from here on, clicking on a keyword will assign it to the clip we are creating.
The Interest Level buttons allow us to rate a clip. Four Interest Levels can be
defined, ranging from no stars to 3 stars. The background colour of the button
corresponding to the selected Interest Level is blue. The default value is set to
‘no stars.’
An interesting element to notice, is that we have the ability to send the clip that will
be created directly to a Target.
This is done with the Send to area.
Targets are destinations on the network which are defined in the system. For
instance, a target can be an editing system, a network storage or a connected
drive. If needed, several targets can even be selected.

But the clip can also be sent to one or more bins within the IPDirector database.
Bins provide another method of organising clips within the database in a
customised manner.
For more information about this topic, refer to the tutorial about the Database
Explorer.
We can also add metadata to the clip.
This information can be entered via the Metadata pane.
Metadata profiles can be used to facilitate metadata selection.
Metadata pane.
When all clip information has been defined, click on the Save button.
The clip is created. This is indicated by a green message appearing on the screen.
And the clip can be found in the 'Last clips created' field at the bottom of the Control Panel.
If we want to load the clip for playout on the Player channel, it's very simple to select it from the list.
It's loaded directly and we can click on the Play button whenever we want.

Clip Editing
The Control Panel also allows us to edit existing clips.
In order to do so, first we need to load an existing clip in the Control Panel.
There are several ways to do this.

It can be done by dragging a clip from the Database Explorer to the Control Panel - this part is explained in
the Database Explorer tutorial;

It can also be done by selecting a clip from the Last Clips Created dropdown menu as shown in the previous
sections;

or by entering the clip name in the Name field and pressing the Enter key.
The clip is immediately loaded on the Control Panel.
Enter the clip name in the Name field.
Once the clip has been loaded, some of its information is displayed in the panel.
As we have already seen, the timecodes In and Out, as well as clip
duration are displayed in respective fields.
On the other side, the clip duration is represented by the grey section
of the Jog bar.
At the left and right of this section, there are also two blue zones.
These zones represent the guardbands of the clip.
A guardband is a part of the media saved automatically with the clip.
Its duration is defined in the system settings. In our case it's 5
seconds.
When needed, guardbands can be used to extend a clip when its
initial duration is too short.
When the clip is loaded, we can change its duration by changing the
IN and OUT points.
To change the IN point, move the position indicator on the jog bar to
the desired position to define as the new IN point.
The Left Time Code Field reflects the actual position of the clip in terms of time code.
The Right duration field provides the clip's length from the indicator to the end of the clip. This is displayed in
yellow.
When we move the position indicator into the guardbands, we see that the indication in the Right duration field
has become white. The value that is displayed, shows the duration from the indicator to the border of the clip.

As we can see, the values are also shown in the Video display. Additionally,
the word IN is displayed preceded by a minus sign, indicating that we are
positioned before the clip's In point.
Positioned before the clip’s In point.
If we want to define a new In point, we need to click on the IN button.
The new In point has been defined and is indicated by a small green bar on the jog bar. The IN field and the
Duration field have also been updated.
Changing the OUT point can be executed the same way.
Use the jog bar to move the clip to the desired new OUT point. The Right
Duration Field is yellow when the indicator on the jog bar is positioned
before the OUT point.
The field is white when the indicator is positioned after the OUT point.
In this case, we also have the indication "plus OUT" on the Video display.
Positioned after the clip’s Out point.
Let's click the OUT button to define the new OUT point.
The new Out point is indicated with a red vertical bar on the jog bar and
the timecode and duration fields are also updated.

To save the changes we have just made, we need to click on the Update Clip button. And the clip has been
updated.
This is displayed via the new values of the IN field, Duration field, OUT field and guardbands.
All other information related to the clip can also be modified.
To do so, open the Clip Information tab and make the desired changes. If needed, associated metadata can also
be updated. Once this is done, we can click on the Update Clip button to save changes.

Moving within media
1. Moving Within a Clip
There are two ways to move through a clip and go to a
given timecode.
The first way is to move the indicator in the Jog bar until we
reach the position we are looking for.
The second way is to work with the Timecode field. In this
field, we can type in a new value. This value can be a
timecode value before the IN point, between the In and Out
points or after the OUT point.
When the value has been entered, we can press Enter to
validate.
As a result, the position indicator directly jumps to the clip's
specific timecode.

2. Moving Within a Record Train
The same operations are, of course, also possible with a Record train
when it has been loaded onto the Control panel.
Once the complete Record train has been stored on an EVS server, it
is possible to go back to any timecode on the train.
First, we need to load the record train on the Control Panel.
A simple way to do this is by right-clicking on the E to E button and
then selecting the proper Recorder channel.
Another method is to drag & drop the Recorder channel from the
Channel explorer to the Control panel.
From here on, we can move through the Record train with the same
operations.
Select recorder channel
via E/E button.
One thing to notice, is that the information in the Right duration field is
different. The value in yellow now shows the time difference between
the current position and the Live position.

Pressing the E to E button will jump back to the Live position on the Record train.

Playing out media
1. Playout Modes
The Play Mode button indicates how a clip or playlist will be played.
There are three different modes to play back media.

Normal Play mode: a clip is played from its IN point to
its OUT point.
Normal Play Mode.

Continuous Loop mode: in this case, the clip will be played in a continuous loop. This mode is
also indicated by the letter L on the On Screen display.
Continuous Loop Mode.

Bounce mode: the clip will be played continuously from its IN point to its OUT point, then back
from the OUT point to the IN point, and so on.
Bounce Mode.
The Play mode can also be selected by using a shortcut predefined in the Control Panel settings.
2. Delayed Record Train Playout
It is possible to play out a record train with delay.
There are two ways to do this.

The first way is to place the blue position indicator on the jog
bar at the desired position and click Play.

The second way is to type a delay value in the Right Duration
Field and press Enter.
Either way, the train will be played with a delay corresponding to the
selected value.

3. Playback Speed
The speed for playing back media per default is 100%.
This means that when we are playing back a clip, it will be played back at the normal speed.
But it is also possible to change the speed.
To do this, first we need to press the shortcut key predefined in the settings of the Control Panel. This will
open the Set Speed window.
Then, we can enter a speed value from 0 to 300%.
And click OK.
When playing back the clip, it will occur at the new speed.
This is displayed by the number located above the Play button.
