You must unlock the Just Control Configuration window and stop the channel(s) to be able to make any changes.
New Layer: Adds a new Video, FX, Simple FX, Event or Audio Layer to the selected Channel.
Move Up/Down: Moves the selected Layer up or down. The final visual output will be in the order defined here (top to bottom).
ID: Unique ID, used to identify the Layer within Just Connect and the XML Playlists.
Name: Name of a Layer. Double click to change it. The Layer names will be displayed in the just:live/just:play user interface. Use less than 8 characters for just:play and less than four characters for just:live user interface. Otherwise the name will be shortened.
Layer Options / Status: Once and Infinite Graphic has been defined in the Inspector of the Multi Viewer, the chosen graphics element is shown here.
Primary Just Out Engine: Select a Primary Engine for each Layer you want to use with this Channel – otherwise the Layer will not be active. By default, a channel comes with one Video, two FX Layers, one Simple Graphics Layer as well as with an unlimited number of Audio Layers which can be upgraded to any number of Layers, depending on the power of your host machine(s) and the speed of the disks.
Redundant Just Out Engine: If there are two Just Out engines on two different machines available they can be configured as Primary and Redundant engine which means that the information from Just Connect will be sent to both engines and therefore the two engines are playing out the same content synchronized all the time.
Playlists which have been made before a layer has been added will show the new layer, but you will not be able to add elements to it. Make a new playlist to be able to use the new layer.
Removing a Layer
Make sure you have selected the proper Channel in the Channel List.
Click on the Layer you would like to remove.
Press the backspace key.
Accept the warning dialog to remove the Layer. This cannot be undone.
