Use the following steps to set the background mode:
1. In the Layer Functions Section , press BG/DSK . The button blinks and the BG/
DSK Input Setup Menu appears.
2. On the Mode line, set the desired mode:
~
To work in background mode, select BG . This enables you to use a color
matte, a still frame, or a live DVI source as the background layer.
~
To work in DSK mode, select DSK . This enables you to use a still frame
or a live DVI source as the downstream key. You can also set a
background matte color, which will appear under a PIP or Key.
BG/DSK
Tip Ensure that you set the background mode before your live
event begins.
Note The PresentationPRO-II system enables you to switch
seamlessly between
BG and DSK modes during a live event.
Remember, though, that any pending background (or DSK)
will not be seen until it transitions to Program, so it is to your
advantage to preset your background colors, DVI sources,
key clips, etc.
