Index card with one page:
Page Mode 1/2
V + V Channel 1 and 2 process both a video signal. The key signals for
both channels are generated internally in the DVx. Both channels
can be controlled individually.
V + K In this mode Channel 1 processes the video signal and channel 2
the key signal (flying key mode). Channel 2 can not be controlled
directly, the control parameters of channel 1 are used.
Note:
Since in the actual software also the input source for channel 2 is set by chan-
nel 1. This would not allow you to select e.g. ”chargen video” for channel 1
and ”chargen key” for channel 2.
To allow different sources set in the Input index card Inp.–Type to ”no x–pts”.
Page Mode 3/4
V + V Channel 3 and 4 process both a video signal. The key signals for
both channels are generated internally in the DVx. Both channels
can be controlled individually.
V + K In this mode Channel 3 processes the video signal and channel
4 the key signal (flying key mode). Channel 4 can not be controlled
directly, the control parameters of channel 3 are used.
Note:
Since in the actual software also the input source for channel 4 is set by chan-
nel 3. This would not allow you to select e.g. ”chargen video” for channel 3
and ”chargen key” for channel 4.
To allow different source set in the Input index card Inp.–Type to ”no x–pts”.
