Compositing Using DSK

DSK composition.
If you want to use text or images input via a
different channel, go to the SETUP menu, and at
DSK (page 7/16), use “SOURCE CH” to change the
input channel.
If you want to perform compositing using a
captured still image (p. 21) or a still image sent
from V-1SDI RCS dedicated software, change the
setting to “STILL.”
