Video Composition Operations

Compositing Using Split

This composites two video streams in a split screen.
The video at the PGM (video currently being output)
is displayed above or on the left, and the video at the
PST (video to be output next) is displayed below or
on the right.
MEMO
5 While compositing of the video is in progress, the video
switches with cuts regardless of the selected transition
effect.

Composition Type" (p. 22) to select "SPLIT-VS,"
"SPLIT-VC," "SPLIT-HS," or "SPLIT-HC."

Compositing Using DSK

This takes video composited upstream using PinP
or the like, and performs further downstream
compositing with text or images.
Using DSK (downstream keying), you can switch
the background video while text or images remain
displayed.
Setting the Extraction Color
By factory default, the extraction color for DSK is set
to "BLU-C.KEY" (blue).
If you want to use white, black, or green as the
extraction color, then change the setting.
1.
Display the SETUP menu (p. 12), then select
"KEY TYPE."
2.
Use the A/B fader to specify the extraction color to
use when compositing.
