Video Operations
Using a Key to Composite Video
(KEY)
You can turn a portion of the video transparent and composite it with the background video. You can
use luminance key with either a black or a white background, or a chroma key with either a blue or green
background.
Luminance key
This cuts out text or an image by turning the black
or white portion transparent, and composites it onto
the background video.
Black or white
Chroma key
This cuts out a video by turning the blue or green
portion transparent, and composites it onto the
background video. Using this, you can composite
only a subject that you are photographing against a
blue screen or green screen.

Here we explain the procedure for using luminance

material that is saved in the unit.

Press the [TYPE] button several times to select
KEY.
The KEY indicator is lit green, and the
composition results is shown in the preview
video (standby video).

INPUT 1 or 2 as the background.
The transition indicator (left or right) of the
selected background video is lit.
Each time you press the [1] button, the
background video being output as the preview
will switch.

disappears when you press the [2] button is specified
by the setting of the TRANSITION menu item “KEY
TIME.”
