Selecting the key source and key fill
• As key fill for a downstream key, you can use a video signal input to one of
the VIDEO INPUTS connectors on the rear panel of the downstream keyer
(video input), or a signal generated by the internal color matte generator of
the downstream keyer.
Each of the maximum of four keyers has two color matte generators: matte
1 and matte 2. If the color mix function is off, matte 1 is always used.
• As key source you can use a video input or key input.
To use a color matte requires the optional BKDS-7320 Luminance Keyer and
Option
Border Board.
Use the following procedure to select the key source and key fill signals for
the downstream keyer.
