Move the joystick counter-clockwise with the Z button in the joystick lit to make a
chromakey. Once the joystick is moved counter-clockwise, cursor selected color should
be ignored and a chromakey should be automatically composited with background on the
preview line output. Even if SELECT in the menu is set to OFF, the designated color is
removed, and the chromakey can be created.
5-10-3. Chromakey Adjustment
If the results of your chromakey are still not the best possible, you may need to additionally
adjust clip and gain levels to adjust the key cut parameters. You may also need to apply color
suppression to get the optimum possible chromakey results. Color suppression settings let
you adjust how color is cancelled and ignored when your chromakey is made.
Edge adjustment
Fine adjustment can be performed for the key edges when they do not appear smooth. The
EDGE item of the AUTO CHROMAKEY menu can be used to make settings. The settings
can be made using POS or LEFT/RIGHT.
