Chroma Key

vary depending on each individual scene. You may need to go back to
earlier steps and readjust previous settings to optimize the key. Under-
standing what the chroma key controls do will help you decide what
adjustments are required for your individual situation.

Primary Suppression
Primary suppression is the most critical chroma key parameter, and the
easiest to set. Auto Setup should take care of this, but manual adjustments
can be made if desired. If primary suppression is set wrong, however, it will
be impossible to achieve a good chroma key with the other controls.
