The purpose in adjusting
Clip H
i and
Clip Low
is to cause the proper hole to
be cut in the background. All areas of the backing color should be full back-
ground while all areas of the foreground should make the background
completely invisible. The easiest way to do this is to observe the key signal
while making your adjustments.
The smaller the difference between
Clip Hi
and
Clip Lo
, the higher the keyer
gain. High gain amplifies noise present in the transition between trans-
parent and opaque. The correct setting is with
Clip Hi
and
Clip Lo
set to just
barely achieve opacity and transparency, respectively.

3.
Adjust
Clip Hi
so that all areas of the foreground objects are white. If
Clip Hi
is set too low (too far clockwise), much of the translucent areas
will be forced to be fully opaque, hardening the key and darkening the
transition area between background and foreground.
