PreAmp
FG and BG PreAmp
The
FG
and
BG PreAmp
panels contain various color, brightness and white balance adjustments for the foreground and the
background. These adjustments may be used to compensate for non-ideal inputs or to achieve speical tint/lighting effects. The
FG
PreAmp
adjustments are processed before chromakey and will affect the chromakey. Therefore, once a satisfactory chromakey
result is achieved,
PostAmp
should be used on the processed foreground (PFG) or the composite result (Comp) instead of
FG
PreAmp
. On the other hand,
BG PreAmp
can be used independently of the chromakey.
Default
Clicking the
Default
button changes all adjustment controls to their default values, which are set to bypass the foreground and the
background without any
PreAmp
processing.
White Balance
A cursor-picking dialog appears when the
White Balance
button is pressed. Simply select an appropriate pixel as the reference
color.
