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.
Primary Suppression should be set while looking at the foreground. Ideally
the backing color will appear as a small dot on the vector scope and a per
-
fectly flat line on the waveform display, but this never occurs due to set
lighting variations, shadows, etc. This means you will need to pick the best
suppression for the overall look of the key.
1. Touch the stage 1 Pri Suppress data pad, if necessary, to activate these
controls (
Figure 184).
