Chroma Key Composition
Normal mix and additive mix
In creating a chroma key image, either a normal mix or an additive mix can be
used. To select which, use the Type >Chroma Adjust menu for the keyer.
Normal mix:
The foreground is cut out with the key signal, and then combined
with the background, which has also been cut out with the key signal.
Additive mix:
The background, which has been cut out with the key signal, is
combined with the unshaped foreground. This is effective for a natural-
looking composite when the scene includes glass or other translucent
objects.
Plane function
In an additive mix, the foreground is not shaped by the key signal, and
variations in the (blue) background appear in the composite image. To prevent
this, it is possible to set a particular luminance level for the background, and
any parts below this level are cut forcibly.
Composing an image by chroma keying
There are two types of composition for chroma keying: normal mix, and
additive mix.
