Chroma Key Menus
[EDGE CONTROL] —Selects a multiplicative or additive (matte-
style) chroma key. Multiplicative works best when the key edges
are soft, such as when smoke or fog is present in the foreground.
Additive works best when you are striving to preserve as much
realistic detail in the key edges as possible.
