Atop
Function
This is similar to Over,
except that the background matte is used; the foreground will only appear where
there is background matte. Unlike Inside,
it will also keep the background information. Another way of putting it is that
it is the equivalent of Inside and then Over. Use this for applying
atmosphere effects to a foreground element, like putting smoke over a foreground
character.
