You can perform this procedure on different objects, or mattes in a segment or
transition, to create an effect in which the objects or mattes pop onto the
screen at the intervals and positions you determine.
Feathering
Feathering adds soft edges to a painted object or a matte key. Adding a
soft edge can make a composited object look more natural against the
background. Feathering softens edges by diffusing the border of the
object by the pixel width you want.
