Background Matte Movie

The background matte movie can be used in one of two different ways:

The background matte movie must have the same name as the transition asset folder, followed by “-backgroundMatte” and can have an extension. For example, if the transition asset folder’s name is Spinning DVD, the background matte movie could be named Spinning DVD-backgroundMatte.mov.

The background matte movie needs to be monochrome, with white identifying where the start frame video appears, and black identifying where the end frame video appears. As a general rule, the background matte movie should start with a full white screen and end with a full black screen. You can also use levels in between white and black to set a transparency and add soft edges.
