Asset Matte Movie

The asset matte movie is required only when an asset movie that does not include an alpha channel is used by the transition. Having a separate asset matte movie is particularly useful when the asset movie is normal video (as opposed to an animation).

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

The asset matte movie needs to be monochrome, with white identifying the asset movie video to use, and black identifying the places where the start or end frame video appears. You can also use levels in between white and black to set a transparency and add soft edges.
