Set Matte effect
The Set Matte effect replaces the alpha channel (matte) of a clip with a channel from a clip in a different video track.
This creates traveling matte effects.
Note:
The Set Matte effect was originally from After Effects and intended only to provide compatibility with projects
created in earlier versions of After Effects that use the Set Matte effect.

To create a traveling matte using the Set Matte effect, set up a sequence with two overlapping clips on different video
tracks. Apply the Set Matte effect to one of the clips and specify which clip provides the replacement matte. Although
you can use Set Matte for a traveling matte, it is easier and faster to create traveling mattes by using the Track Matte
effect.
Adjust the following controls for the Set Matte effect:
Take Matte From Layer
Specifies the video track containing the clip to use as the replacement matte. You can specify
any video track in the sequence.
Use For Matte
Specifies the channel of the specified clip to use for the matte.
Invert Matte
Inverts the transparency values of the matte.
Stretch Matte To Fit
Scales the selected clip to match the size of the current clip. If Stretch Matte to Fit is deselected,
the clip designated as the matte is centered in the first clip.
Composite Matte With Original
Composites the new matte with the current clip, rather than replacing it. The
resulting matte lets the image show through only where the current matte and the new matte both have some opacity.
Premultiply Matte Layer
Premultiplies the new matte with the current clip.
Solid Composite effect
The Solid Composite effect offers a quick way to create a composite of a solid color behind the original source clip.
You can control the opacity of the source clip, control the opacity of the solid, and apply blend modes all within the
effect’s controls.
