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 results.
Note: The Set Matte effect was originally developed for After Effects.
It is included in Adobe Premiere Pro 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 Key effect.
- Take Matte From Layer
- The video track to use as the replacement matte. You can specify any video track in the sequence.
- Use For Matte
- The channel 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.
