Create transparency with a keying effect
To create transparency wherever a specific color occurs in a clip, apply a color-based keying effect. These effects are
commonly used to remove a colored background.
1 In the Tasks panel, click Edit, and then click Effects.
2 Choose a Keying effect (or Chroma, Blue Screen, Green Screen, or Non Red).
3 Drag the effect to a clip in the Timeline or Sceneline.
4 (Optional) Click the Edit Effects button at the bottom of the Tasks panel to open the Properties view, and expand
the effect name to view and edit the effect’s options.

Create transparency with the Track Matte Key effect
1 If you haven’t already done so, add the matte file to the project: Click Organize in the Tasks panel, and then click
Get Media. Navigate to the matte file, and click Open. The matte file should preferably contain only a single shape
(for example, a star or a flower).
2 Add a background clip to a track in the Timeline.
3 Add the clip you want to superimpose over the background clip to any track higher than the background clip. This
is the clip revealed by the track matte.
4 On a third track, add the clip that serves as the matte. (If you need to add a third track, drag the matte to an empty
area in the Timeline above the highest video track; a new track is automatically created.)
5 In the Effects view, expand the Video Effects folder and the Keying category folder, and drag the Track Matte Key
effect to the superimposed clip (the clip above the background clip).
