LESSON 15 Exploring Compositing Techniques
3
Drag the clip entitled brown matte to the Video 2 track directly above the video 
clip in the Video 1 track. Stretch the brown matte clip so it’s the same length as 
the video clip in the Video 1 track.
The matte completely covers the video. If you play the clip in the Program 
Monitor, you’ll notice that you cannot see any of the video on Video 1 track 
because the brown matte clip in the Video 2 track is covering it.
4
Select the brown matte clip, and expand Opacity in the Effect Controls panel.
5
Use keyframes to set an Opacity effect of 100% (opaque) at the beginning of the 
clip and an Opacity effect of 0% (completely transparent) at the end.
6
Play the clip.
The brown gradually becomes less opaque and more like a tint. Finally, it 
disappears altogether.
7
Right-click (Windows) or Control-click (Mac OS) the brown matte clip, and 
then choose Copy.
You’ll paste the Opacity parameters on another clip to save a few steps.
8
Right-click (Windows) or Control-click (Mac OS) the brown matte clip, and 
choose Clear to remove the clip from the Video 2 track.
9
Drag the gradient circle to Video 2 track, and stretch the gradient circle clip 
to the same length as the video clip in Video 1.
