Editor’s Toolkit: Using Overlay Mattes with Apple® Final Cut Pro®
The various mattes in the Editor's Toolkits are simply black and white
animations that are used to define transparency in composited video. These
animations do not have built-in alpha channel transparency like the many
full-color effects and transitions in the Toolkits and therefore a slightly more
complex to use.

The first video uses one of the stock
alpha channel overlay from Super Set 115 (ETK:5), while the second video uses a
black and white overlay matte from the same Super Set and a completely different
animated texture (Jump Backs animation #836 from JB21). |
To use a transition wipe (matte) in Apple® Final Cut Pro®:
1. Arrange your clips on the timeline (Figure 1):
* Video 3: background animation
* Video 2: overlay matte
* Video 1: video clip
Figure 1 - The timeline in Final Cut Pro® with an overlay matte.
2. Select the clip in V3 (the new background texture).
3. From the Modify menu, select Composite Mode > Travel Matte - Luma
(Figure 2).
Figure 2 - Select the clip in V3 and then Modify > Composite Mode >
Travel Matte - Luma.
4. In most cases, you will need to render the effect to see the final
results.
