Intraframe Example: Creating a Matte Key Effect
When you apply the AniMatte effect and create a matte key, the shape and location of the matte
remain fixed over the course of the segment. The parameters of the matte are the same at both the
first and last keyframes in the segment.
To apply a two-layer matte key:
1. For this two-layer effect, edit the image you want to use as the background onto one track
and the image you want to use as the foreground onto the track above.
For more information, see “Creating and Editing Sequences” in the Help.
2. Enter Effect mode, for example, by clicking the Effect Mode button.
For more information, see “Entering Effect Mode” on page 39.
The Effect Editor opens.
3. In the Effect Palette, click the Key parameter category.
4. Drag the AniMatte Effect icon from the Effect Palette to the upper track in the Timeline.
5. Press the Home key to go to the beginning of the clip. Ensure both the first and last
keyframes are selected.
6. In the Effect Editor, click the Reduce button to view the image in the Effect Preview monitor
at 75 percent.
This makes it easier to include the outer edges of the footage in the traced area.
7. Click the Curve tool.
8. In the Mode parameter category, click the Fast Menu button, and select Key In.
9. Click the image, and drag to draw a matte with freehand capability.
