Nesting a Matte Key Effect
A Matte Key effect uses three layers of video to create the effect.

To nest a Matte Key effect:
| 1. | |
Create a sequence with the background video on track V1.
|
| 3. | |
Open the Effect Palette by doing one of the following:
|
| |
In the Project window, click the Effects tab.
|
|
| |
Select Tools > Effect Palette.
|
| 4. | |
Click the Key category.
|
| 5. | |
Drag the Matte Key Effect icon from the Effect Palette to the segment
on track V2.
|
| 6. | |
Click either of the Segment Mode buttons (Extract/Splice-in or
Lift/Overwrite) below the Timeline.
|
| 7. | |
Double-click the Matte Key Effect icon in the segment.
|
The Timeline expands to display three nested tracks (1.1, 1.2, and 1.3).
By default, nested track 1.3 contains the same image segment as track
V2. Nested track 1.2 is empty (foreground filler track). Nested track
1.1 (background video) is also empty.
| 8. | |
Click either of the Segment Mode buttons (Extract/Splice-in or
Lift/Overwrite) again to leave Segment mode.
|
You can now edit the nested tracks.
| 9. | |
Edit the foreground image onto nested track 1.1.
|
| 10. | |
Click either of the Segment Mode buttons (Extract/Splice-in or
Lift/Overwrite) below the Timeline, and then double-click track V2 to
collapse the nested tracks.
|
| 11. | |
Click the Record Track Monitor button for track V2 in the Track
Selector panel.
|
You should see tracks V1 and nested track 1.1 through the high-
contrast image on track 1.3.
