Creating a Matte Key for Use with 3D Effects
A matte key is an effect made up of three components:
 | |
High-contrast image or matte
|
 | |
Background image (the image that shows through the lightest part of
the matte)
|
 | |
Foreground image (the image that shows through the darkest part of
the matte)
|
You can promote real-time 2D Matte Key effects (graphics imported with an alpha channel) to 3D effects and apply additional parameters, such as Shape Wipe effects, or X, Y, and Z positioning.
 | |
You cannot promote matte keys created using the Matte Key effect from the
2D Effect Palette to a 3D matte key.
|
To create a matte key for use with 3D effects:
1. | |
Import a graphic file containing an alpha channel.
|
The Avid editing application creates a Matte Key clip when you import
the file.
2. | |
Edit the Matte Key clip into your sequence as an overlay.
|
3. | |
Ensure that Render On-the-Fly is enabled (displays a check mark in
the Clip menu) so you can see the matte key as you are working
with it.
|
5. | |
Select Tools > Effect Editor to open the Effect Editor, and apply
changes to additional parameters to achieve the effect you want.
