Applying a regional matte to a video filter
When you apply a video filter it affects the entire frame of a video clip.
There may be times however when you would prefer it to only affect a
certain portion of the clip, such as a highlighted area or a specific scene
in the background. You can do this by first creating an image or video
matte (see page 51) and then loading the matte into the Video Filters
dialog box. See the next page for details.
Note: If you do not have a matte to use then specifying a region has little benefit.
