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
“Creating image and video
mattes” on page 114 ) and then loading the matte into the Video Filters dialog box.
See the next page for details.
If you do not have a matte to use then specifying a region has little benefit.
