Hey Skeetshooter A good way to composite video layers is to render each seperate element with the background set as ALPHA then load them into your editor as "pre-multiplied alpha". I find it to be more effective then trying to "key-out" blue or green. When you configure your codec (quicktime I'm guessing) be sure to set it to RGB + Alpha. If everything is set correctly, the background will automatically be transparent when the clip is load in. later Joe
