In the previous chapter we've stabilized this footage which was shot on a…green screen stage.…The next thing we need to do is key out the screen so that we can see our new…background behind it.…The process of keying is picking a color such as this screen background, making…it transparent, but making sure that the action we want to keep these actors…remain opaque, and preferably with a nice anti-aliased or feathered edge at the…boundary between the two.…Now if you did not follow along in the previous chapter, but you do have access…to the Exercise Files go into the Comps folder and open up 05-Keying*starter3.…
