The document discusses using a green screen to film footage and then keying out the green to make it transparent, allowing a background to be added behind the filmed content. The author filmed with a green screen, used a keying filter to remove the green, cut out the needed footage, and added a background behind the green screen footage to create the desired effect of the background showing through the now-transparent screen.
