I'm trying to figure out how to create a video layer in FCP that divides all color into either black or white, and then makes the white transparent. Here's an example: (note that because the forum background is white, this appears black and white; on a green background, for instance, it would appear black and green). I want to be achieve that look with a video. The black / white threshold needs to be customizable. I have Final Cut Pro, Magic Bullet Looks, and After Effects at my disposal, as well as a modest budget if there's a shareware/retail plugin that can do it. Any pointers? edit -- to further complicate this, a way to separate out the background, preferably without shooting in front a green screen, would be useful as well.
