TV Green Screen
by Arica West on Nov 10, 2010 at 11:32:07 pm
I am wondering if anyone could give me the basic steps or direct me to a tutorial for placing an image on a tv. Let me be more specific, I have a scene with a tv which one of the characters is blocking part of the tv. I need to place a video on that tv. The corners and the center of the tv are marked with green tape. Any suggestions how to go about this?

Unless your camera is locked down, you'll need to track the shot. Mocha-AE (included with CS4 and above) is a great tool for tracking planes like your TV screen. You'll use the tracking data to make your new video move with the camera as if it were placed in the scene. See Aharon Rabinowitz's tutorial on Mocha-AE Perspective Corner Pin effect.
Once the video is in the shot and the character passes correctly in front of it, you may need to tweak your composite to make it look real. Details sell the shot. See this thread on Adding footage to a TV for some tips.
