How to Edit with Chroma Key / Green Screen Videos

http://geeks.pirillo.com - http://live.pirillo.com - Im still surprised at how many of you accepted the first community challenge I threw out regarding green screens! Since I thought the response was so great, I bought a green screen of my own so we can do these once a week! Do you know how to edit these videos? http://chris.pirillo.com Distributed by Tubemogul.
