UPDATE NOTE: A new intructable that shows how to use a free, bigger and better program to add Green Screen effects to your movie has been made
Wanna make a movie like the pros? Using green screen editing? It's all free (besides the actual green screen itself) with this awsome program. Debug Mode's WAX is a video/picture/music editor. It has a drag and drop time line like in Windows Movie maker, so you can add pictures and music to your video.
I made this video with this awsome program. (Part's of the bluescreen still is shown because I did not have an even lighting)
This demonstrates how you can make an invisability cloak with chroma key. Just replace the bluescreen image with a picture of your video's background.Thanks to laferty
