I am working on a short video for a play and I would like to take an image I have and turn it into a video clip (i got this, he he) and then using some program key out the mouth (i painted it blue) and then place my mouth instead. I was able to do this but the two do not blend and hence do not look as I would like them too. Is there a way to make a gradual key so that my mouth and the face can blend better? Or do I have to just try to recreate the lighting of the face pic? Any suggestions are well taken. Thanks!
