Noob at green screen. Help please.

Hello everyone,

I’m trying to use a green screen in my SMA (stop motion animation) however, I have little experience with the green screen stuff.
Now what I’m trying to do is import a series of photos previously taken and place a background in but for the life of me I can’t figure out how to do it. Is this possible or not?

Thanks

Chroma keying can only be applied while shooting video. I’d suggest assembling the stopmotion movie in iStopMotion and then do the chroma keying work in iMovie: http://support.apple.com/kb/PH2245?viewlocale=en_US
