Adobe After Effects Frame-By-Frame Editing I am currently editing a clip in After Effects. We had a very limited supply of green screen so I am now having to edit some of the white wall too. The thing is, the actors move around, not allowing me to clip out these parts.

I was wondering if there was a thing in After Effects that allowed me to break up the clips so that I can work around the actors in certain time intervals and get the white wall to be transparent.

Thanks!
Have you used the Roto Brush? It was designed for situations like these.

For those unfamiliar, there is a nice concise tutorial here on how to use the Roto Brush.
