I have a number of different images of my face, and I want to overlay them on a live DV feed, so I can match up my features to the people I'm taking new pictures of (same position, etc.).

Is there a program that will let me select an image file to put on top of a video capture feed, that'll also let me take pictures like a stop-motion program (I don't even need to capture video, just take still frames)? The issue with stop-motion is that the images of my face come from a previously-recorded live video.

I have After Effects and Flash, but I don't think either of these will do it. Can anyone help?
