For some reason, it is difficult to create an iPhoto smart group for movies. You can’t specify a group based on file type, and there isn’t a simple “is movie” or “is photo” type toggle. To make a group that contains only movies, create a title match that contains .avi or .mov, whatever format comes off your camera.
I’m on iPhoto 6, so it is possible this has been fixed in later releases.
