Actually, a good H264 encoder should cope with what you're doing. The mainconcept encoder (which is very tweakable) would use scene change detection to automatically start a new GOP where the frame changes dramatically. What would happen to it on vimeo when it streams though is out of your control. Also, you could try giving vimeo a file with a much higher bitrate (say 30-40Mbps or so), it'll encode it down to a lower rate but at least it has a better start point.
