"The playback was at a full 12fps, and actually looked like video. I endcoded the same .mov file several times in Flix, and had to get up to a 2.1meg file"

I've encoded 30 second .mov files in Flix at *22* fps, with far better resolution than your examples, same dimensions, coming in around 2 mb's...the jury's still out on this one.
