eh....
what you need to do, is to learn how to compress your video. for that resolution, you could get it down to at least below 1 mb. and make your flash the same size as the video. its in the properties box when your not selecting anything.
so...you look pretty good at 3d. if i could hire you for something (sorry no pay), i promise it will be worthwhile. more info if you contact me. maybe ill contact you, whatever. i deserately need an animator, cause i dont have time anymore to work on stuff in 3d.
