I had some serious problems uploading some edits up on vimeo a couple of months ago, they would say they have uploaded but nothing would play, annoying when i tried to reload them vimeo said I had reached my weekly HD limit. I think the files size was too large (even thought below the max limit). So I exported in H.264 and they uploaded fine later that week.
how do i check that paul? really not that great with computers.... No, it was just cheap digital camera footage and not HD or anything. going to try again later with another edit and see.cheers
