I use Photobooth on the Imac to record small videos and they playback just fine when I use the quicktime player, but when I upload it to youtube,the video moves regular speed but the audio is in extra slow motion. I have read that it has something to do with frames per second. I thought converting it would work but when i uploaded the video file to convert it, i noticed that the Frames per second was only 15. Ive used photobooth before to upload videos and it worked fine.....does anyone know what the problem is?
