I recently bought FCE and I edited my first project and exported it with Quicktime as a .mov file. I've tried uploading my project to Youtube, Vimeo, and Facebook, but all three sites keep telling me the same thing. Apparently there is something wrong with my file and that it's either not a video file or it uses codecs that are not understood by their specific site. I don't know too much about this so if anyone can help me that would be great. Oh and I own the Mac OS X which is the computer it is installed in
