Screen recording won't export
Recently I got osx lion, and with it came quicktime 10.1 Today, I decided to try out the screen recording. I recorded it, cut some stuff out, and I had a pretty good recording. But when I try to export it, it refuses to work, saying the the operation is not supported for this kind of media. But when I check, I have the unedited version already there. Does anyone know what the problem is or how to fix it? Thanks!
Mac OS X (10.7)
