Since upgrading to Mountain Lion I have found that iMovie crashes and quits when trying to share a movie to Youtube. I've no idea why this is happening but it's consistent. Anyone else have this problem?
YES, I've been having this issue and can't find a fix. I try to upload a movie and at some random point in the process it just hangs. Any help would be greatly appreciated!
As if this isn't bad enough I can't even successfully upload a movie via my browser that I've already exported to Quicktime. Each time I submit it Youtube keeps saying it's uploading 2 movies. Then at the end of the upload sequence I get an error page and two endlessly hanging upload thumbnails. I never had this problem when I used the "Share to Youtube" function in iMovie.
