I've been trying to export various movies in Quicktime X with no luck. I've tried .mov, .m4v, .avi files with no luck. Here are my main issues: 1) When exporting I only get three options: 480p, iPod touch & iPhone 3GS, or audio only. Is this really all I can export in? 2) Every time I try to export a file after I trim it I get an error. It will export with the whole movie, but not once it's been edited. Attached are the error messages that I get in various forms.
