Final Cut Pro X never finishes export (sharing)
I am attempting to export my finished project to a .MOV file so I can burn it to BluRay via Toast. A process I have done multiple times with previous projects. However this time my Sharing progress bar freezes at 81% and never finishes. I have tried multiple times to export the file and it freezes at a different spot each time (37%, 78%, etc.) I let FCPX run over night to no avail, when I go to sleep it is at 81% and when I wake up 8 hours later it is still 81%, so I give up and silently curse the lack of error messages.
I have tried many of the suggestions from other discussions on here from people with similar problems, I've deleted preferences (using Preference Manager), reinstalled, deleted various folders in my library folder, none have made any difference.
More details in case it helps:
I export by going to File:Share:Export File...
Select Pro Res (HQ)
open in Quicktime when done
I don't really know what other options I have other than to hope one of these times it makes it through. Any suggestions are appreciated.
It would be nice if FCPX had more feedback as to what it is doing. It also would be nice if it worked.
