Question: Final Cut Pro X share fails with QuickTime Error -50
I'm facing a very annoying issue when trying to share my project from Final Cut Pro X. It used to work perfectly fine but now I'm getting consistently "QuickTime Error -50" after FCPX exported about 10% of my project. This can be reproduced with other project as well - one time I was able to export by restarting my machine but not anymore.
My configuration is a Mac Pro early 2008 with a ATI Radeon 5770. The only recent change I did to my config was to upgrade my old graphic cards to the Radeon 5770: do you think this can be the cause of this error?
Thanks for any help,
Mac Pro, OS X Mountain Lion (10.8.3), Radeon HD 5770
