Q: Compressor issue, keep getting Failed: QuickTime error.-50. Anyone knows why?

What are you attempting to do when you get this error? Are you working in Compressor or FCP?

I have this problem too, I sent a 1hr long video to Compressor from FCP and trying to save it in H.264

If works for a few hours and then says it failed.

Any help would be much appreciated!

Then don't use the send-to-Compressor workflow. Instead, export a master file as Pro Res – a very fast process if things are working as they should. Try a vet short section of your movie to test. Then use Compressr to encode the file to h,264.

When I ran into the Quicktime Error -50 issue, it was a corrupt source movie. When I played the movie in QT Player, it would stop playing part of the way through the clip, but the time code would keep on ticking and the play head would keep moving.

If I set an out point in Compressor to cut off the corrupt part of the footage, it compressed perfectly without any error.

Sometimes the issue seems to be Final Cut initiating an auto render in the background while compressor is also rendering your batch or file. What has worked for me is ensuring that the timeline is closed in Final Cut or auto render is disabled before attempting a compressor export. Before a large render I often 1) Disable auto render in FCP 2) Close open timelines so that only the bins and media are open and 3) Disable screen saver in preferences (just for luck). Try to keep background processes in general from initiating while compressor is in motion.
