I have a clip that is about an hour long. It plays fine in the timeline but when I save it as a QuickTime file the audio goes out of sync about a third of the way in. It has done this after 4 attempts. The audio goes out of sync in the same spot each time--there is a noticeable 'skip' in the QT file always in the same spot.. Any suggestions how to fix this? Thanks.
I checked and the clip is not h264 but HDV 1080i60 which I imported from tape into FCP. I use this same workflow all the time and I have never had a problem like this. It plays in the Viewer and the Canvas correctly with no audio sync problems but when I export it to QuickTime movie it goes out of sync in the same spot. ???
This seems to have fixed the audio sync problem but when I export to a Quicktime movie from FCP my file size is HUGE, and thus gives me some extreme processing times in compressor. My original file that was out of sync was 1.68 GB, but now my QT file exported using the ProRes file is 30GB. Any suggestions on how I could bring my files sizes down and thus my compressor processing times down as well. I'm exporting a QT mp4 using h264. The clip is about an hour long.
