I exported a Master File from FCPX and when I play it back everything is perfect. I drop the MOV into Compressor and select Blu-Ray.264 and .ac3. After It processes, when I try to put together my BluRay disc I notice that over time the audio and video have fallen out of sync. How can I correct this ?
Ok, I made sure all the audio is 48kHz but I'm still having this problem. If I export to a Master File, the audio is in sync. But once I convert to .264 the audio starts to fall out of sync as the video plays on. Any suggestions ?
