Hey,
I've ripped Avatar from BD to a single .m2ts file, then re-encoded the video stream to h264. After stripping out the dts audio track, I mux the streams together using:
The command completes successfully, and at the start of the film, audio appears in sync. However as the film goes on, audio gets more and more out of sync with video, until it's about 0.5s out by the end.Code:mkvmerge -o Avatar.mkv --default-duration 0:24000/1001fps -A Avatar.m4v Avatar.dts
the audio file lasts 9701.72 seconds, and my re-encoded video has 232,591 frames. This gives a framerate of 23.974202513fps, rather than a framerate of 24000/1001 (23.976023976).
Am I missing something? Anyone else had similar issues?
