Sound & video length mismatch

[Vertigo1]

Help! :)

I ripped a DVD using DVD2AVI, and re-encoded the video using CCE.
The source material is PAL at 25fps.

When I load the MPV file that CCE spat out, and the AC3 file that DVD2AVI produced into DVD Maestro, the lengths are different. The difference is around the 4% mark, which leads to believe that it's in some way frame-rate related, but I don't know what I'm doing wrong.

Any and all help appreciated

I had a similar experience when I tried to re-encode the extras on Spiderman. This is an NTSC format.

Just as an experiment I took one of the re-encoded m2v files and the matching ac3 file and authored them in IFOedit. Sure enough the video and audio where out of sync. The delay seemed to get even worse further down the timeline. When watching it the video seemed like it was playing in slow motion.

When I added the files to the track editor in Scenarist, the video file was longer than the audio file. However, when I added the original demuxed m2v file, the video and audio matched up perfectly.

For whatever reason, CCE 2.50 SP made the m2v file grow when it re-encoded it.

I used the exact same templates when I re-encoded the main movie files, but with different avg and max bitrates of course, and the re-encoded m2v file matched up perfectly with the ac3 soundtracks.

There is definitely something screwy here. I'm still scratching my head on this one.

This was my first movie that I have backed up using Scenarist. Since then I haven't seen this problem with any other movie of mine. I haven't changed the way that I re-encode. You would think that if I was doing something wrong it would carry over to my other projects.

Has anyone else had a problem re-encoding the Spiderman extras?
