Virtualdubmod + direct stream copy + vista x64 = out of sync + other issues

[Gruelius]

Hi all,
If i have a pretty much standard xvid with mp3 audio, and i go to a random offset, delete up to that point, select 1 min forward and then delete after that point, when i save it with direct stream copy usually it will end up being 1min long and audio out of sync with the video jumping forward a bit, then i save it again and it will become about 1 min 2-8 seconds long and in sync.

The other thing it might do is create a file 2x the size it should be but in sync and the correct length.

Ive also had problems with files being oversize with gknot, i did a bit of researching and found old posts talking about newer xvid revisions not supporting vfw.

atm im just using my other xp machine to use vdubmod but is there a way to get it working on my vista x64 setup? cheers

Make sure to cut on keyframes, and try Avidemux. And yes, drop VFW encoding entirely if possible - switch to a newer frontend like MeGUI, Staxrip, RipBot264, etc.

Make sure also that when you open the file initially with Virtual DubMod that if you're given a message about rewriting the header that you select "No."

I know I'm probably not really adding anything useful to this discussion, but since I have the same problem, I'll post anyway. Maybe it's useful, perhaps not.

Almost same situation, though I use plain VDub, and encoded the audio myself

I have found that the MP3 audio stream is of a different length than the original uncompressed.

No matter if VDub or an outside program(Goldwave) encoded it.

I suspect that the MP3 codec was at fault, as I used the old radium mp3 codec which isn't designed for 64Bit.
I'm currently trying to find a 64Bit codec...
