DivX A/V Synch

[davidb0000]

Here is the process I follow and it works perfectly for me most of the time:

1) Rip DVD
2) DVD2AVI to obtain AVI and WAV
3) Use VirtualDUB to synch. I use direct copy on video and full process on audio using MP3 codec. Then I save new AVI. I do not do anything else.

The problem: As the time elapses the video and audio start to get out of synch. Towards the end of the movie it looks like a chinese dubbed movie.

This happens for 4 out of 6 movies.

Any suggestions as to why this is occuring or how to synch them up?

2) DVD2AVI to obtain AVI and WAV

How do you get your avi after running DVD2AVI?

DVD2AVI is a DVD 2 AVI program. It makes it, quite well I might add(using DivX codec).

Maybe it doesn't always make avis too well? 8) I use DVD2AVI to create a project file and a wav. If I'm making (S)VCD the d2v file goes directly into TMPG. If I'm creating DivX then I use Gordian Knot to read the d2v file and create an avisynth file to frameserve to VirtualDub. I don't see why you are experiencing the problem with your method, though.

A couple of things you might try:

1. When you are adding the audio using the wav, restrict the audio bitrate to 96, 128 or 160. Using values in between can occasionally cause sync problems.

2. When you get one of these out-of-sync avis, first check that the wav file and the avi are actually the same length. If so, convert your wav to mp3 with any program - CBR, ABR or VBR, it doesn't matter. Then load the avi into Nandub (a modified Virtualdub). Video direct stream copy. Load the audio, direct stream copy and choose the (VBR) mp3 audio input. Leave the default interleave setting as is, and save the avi.
