vdub makes audio and video out of synch

[asdf]

ok, i captured one of my VHS onto the computer and im hoping to transfer that to a DVDr. Altogheter, the 10 avi files that were split apart when capturing are about 21 gigs. So first i tried to join all the parts together using Virtualdub. I simply appended the parts and saved the movie with direct stream copy on video and audio. It worked fine and the resulting avi was 25 gigs. The audio and the video were good at the beginning until later on in the movie, the audio and video gets out of synch. Anybody know how to correct this?

I think you need to use Gold Wave to adjust the audio so it lasts as long as the video. The function is called Time Warp. In the Effects menu.

The proper use of Goldwave to fix this, is outlined here: http://club.cdfreaks.com/showthread.php?s=&threadid=59487

The FREE way:

Before making any changes, like cutting out unwanted sections:

Open your AVI in VirtualDub.

Under "Video" select "Frame Rate".

In "Source rate adjustment" select "Change so video and audio durations match, OK.

Under "Video" select "Direct stream copy".

Under "File" select "Save as AVI".

Save to the other hard drive.

Check your new AVI's file info and you will see that the audio and video are the same length.

Go ahead and cut the unwanted sections.

Save back to the original hard drive making sure the video "Direct stream copy is still checked".

This will probably produce an AVI with a frame rate of 29.968 or thereabouts which is still within the normal parameters of most encoding programs (TMPGEnc has no problems with it).

thanks for your help "almost human", but i dont think you understand what im doing. Im not trying to edit the avis. I want to put the avis together because they got split apart when it was captured. So do i append the avis and then select video and so forth or do i do that with each avi before i append them.

The split AVI's need to be merged back into a single, VirtualDub will only work with a single. Use the same program you captured with to recreate the sequence of clips in order, then output save as an AVI file. Depending on the program you used, you might have to tell it to "make settings match file type" to keep from re-encoding. After this then follow my previous suggested fix.

VirtualDub will only work with a single.

Huh?
Virtualdub has already "worked" with his multiple clips, and joined them, that's not the problem.
Progressive audio desync is a problem, and I linked to a guide that works great for resyncing audio.
Once it's been checked in virtualdub (no need to rejoin the streams), the files can be encoded together or separate. Join during encoding, or authoring.
To check audio sync in vdub, load the avi video, then select Audio, wave audio. Advance to near the end of the file, and check for sync by hitting the Play 0 arrow (output).

thanks everyone.
