Resyncing audio

[trooper11]

Hi.

I was looking for some help with an audio sync problem Im having. I have a video file and I can tell that the audio is off by about 450ms throughout the entire file.

Now what program can I use to adjust the entire audio stream by that much to correct the offset? Can I do that in Vdub or will it need ot be something else? Thanks

What type of video file?
Avi, MPEG-2, RM, Quicktime or anything else

virtualdubmod. select srteams, right-click on your audio stream and select full-processing. you should now have more options on the right-click menu. inside one of these is what you seek. I don't have it on this pc, so this is from memory

You have to load the file into virtualdub and select video>directstream copy then streams>stream list and right click on the audio stream you want to correct and choose interleaving, then under audio skew correction you can set the audio to play before or after the video. If audio is a second ahead of the video then enter 1000 ms or if it's a second behind enter -1000 ms(1000 ms being 1 second) don't put a + before positive values because it won't work, click on ok and go to file>save as and enter a file name and save it. Make sure you use direct stream copy or the file will be compressed again and you will lose quality. The whole procedure shouldn't take more than an hour or so depending on how quickly you find the right audio delay.
I use virtualdubmod but the process is basically the same for virtualdub.

Hope this helps, peace.
