autogk...video/audio sync problem

[justinax]

Hi......i this is my first post in this forum.........i m new to all this video stuff...

i encoded a dvd into AVI using autogk..........when i played the video i noticed that the video leads the audio by a little more than 2 seconds.......


can somebody please help me........?

By the way the avi's were created from a dvd from my personal collection.....

Hi!


A) If the difference between audio and video is constant throughout the video:

Load the file into VirtualDub, VirtualDubMod, or NanDub.
Set BOTH "Video"(VirtualDub, VirtualDubMod and NanDub) and "Audio" (VirtualDub and NanDub - VirtualDubMOD>"Streams>"Stream list") to "Direct Stream Copy".
From the "Audio" dropdown menu, select "Interleaving" (For VirtualDubMOD, rightclick on the listed audiostream and then select "Interleaving")
Under "Audio skew correction", set an appropriate number of milleseconds (positive or negative) in the box labelled "Delay audio track by"
Save with a new filename

B) If the difference increases as the movie plays:

From under the "Video" dropdown menu, select "Framerate" - and select "Change so video and audio durations match"
Save with a new filename

Let us know of your success ;>}

Thank you setarip_old..........

I use VirtualDubMod 1.5.4.1 (build 2178/release)
the audio lag is present throughout the movie.......

ok...i enter the required time in the 'Delay Audio Track by Box" and clicked ok
then i clicked another "OK" in the "available streams" box........
But nothing seems to be happening.............

can someone please tell me if i m doing it right.....?

Did you then (from the "File" dropdown menu) select "Save as" and save with a new filename?

Thank you very much, setarip_old.........i did just what you had told and the avi now works fine...............i had to repeat the whole process around 25 times before the problem was solved.............

:thanks:

You shouldn't have needed to use trial and error to find the correct delay value...unless you've fiddled with the start of the audio or video streams. You could have extracted the value from the dvd, e.g. by using DGIndex to save the audio and then looking at the delay value in the filename. Much less frustrating than manual resyncing :)
