I am not sure if this belongs here, but I have not seen it addressed anywhere else. I have a video clip in .avi format which plays just fine using Windows media player. I tried to convert it to dvd format to burn, and the audio is suddenly longer than the video. It is NOT offset, it is longer. I tried decompressing the audio with the same results. I tried splitting the audio off into a .wav file, but it is several seconds longer than the video. I have absolutely no idea why this is happening. As I said, the .avi file plays fine with no audio problems.

Does anyone have any idea why this happens and what I can do about it?

Well with the information you give I could only guess it's because the original AVI has VBR audio, but hard to tell as you haven't told us what programs you used to try to convert it to DVD and the program used to decompress the audio......

If you used VirtualDub/VirtualDubMod, did you get a VBR audio warning when you opened up the file?

I use Virtual Dub and there is no indication that it is VBR - no warning at least. I used video filters to brighten the clip, then processed the resulting .avi file through DVDSanta to get the format. That's when I noticed the audio problem. I then tried Vegas and DVD Architect and saw that the audio was longer than the video. Splitting off the audio with Virtual Dub also gave an audio .wav file that is longer than the video. I am stumped. Thanks for any suggestions.

Hi!

What video and audio codecs did you use when you created the original .AVI?

1) Load the original video file into VirtualDub (or one of its many variants) or NanDub

2) From the "File" dropdown menu, select "File Information"

3) Post (here) EVERYTHING you see (BOTH video and audio information), or post a screen capture .jpg of the information box

Thanks to all who helped. I finally arrived at a solution. It doesn't explain why the audio was too long, but it worked. I took my extracted .wav file, used SoundForge time stretcher, input the lingth of the video, and got a .mp3 file that was just the right size. No problem after that. I put the 2 files together, rendered an .mpg file and everything was fine.

Thanks again, guys.
