How do I keep audio insync when changing framerate?

[videocheez]

I have a funny AVI clip that i want to eventually use as the opening scene on a few dvd's that I plan to encode next week. I found out that in order to merge AVI's, the two file must have the same framerate and the same resolution. I used vdubs resizing filter to match the resolutions of my small avi clip and my main movie; that was easy. The problem that i am having occurs during framerate conversion. The audio and video go out of sync when i convert the framerate of my little clip from 29.97fps to 23.976fps. The audio is approximately 875ms ahead of the video. I would like to know if anyone has a suggestion as to how i can get the audio and video of my small clip back into sync after framerate conversion.

Thanks in advance,

First extract the audio to WAV with virtualdub...then use virtualdub to change the framerate of the video ONLY (select No audio under the audio tab). Then use Goldwave's time warp feature to stretch the audio to the same length as the new video...should work fine.

Thanks for the tip. Is goldwave freeware or shareware or payware?

Goldwave is shareware...I believe you get a 30 day trial, but it is a fully functional trial.
