unsync video

[Shaorin]

I used MKVextractGui to extract the mkv file and then i used avc2avi to convert the h264 file to avi then i used virtualdub to convert it to xvid. Now the video is unsync the audio & subtitle are synced. What why is the video unsync? i checked the framerate and it's the same as the original 29.97 what is wrong?

I also tried using SUPER but it still came out unsync

I would first try convert with alltoavi.

WHat kind of sync problem is it? does it go worse or same the entire clip? If it's same you can fix it pretty easy unsing virtualdub, see https://forum.videohelp.com/topic309224.html#1577383
