hi all,

i capture avi from VHS tape and convert them to divx5 ( & mp3 for audio) video file using Virtual Dub. but i always have audio and video sync problem.

I capture audio at 48Khz 16bit stereo, and my encode setting is 48KHz 128kbs CBR mp3 (lame 3.9.1).

When i encode 1 avi file, it sounds fine and auio and picture sync right. But when I join multiple avi files into 1 avi, audio doesn't sync I've tested some other ways that i can think of to solve this problem (encoding at 44.1KHz, using Fraunhofer IIS MPEG Layer-3 Codec...) but so far i havent found the solution.

I was just wondering what everyone is using for their audio encode setting?? or Should I just not use mp3??? (Yesterday I installed Ogg Vorbis audio codec because i hear it is pretty popular.)

please give me ANY advice if you have. (I searched the logs of this forum too but sorry if this is frequently asked questions )

Have u tried handling the video and audio seperately? I don't know if vdub can do it, but try capturing the audio as wav, then joinin the video and audio seperately. Encoding the audio to mp3, then muxing with the avi.

Hmmm intersting problem......... Have you checked that the frame rates on all the segments is the same? I did some searching and found this thread in the Capturing Video Forum.
