Unofficial VirtualDub Support Forums > Advanced Video Processing > Avi Audio Out Of Sync

(Sorry if this should be in the noobie section - wasn't sure!)

Hi All

Basically, I'm having a problem joining (using the append option in virtualdub) 2 AVI's together. They are both exactly the same in terms of frame rate, audio, size, codec, etc, and they do join together,

BUT

In the second half of the joined file, the audio is out of synch with the video

. The first half is fine, and on the two separate files the audio is fine in both sections.

I have been using the 'direct stream copy' for both audio and video, as thats what i want, a nice quick way to join a bunch of avi clips.

Any help would be much appreciated, as im a bit confused

, thanks in advance, laters

What's the video source. DVD? Perhaps you need to account for a delay.

Thanks fcchandler, that other thread is the exact problem i'm having!

Neo Neko - I think the original source may have been DVD, but I only have the separate avi files, and each of them on their own is just fine, completely in synch audio all the way through, it just gets screwed up when i try to join the separate parts!

I'm gonna give avisynth a go, but never used it before, and seems quite daunting! Thanks
