Audio off when i split avi

[joesphroth]

I'm using virtualdub to spit an avi but the second part the audio is out of sync. I've tryed interleaving and cut from a different spot but the audio is exactly one keyframe ahead

Did VirtualDub warn you that the audio was VBR MP3?

If so, easiest way would be to demux the audio then remux it in and cut..

Could you list the technical details of the source from the File.. File information screen?

It is VBR So i tryed it with nan dub and it did the same thing here are specs didn't feel like typeing them

How do i demux an avi with Nandub?

It does not matter, in this case, whether or not you use Nandub -- VBR MP3 can't be cut accurately in an AVI (nor can it be sync'd 100% correctly; that is why it is bad to use in an AVI. VirtualDub's author has a rant on his site about this..).

Open up the file in Virtualdub, and click OK in the warning dialog. Select the Audio menu, and ensure "Full processing mode", "Source audio", and "Compression... No Compression (PCM)" are selected.

Click File... Save WAV and save it with an appropriate name.

Now, click the audio menu again and pick "WAV Audio". Select the file. Then, select "Direct Stream Copy" if you are not planning on doing any audio editing. Also, ensure that "Direct Stream Copy" is selected for the video.

Make your cut; the audio SHOULD be in sync. Good luck.
