A/V sync problem: this is spooky

[LordDethstar]

I'm having a problem: I have two versions of a video clip which all contain errors in different places. That's why I'm trying to create a good version by combining the good parts of each file. I'm making sure that I don't change the framerate and that I cut at the keyframe boundies (although this problem also appears whith codect like Huffyuv). Even though there should be no problems the audio still gets out of sync after a few minutes. Is there any way to solve that problem?

Hi-

You could try saving the soundtrack with the Save WAV command before you start and then mux it back in when done (but, like you, I don't see any reason for it to get asynch in the first place). Also, check the video length when done against one of the original videos to make sure they're both exactly the same length. For that matter, make sure the 2 originals are exactly the same length.
