Non standard PAL frame rate...

[vasudev71]

Hi,

I have a bunch of ASF files which I converted to AVI using VirtualDub 1.4c (Direct stream copy). When I checked the file information on both the ASF and AVI file, I was shocked to see the framerate listed is not a fixed 25 fps (PAL) but instead is varying for each file. (25.112, 25.125, 25.128...etc). I tried to use the PAL template found in TMPGEnc but that doesn't help. The video/audio goes out of sync when the resulting MPG file is being played. The surprising thing is the AVI plays in perfect sync when played thru Media Player/VirtualDub 1.4.10. Guessing how?

I really need to fix this (either I should go for NTSC VCD or PAL VCD). I would appreciate if any expert gives me a very good solution on this. No matter what the framerate is, I should bring it down to 25 fps (PAL) or 29.97 (NTSC).
This should also take care of the audio/video sync.

Please help me out.

Thanks in advance.

It looks that it is captured, and therefore such framerate... Anyway, only way what I see is that you perform timestretch on audio by factor Framerate of AVI/25 . Then load this audio in Virtual Dub and By Framerat check Change so audio and video duratiom match.
You should then get 25 fps.

Other way us to force framerate to 25 with AVISynth, but it will cause choppiness.

You can use AssumeFPS in Avisynth, there the audio (!) is stretched.
