ASF/WMV conversion in VirtualDub

[Slekvak]

Hi,

I've been trying to convert a ASF/WMV file to XviD/MP3 using VirtualDub. Whatever config I may try, I always end up with audio/video unsynced. Is there another, better method, or am I doing anything wrong? Are there any Tips and/or Tricks?

Thanks

Frameserve the WMV file into VirtualDub with an up-to-date version of Avisynth!
http://sourceforge.net/project/showfiles.php?group_id=57023&package_id=72557&release_id=366702

The following script should do the job:
DirectShowSource("C:\Path to WMV\Foobar.wmv", fps=25, convertfps=true)

The fps and convertfps options are required, as VFR -> CFR conversion is mandatory!
Of course you may have to adjust the framerate to your specific input video...

I did try that, and I got an error when opening the file in VDub. Something along the lines "Timeout waiting for graph". Will try the newest version (if that's not what I have already).

Does your WMV file play in GraphEdit ???

Tried updating AviSynth, and the file seems to open fine in GraphEdit. When opening in VirtualDub (newest), it freezes and after some seconds this error appears:

Avisynth open failure:
DirectShowSource: Could not open as video or audio
Video returned: "DirectShowSource: Timeout waiting for graph to start."
Audio returned: "DirectShowSource: Timeout waiting for graph to start."

You could still try to do the first step of conversion with mencoder:
mencoder.exe -ovc lavc -oac pcm -lavcopts vcodec=ffv1 -ofps 25 -o C:\out.avi "C:\Path to Video\Foobar.wmv"

Then do the further editing in VDub...
