Converting WMV to AVI...

Postby Indigo Rose » Mon May 28, 2007 4:56 am

Now, I'm the first to admit I'm an utter ignoramus when it comes to video formats and the like, thus my problem:

I need to convert a WMV into an AVI meeting the following criteria:

- Videos should be in AVI format, compressed using any one of the following: Huffyuv, Lagarith, DIVX or XVID codecs. Videos compressed with DIVX or XVID should be encoded at constant quantizer 2 or 1. Do NOT use special features like B-frames or GMC.
- Audio must be stored as UNCOMPRESSED.

Without noticable loss of quality and, if possible, without getting a filesize larger than a small moon. Any help would be much appreciated.

This is not an option for the following reasons:

1. It is only available in 720 x 576 format, which is a format I do not want and it seems unecessary to change the format back and forth...

2. It somehow messes up both the timing and the audio playback of my video.

Thus, I'd still like an answer to my original question.

You can use VirtualDub(Mod) and AviSynth to do this. Load the WMV via AviSynth's DirectShowSource() function into VirtualDub(Mod). Then File > Save As..., change your Compression: at the bottom to whatever codec you prefer (you can leave Video mode: at Fast recompress). Enter a file name (change the destination directory if needed), leaving Save as type: as Audio-Video Interleave (*.avi) and click Save.

Seems to work pretty well. Thanks a bunch. ^_^

Just to expand my tiny little knowledge: What is a constant quantizer?

technically if you want it uncompressed usually you just leave it as is... or you can right click on that listing on the top and choose "full processing mode" then right click again and choose "compression" and i believe that uncompressed is on there...

if you want to replace that file with another one disable it and add a new file

I also would like to say thanks. I just recently ran into a similar problem as Indigo Rose and, with the help of this thread, got it fixed. No further problems, just thought id say thanks.

You could also do this with GraphEdit without having to recompress. Pipe the output of the WMV parser into an AVI writer and you should be good to go.

avisynth works as a scripting interface... you don't open it, you write a scipt in notepad and save the fale as file.avs.

This is the script I have for AviSynth: DirectShowSource("C:\Documents and Settings\HP_Administrator\My Documents\AMV Folder\Abridged1.wmv") and when I try to open it w/ Virtual Dub Mod I get this error message:

AviSynth open failure:
DirectShowSource: Could not open as video or audio.

Video returned: " DirectShowSource: couldnt open file C:\Documents and Settings\HP_Administrator\My Documents\AMV Folder\Abridged1.wmv: Anobject or name was not found."

Audio returned: " DirectShowSource: couldnt open file C:\Documents and Settings\HP_Administrator\My Documents\AMV Folder\Abridged1.wmv: Anobject or name was not found."

(C:\Documents and Settings\HP_Administrator\My Documents\AMV Folder\Abridged1.avs, line 1)


When I tried change my script to: DirectShowSource("C:\Documents and Settings\HP_Administrator\My Documents\AMV Folder\Abridged1.avs") and I would try to open it w/ Virtual Dub Mod, Virtual Dub would just close.
