Converting WMV to AVI...

Indigo Rose · Post by **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?

Also, about the uncompressed audoi thing... I don't see it mentioned anywhere...

audio can be changed, exported, disabled, compressed in the "streams" menu... under "streams list" in Virtualdub Mod

This is what I get when I open streams list. What do I do from there?

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

Thanks for your help, everyone. I've managed to fix things the way I wanted them. You have my gratitude, such as it is. ^_^
