I have some AVIs with 4CC WMV3, though I can play it normally with media player, still I can’t open it using VirtualDub, I get the error message
“Couldn’t locate decompressor for format `WMV3` (unknown)
VirtualDub requires a videro for Windows (VFW) compatible codec to decompress video. DirectShow codecs, such as those used by Windows Media Player, are not suitable."
Any help where I can find that WMV3 codec please.... reply

See steps 8 or 9. If you’ve already got these then those AVIs may not infact be AVIs, they could just have an .AVI extension.

Try opening them in The Faimous One’s Codec Finder:

Note: The Faimous One’s Codec Finder will *only* read *true* AVI files.

WMV3 content is usually encoded to .WMV. If this is the case, then VirtualDub won’t be able to work with it. Alternatively, you *could* try VirtualDubMod, maybe it will give better results. reply

thanks for your reply but I already found the codec now in microsoft site. I beleive it is a new codec and this is why it is not so popular. The vids are real ACI’s coded using ths code and after installing it, VirtualDub is working fine with it. Anyway, the link for this codec if anyone interested to try is

Opps, lol. I forgot to put the links to steps 8 and 9.

For anyone else. Read this:
http://forums.afterdawn.com/thread_view.cfm/48608

And scroll down to steps 8 & 9. These steps are virtually the same as Alex posted. The steps also detail which version of the codec package to install for your given version of Windows Media Player.

While you can put WMV9-WMV3 stuff in an .AVI container, it’s actually natively supported in a .WMV container.

WMV3 itself is just an updated version of Microsoft’s MPEG4 codec variant and so this is why the codecs on the system need to be updated. Last time I used WMV3 (FourCC for Windows Media Video 9 encoded stuff) was about 3 or 4 months ago. Did a bit of encoding too.

Incidently, you can also encode to WMV9 using TMPGEnc.

What are you doing with the WMV3 files, Alex? Are you re-encoding them or something else? reply

Actually I’m joining them together, I got some movies that is splited in parts and I would like to join it together in 1 big file. When I tried to join it using Easy video joiner and similar programs it cause some problems like no sound in some parts of the movie so I had to re-encode them using VirtualDub which was the only solution for me to join it correcty !:)
The point is that I read step 8 and 9 which you mentioned and followed it but it didn’t help, I guess it these codecs are usefull to view the movies but not for re-encoding it.. what do you think ?

This is off-topic for this thread (it deals with WMV3 and your post deals with DX50). Anyway here’s steps for your problem.
1. Get the divx play bundle from www.divx.com (DX50 is the fourcc for DivX 5)
2. Open your file in VirtualDub, click video, pick 'Direct Stream Copy'. (Very important)
3. Click Audio, pick no audio (if the video frame rate is slower, the audio length won’t match)
4. Click video, frame rate. Click on the second box 'change frame rate to ___ frames per second' and type in the number you want.
5. Click file, save as avi. Type in a name and you’re done. reply
