No video in my AVI files

I use MPEG because I have a Sony IP220 and if I render my Micro MV files as *avi files V3 finds the audio in the tracks but doesn't see any video. The files work perfectly in other media players eg Windows Media Player. Any idea?
Thanks,

Try the free-trial codecs from Mainconcept and/or Morgan... hope this helps.
Your camera, is it a video or a still cam that does video files?

Thanks for the suggestion but the only codec I can find is avi to mpeg, which is the opposite direction to the one I need. I have mpegs that I need to save as avi's. Movieshaker does this but Vegas doesnt' see any pictures in them, it only sees the audio track. The avi files play fine in Windows Media Player though. It's a bit frustrating.

I'm making a few guesses here...

The only avi files I haven't been able to get into VV are ones with some sort of problem or idiosyncracy in the codec. I have had some success with software using problem codecs (ie: Matrox dmb1 I think a few years back) by changing the header of the avi file itself. You need to have another, similar codec (as in both mpeg1) on your system, and use something like avi.exe to set the flag in the header so that software thinks it is the other codec and uses the other decoder. An alternative would be to set your system to use the other codec in the first place (Matrox folks used to do this) by associating the other codec with the indentifier for the problem one. (depending on your OS, could be as simple as one line in the system.ini file)

There are a few tools available at places like digital-digest.com that would let you look at or change the file headers - can't say what will work - but that would be preferable to the quality loss you'd get rerendering the file to another codec.

Other alternatives you might get to work would be something likie VFAPI or avisynth which act as a bridge more or less between the avi and the software. I'm far from expert with either, but generally if media player can play it, avisynth will handle it.

One solution I found for this problem:
-I have a Canon G2 still camera that does MVI.AVI files and with these video files I record I got the exact same problem and limitations you got. Sound and no picture but A-1 in Quicktime and WinMedia players...
-I got a FREE solution for you now: I downloaded CamStudio 1.8, wich is an application that allows you to record what's on your screen in .avi files that CAN be imported in Vegas. The trick: there's the possibility to avoid recording the whole screen by selecting a framing option; you draw a square (rectangle) around the player's screen and that's it, you record your file.

You can get CamStudio for free there: http://www.rendersoftware.com/products/camstudio/index.htm

Good luck!

Thanks for the help guys. I will give your suggestions a try. What an amazing workaround though. I would have thought that SoFo would have this sorted out????
