Ok ive been trying to figure this out my self and i downloaded another version of VirtualDubMod. This time i can click compress and everything but when i try to open my .avi files it comes up with an error saying "Couldnt locate decompressor for XviD" and some other craps..

"Couldnt locate decompressor for XviD"

That means you don't have XviD installed.

To "uncompress" a video, open it in VDM, go to the Video tab and select "Normal Recompress". File>Save As. Look at "Compressor" on the bvottom of the window and see if it says "Uncompressed RGB". Note that this does not improve the quality of your video, but just makes it bigger.

To compress, do the same thing but select your desired codec instead of "Uncompressed RGB".

IMPORTANT: You should learn how to configure a codec before just going at it with the default settings, because default settings usually suck. For lossless compression, default is fine. For XviD, look here. For other lossy codecs (DivX, x264, etc) google a guide.

Note that this does not improve the quality of your video, but just makes it bigger.

Knowing WHY you want to do something is a pretty big help. As mentioned, if you start with a crappy quality video and save it as an uncompressed rgb, Huffyuv, lagarith, or any other lossless type format you'll have a very large, crappy video. There may be times when this is what you want, or if your footage is of very high quality, such as an HD capture that it won't matter.

Read the entire guide from the beginning, not just the Xvid section posted in Gepetto's post, and learn the techniques. Knowing what you're doing will not only help you, but will help you to frame your questions in a way that you'll get a real answer.
