The size has nothing to do with whether it is avi or wmv. It depends on how much it is compressed. If 5 minutes takes 3GB is sounds like it isn't compressed at all. It is just raw video. What you need to do is encode it. Whether you then put it in a avi or mp4 container won't matter much.
I use MeGUI
for most of my encoding. Here
is a really nice tutorial on using it, although you won't need to do every step as you already have a avi file.
