I need some feedback and perhaps a little education about video rendering. I've been editing in Vegas Pro, but I always find that my resulting avi's are enormous. I normally make 3 minute videos, but the file size can sometimes top 2GB. When I try messing around with the settings, I can drop the file size but only at the obvious cost of video quality. This doesn't make sense to me since I have watched hour long videos with better quality than my own for a fraction of the hard drive space.
What can I do to bring my video sizes down to a manageable size without sacrificing so much quality?
