I got Sony Vegas a few days ago and had a problem with previewing video and uninstalling all my codecs and then installing K-Lite (Full) fixed it. So I got it working now, i have a 9min 480x360 60mg .avi file i added reverb and upped the contrast on it now when I render it takes so long that i have to cancel it cause it would take 15 hours to render. I got one combination of codecs to render within a hour and then the file that got saved was 3gb. Am I doing something wrong? Cause I hope so. Is there a way to make the process faster and have smaller files?
