Thanks guys,
OK, at least its normal. I was sure 18 gigs for 4 minutes was insane. I needed to output to youtube. i just rendered out to 720p and a lower DNxHD bit codec. i got it to only 2 gig. And joe, thatnks for mentioning Open GL and Looks not playing nice. I was wondering what all that was about in AE. I kept getting errors.
Both of you guys have been a great help. Creative Cow is great!
Marc
