can't give you answers you need. but nutshell: datarate determines quality (and final file size). H.264 is *very* good at high quality at low data rates. So yep, something not workingn for you. I don't use Premiere, and am on OS X, the quickest but not painless solution is to cough for QT pro from Apple, export in an uncompressed format from premiere then recompress via QT pro. In terms of settings, this depends on what Premiere gives you access to, but you should be able to: set frame rate data rate frame size keyframe rate (despite some other advice here I believe automatic or natural is much better than forcing key frames) dual or single pass. The really important ones are keyframes and double pass, if the codec you are using is only doing single pass then it will be short of being optimised. hope some of this helps, and Michael and Ryanne's tutorials at freevlog I think cover these settings pretty well. -- cheers Adrian Miles this email is bloggable [ ] ask first [ ] private [x] vogmae.net.au [official compliance stuff:] CRICOS provider code: 00122A
