What is your preview setting? Did you use an external properly calibrated monitor to judge quality? Your screenshot looks like a display of interlaced material on a progressive monitor.
What are your project settings, source material, codec used and export settings on what OS?
You're a genius!
My Premiere project was set to “Lower Field First” … I was setting the output as Progressive, but the original project was interlaced.
If you used lower field first, chances are you used DV material as a source. Outputting to progressive from PR is a bad idea, since you throw away half the vertical resolution in PR. Just search around for an alternative approach by Dan Isaacs, who has a far better approach to create progressive material for interlaced source. Look for "HD2DV" and similar topics in the CS3 forum and you will find long threads with lots of useful information. If this answers your question, please indicate the topic as ANSWERED.
