Kevin,
I suffer from this same problem and it drives me crazy. My work around has been to split the sequence into smaller exports. I usually export two hours movies, so I will split the video into two one hour sections, then export and compress each shorter sequence, and then combine the video afterwards in my DVD/Blu-Ray programs(StudioPro or Encore CS4).
If anyone has a better solution to this problem I am all ears, this work around is still a giant time consumer. Also, I unfortunately don’t have the storage capacity to work in Apple ProRes, so that is out of the question. I also run through the same workflow as Kevin has stated above.
Any ideas on getting a clean export without pixelation?
Thanks
Stephen
