Help us out here, James. We don’t have enough information to solve your problem.
What is your workflow?
– AE-to-Premiere?
– how are you rendering out of AE? Codec? Frame size? Output module? (try the render queue, not file>export)
– What are your sequence/timeline/codec settings in Premiere?
– What is your final deliverable?
What do you mean when you “produce it and watch it on a TV it looks fine?” What do you mean by “produce”? Do you mean that your AE output looks fine after it’s been through Premiere, then output from Premiere to DV tape?
Throw us a bone, man …
