Hi,
I would use all ‘best’ settings in AE. And remember to render LOWER FIELD FIRST.
The ‘banding’ you are getting is because of the 640×480 file you tried.
I really am not sure exactly how long this will take on your machine. You really aren’t adding any filters or anything that is time-consuming. I’d render it overnight….a 90 minute program should finish on your machine overnight….I think!
Remember, export ‘by reference’ from Media100 and bring that reference file into AE. Render at 720×486 lower field first. After rendering, crop your file in BitVice and make your appropriate settings.
Let us know how things went!
Paul
