The card does not offer any real time down conversion, nor does premiere have any offline capabilities.
As far as using DV then upconverting manually, I’ll have to think about how that would work so let me get back to you.
The problem is whether you’ll be able to sync the timecode correctly cause if 00;00;00 is 00:00:01 you’ve got trouble.
Give me some time to figure this out in my head. lol
