Richard and Andrew,
thank you so much for the useful info and the piece of mind to know that its something that can be manageable.
I have a lot of stuff I shot on the fly as well too, that I will be using Plural Eyes 3 to Sync up, since it will take a very long time if i did it manually. if I sync it up using Pluraleyes (still at 44.1) and then pull it into premiere, then when I have a cut i am satisfied with i could always export it at 48k. is that possible? or something will go wrong, hypothetically if it looks all synced up.
thanks again
