The framserving thing is certainly intriquing, what an excellent tool to have in our bag of tricks.

Just to update everyone who's been so helpful, the save as AAF function works well with Premiere I think. Not sure that transitions transfer too well (I think they all convert to dissolves) but otherwise seems okay. I'm doing a test Blu-ray render that's in it's 6th hour. I should have just used a small clip, but oh well.

I'll probably need to brush up on Premiere. It's like driving a stick vs the automatic transmission of Vegas, but each prgram has its strngths.
