I have a long form project that is 1080i. At the moment some of the footage is DVCPro, some is DNxHD 145 and some is DNxHD-TR 145.  There are 3 separate sets of stereo track pairs: one is the standard sync audio, one is sync audio plus optional additional V.O., and one is sync audio plus commentary track. I need to output this project to a file that another facility can transfer to HD-Cam SR.

Question 1) Do I need to do a video mixdown or transcode the DVCPro material to DNxHD before outputting the project to a quicktime movie?

Question 2) How can I preserve six discreet tracks audio in this export? (When I try to do this with my audio project settings on Direct Out, I get an error message: "Audio Exports cannot be performed in Direct Out mode because clip-based pan info is not applied..."

Thanks for any help you can provide!
