yes, smpte170m

In vapoursynth, the matrix_in_s="170m", matrix_s="709" arguments were for when you were upscaling the dimensions. It's similar to using colormatrix for 601->709 . But since you decided to change strategy, it's no longer required . However, when you export for a HD targets, you still need to take care of that (if the programs you are using do not take care of it automatically)

And I question the use of 422 , it will just make the filesize larger. Resolve will handle 420 AVC fine, unless there is some special way resolve handles 422 preferably to 420, from a 411 DV source ? Maybe on the BM forum that I don't know about ? (420 still exceeds the 411 source chroma - it's technically upscaled chroma)

422 has benefits in some programs for handing interlace, but you're QTGMCing it here
