What about using a clean HDMI out like the Atomos Ninja2 ? With direct compression to ProRes, does the ISO mulitple still benefit from the '160 rule' as much?
And as far as pushing the blacks up / down, can you be a little more specific for the beginners in the audience. If my workflow is MD3 clean video out to atomos ninja2 (with aforementioned ProRes direct compression), and editing in Final Cut or Premiere, what 'other' post-production software / plugin's etc do you recommend? I'm just learning video editing, have access to the Creative Cloud package, but intimidated by the post-production / color grading, etc that is so often needed.
