I see, thanks. Not being an engineer I'm going to give you my interpretation of your answer. So, please bear with me for a moment. The 10bit dpx files contain data beyond what is considered 'broadcast safe', so it's 0-1023 vs 64-940. Since the CM171 is a 10bit display it should be able to show 0-1023, but that is not broadcast legal. Deke viewer_input node is converting the 0-1023 'signal' in to the legal 64-940 range. By converting to 'legal' at the viewer_input level you're essentially grading in a WYSIWYG mode, because that is what you will see on the CM171. Otherwise you need to convert the grade done at full rec709 to legal rec709 and I have been told that you can cause the tonality to sometimes shift around etc So, to to summarize: CM171 (10bit rec709) driven via thunderbolt Ultrastudio mini monitor over SDI. 1) Sony F3 footage (uncompressed 10bit RGB 444) de-loged and converted to rec709 with a 3d LUT in resolve. (I will attempt to do this step in nuke7 via OCIO) 2) Read node set to REC709 3) Nuke viewer LUT set to REC709 4) Viewer input node to convert to legal rec709. This converts the output to the CM171 from full to legal 64-940 5) Grade, blur, add grain. Final. Does this sound correct to you? Thank you.
