But, make sure you dont switch the full range vs normal range in the middle of a project, because it influence how you “see” the image on your timeline.
If you want to read 64-940 on your internal scoop, simply add a soft clip lut set to 64-940 on the timeline track. But then, make sure its set to full range for not doubling the effect.
For the Avid workflow…
Resolve works as it should, just render to YUV and the scaling are correct, no matter if you work 0-1023.
The problem is with Avid. Mediacomposer is not a finishing tool, and there is no way to have Avid to read the files correctly when imported back the regular way or with AMA.
Even though the YUV files from Resolve is scaled to legal, Avid will wash out the black levels and increase the highlights. Its just the way it works. The new major Avid-upgrade that is soon comming has not taken this seriosly, so if you want it to look the same in Avid as in Resolve – there is no way as it is today.
