outputting 800 nits worth of signal and clipping any image details from 801–1000 nits because
there weren’t that many details above 800anyway. Or, if you’re gradinglarge explosive fireballs
up above 800 nits in their entirety because it looks cool, then maybe the audience will notice.
The bottom line is, when you’re grading for displays that are only capable of ST.2084, you need
to think about these sorts of things.
Monitoring and Grading to ST.2084 in DaVinci Resolve
Monitoring an ST.2084 image is as simple as obtaining a ST.2084-compatible HDR display and
connecting it to the output of your DeckLink 8K, DeckLink 4K Extreme 12G, or UltraStudio
4K Extreme.
Setting up Resolve Color Management to gradefor ST.2084 is identical to setting up tograde
for Dolby Vision. You’ll also monitor the video scopes identically, and output a master
identically, given that both standards rely uponthe same PQ curve.
TIP: If you’re monitoring with the built-in video scopes in DaVinci Resolve, you can turn
on the “Enable HDR Scopes for ST.2084” checkbox in the Color panel of the User
Preferences, which will replace the 10-bit scale of the video scopes with a scale based
on nit values (cd/m
2
) instead.
Connecting to HDR-Capable Displays using HDMI 2.0a
If you have a DeckLink 4K Extreme 12G or an UltraStudio 4K Extreme video interface, then
DaVinci Resolve 12.5 and above can output the metadata necessary to correctly display HDR
video signals to display devices using HDMI 2.0a when you turn on the “Enable HDR metadata
over HDMI” checkbox in the Master Settings panel of the Project Settings.
The Enable HDR metadata over HDMI option in the Master Settings
panel of the Project Settings lets you output HDR via HDMI 2.0a
When you do so, a setting in the Color Management panel of the Project Settings, “HDR
mastering is for X” lets you specify the output, in nits, to be inserted as metadata into the HDMI
stream being output, so that the display you’re connecting to correctly interprets it. The output
you specify should match what your display is expecting.
The “HDR mastering is for” setting lets you insert
metadata for HDR output via HDMI 2.0a
