GPU-Accelerated Dolby Vision™ CMU Built-In (Studio Only)
DaVinci Resolve 15 introduced a GPU-accelerated software version of the Dolby Vision CMU
(Content Mapping Unit) for doing Dolby Vision grading and finishing workflows right in
DaVinci Resolve. Previously available only via external hardware, CMU support is now built into
DaVinci Resolve and can be enabled and set up in the Color Management panel of the Project
Settings by turning on the Enable Dolby Vision checkbox. This is a DaVinci Resolve Studio-
only feature.
Dolby Vision settings in the Color Management panel of the Project Settings
The Dolby Vision group of settings also exposes menus for choosing the version of Dolby
Vision you want to use, what kind of Master Display you’re using, and whether or not to use an
External CMU (assuming you possess the option). Finally, turning Dolby Vision on also enables
the Dolby Vision palette and controls in the Color page, which are described in greater detail
later in this chapter.
To master with Dolby Vision in DaVinci Resolve using the built-in software CMU, you still need a
more specific hardware setup than the average grading and finishing workstation, consisting of
the following equipment:
Your DaVinci Resolve grading workstation, outputting via either a DeckLink 8K,
DeckLink 4K Extreme 12G, or an UltraStudio 4K Extreme video interface
A mastering display capable of outputting Dolby Vision levels suitable for the
deliverable you’re required to produce
Simultaneous Master and Target
Display Output for Dolby Vision
When mastering HDR and trimming versions for more limited displays, it’s extremely useful to
be able to evaluate your HDR grade and SDR trim pass side by side. Starting in DaVinci Resolve
15, it’s possible to output both the Master Display output and the Target Display output
simultaneously when you’re grading with either Dolby Vision or HDR10+ enabled.
Necessary Hardware
To work in this manner, you must have the following equipment:
Your DaVinci Resolve grading workstation must output via a DeckLink 8K, DeckLink 4K
Extreme 12G, UltraStudio 4K Extreme video interface, or better.
Your Mastering Display must be capable of Dolby Vision levels suitable for the
deliverable you’re required to produce.
A display that can be set to output calibrated SDR, probably using the Rec. 709 gamut.
