The video scopes with “Enable HDR Scopes for ST.2084” enabled
in the Color panel of the User Preferences
TIP: If you’re unsatisfied with the amount of detailyou’re seeing in the 0–519 range
(0–100 nits) of the video scope graphs, then you can use the 3D Scopes Lookup
Tablesetting in the Color Management panel of the Project Settings to assign the
appropriate “HDR X nits to Gamma 2.4 LUT,” with X beingthe peak nit levelof the
HDRdisplay you’re using. This converts the way the scopes are drawn so that
the0–100 nit range of the signal takes up the entire range of the scopes, from
0through 1023. This will pushthe HDR-strength highlights up past the top of the
visible area of the scopes, making them invisible, but it willmake it easier to seedetail
in the midtones of the image.
Dolby Vision™
Long a pioneer and champion of the concept of HDR for enhancing the consumer video
experience, Dolby Labs has developed a method for mastering and delivering HDR called
Dolby Vision. As with most HDR standards discussed in this chapter, Dolby Vision uses the
SMPTE 2084 “PQ” EOTF along with two levels of metadata:
 Analysis metadata (Level 1), which is generated automatically via an analysis of the
image. This automatically generated Level 1 metadata is available to all DaVinci Resolve
Studio users.
 Artistic trim metadata (Level 2), which is set by the colorist via the various trim controls
found in the Dolby Vision palette, allows adjustment of how the Dolby Vision image is
to be mapped to a target display that’s different from the mastering display (such as
a 100 nit Rec. 709 display). The purpose of this metadata is to maintain a program’s
artistic intent by providing guidance from the colorist over how its signal should be fit
into the differing luminance ranges of a variety of displays. Manually adjustable Level 2
metadata is only available via a license from Dolby.
DaVinci Resolve provides access to the SMPTE 2084 PQ EOTF settings required for mastering
Dolby Vision in three different ways: as Color Space and Gamma settings in RCM, as Color
Space and Gamma settings within a series of ResolveFX plug-ins, and as a set of 3D LUTs
created for converting signals from one standard to another. While Dolby Vision content is not
limited to a particular color space, Resolve Color Management provides a P3 D65 setting that
matches the capabilities of most mastering displays in use at the time of this writing.
