While this table of values is useful for understanding where HDR nit levels fall on legacy external

scopes, 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

replaces the 10-bit scale of the video scopes with a scale based on nit values (or cd/m

) instead.

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 HDR for enhancing the consumer video experience,

Dolby Laboratories 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 PQ (perceptual quantizer)

electrical-optical transfer function (EOTF, which defines how an electronic video signal is presented on

a display), which is defined by SMPTE ST.2084, along with a hierarchy of metadata that’s embedded

alongside the video stream. All metadata used by Dolby Vision is organized into levels, of which the

following are important to the colorist:

– Level 0 metadata, which is global metadata that defines the Mastering Display (what the colorist is

using), including aspect ratio, frame rate, color encoding and information on all the target displays

that are used for the Level 2 and Level 8 trim metadata below.

– Level 1 metadata, which is the Dolby Vision v2.9 analysis metadata that’s generated automatically

when you use the Dolby Vision controls to analyze the clips in the timeline. The controls for

automatically generating Level 1 metadata are available to all DaVinci Resolve Studio users.
