Authorizing DaVinci Resolve to Expose
Advanced Dolby Vision Controls
To expose the Dolby Vision controls in DaVinci Resolve Studio that let you make manual trims
on top of the automatic analysis that any copy of DaVinci Resolve Studio can do, you must email
[e-mail] to receive more information about obtaining a license.
Once you’ve obtained a license file from Dolby, you can import it by choosing File > Dolby
Vision > Load License, and its successful installation will enable the Dolby Vision controls to be
enabled in the Color page. You should also receive a configuration file, which can be loaded via
the File > Dolby Vision > Load Configuration command, which lets you populate the Dolby
Vision drop-down menus with the most up to date options.
Dolby Vision Trim Controls in DaVinci Resolve
Once you’ve analyzed a clip, you’re in a position to trim the result. The latest version of the
Dolby Vision palette exposes four sets of controls. The first are the main controls:
 Target Display Output: This menu lets you choose the levels at which you want to view
the trimmed downconversion, to obtain a preview of what the trimmed image will look
like on different displays with different peak luminance capabilities.
 Trim Controls for: For writing the XML. This drop-down, which defaults to “100-nit,
BT.709, BT.1886, Full,” specifies what Dolby refers to as the Target Display used to
display the trimmed downconversion, which at this default setting lets you monitor
an SDR version of the HDR image so you can see how the Artistic trim metadata
downconverts the image on non-HDR televisions. Without a license, this is locked to
the default. With a license, you can choose from a variety of different options.
 Analyze controls: The commands governing Dolby Vision auto-analysis are available
as buttons, which perform the same functions as their similarly named counterparts in
the Color > Dolby Vision™ submenu. Please note that most trim controls are disabled
until you perform an analysis, which is a necessary first step.
–
All: Automatically analyzes each clip in the current Timeline and stores the results
individually.
–
Selected: Only analyzes selected shots in the Timeline.
–
Blend: Analyzes multiple selected shots and averages the result, which is saved to
each clip. Useful to save time when analyzing multiple clips with identical content.
–
Frame: A fast way to analyze clips where a single frame is representative of the
entire shot.
 Enable Tone Mapping Preview: Lets you see the target display output in the Color
page Viewer and video output, so you can evaluate how the downconverted version
looks on your HDR display. This control is disabled when you enable “Use dual-outputs
on SDI” in the Master Settings of the Project Settings, since the second output SDI now
automatically displays the target display output.
 Mid Tone Offset: This is an offset to the computed tone mapping target average light
level (according to Dolby’s documents).
The second are the metadata fields that are populated by the analyzed values of the current
clip. Once populated, these fields cannot be edited. This data is used to calculate how the HDR
image should be trimmed to fit into the video standard specified by the Target Display:
 Min: The minimum PQ-encoded pixel value, aka minimum picture level, the darkest
pixel in the image.
