User Manual

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.
Enabling Simultaneous Monitoring
When you set up your display hardware, the HDR Master Display must be connected to output
A, and the Target Display must be connected to output B of whichever BMD video output
device you’re using. Then, you need to turn on the “Use dual outputs on SDI” checkbox in the
Master Settings of the Project Settings. At this point, assuming all of your connections are
compatible with one another, you should see an HDR image output to your HDR display and a
trimmed image output to your SDR display.
Limitations
As of the time of this writing, there are some limitations to simultaneous HDR/SDR output from
DaVinci Resolve.
 The resolution for both the Master and Target output is limited to 1080; choosing a
higher resolution may cause problems.
 This workflow does not work for Stereo 3D projects.
 Each output is limited to Single Link (a single HD-SDI connection).
 Output can be either 444 or 422.
HDR10+ Auto Analysis Commands
After you’ve graded an HDR version of each clip in your program, a set of HDR10+ specific
commands let you auto-analyze each clip to create custom HDR to SDR downconversion
metadata that give you a starting point for the SDR trim pass you need to do. These commands
are available in the Color > HDR10+ submenu:
 Analyze All Shots: Automatically analyzes each clip in the Timeline and stores the
results individually.
 Analyze Selected Shot(s): Only analyzes selected shots in the Timeline.
 Analyze Selected and Blend: Analyzed multiple selected shots and averages the
result, which is saved to each clip. Useful to save time when analyzing multiple clips
that have identical content.
 Analyze Current Frame: A fast way to analyze clips where a single frame is
representative of the entire shot.
HDR10+ Palette
An HDR trim palette is available to all Resolve Studio users, which provides controls for
manually trimming the auto-analyzed trim metadata. At the time of this writing, nine sliders
control the bezier handles and control points of a custom curve that can be used to shape the
luminance mapping curve, including Knee X and Y sliders. These sliders are disabled until you
analyze the current clip using one of the commands described above, at which point they
become enabled for trimming.
