You can define the color space and gamma when streaming from DaVinci Resolve with a Blackmagic Design DeckLink source, allowing you to stream color-accurate content to any professional monitor or projector. Your viewers can also customize these settings to suit their hardware.
Note
Currently, the only color-accurate workflow is hardware-dependent on Blackmagic and calibrated monitors, and must be run through Stream DeckLink or Stream files.
Other options such as Stream NDI, Screenshare, Stream other devices, and EBS are not guaranteed to represent colors correctly.
Here's how to do it:
Access the color settings from the Stream button on the bottom toolbar (in Conference mode) or from the DaVinci Resolve button in the bottom toolbar (in Stream only mode). More info
Here are the color settings you can customize:
-
Color space dropdown: You can select from predefined pairs of primaries and transfer functions.
If you select Custom in this menu, you can independently select a set of color space primaries.
Note
Primaries define the maximum values for red, green, and blue relative to the visible light spectrum. Examples: Rec.709, Rec.2020, D65.P3.
Transfer function defines how the signal maps to actual luminance values in the display. Gamma functions are one type of transfer function. Examples: Gamma 2.4, PQ, HLG.
-
Primaries dropdown: If you select Custom in the Color space menu, you can independently select a set of color space primaries.
-
Transfer function dropdown: If you select Custom in the Color space menu, you can independently select your transfer function.
-
Video levels dropdown: You can select between Full and Legal levels, as appropriate for your software.
Note
Legal (also called Video or SMPTE range) refers to the color range developed for TV broadcasting. In 8-bit, instead of 0-255 color values, legal range is 16-235. In 10-bit, instead of 0-1023 color values, legal range is 64-940. Color values outside the legal range will be clipped.
- Allow approximate gamma checkbox: With this option checked, Evercast performs fast, high quality color space transformations. If greater precision is required, uncheck this option.
