Output Colorspaces

Livegrade lets you manage looks with an output colorspace attribute for streamlined handling of looks and video signals within multi-monitoring setups and advanced color pipelines.

Assigning an Output Colorspace

You can assign the desired output colorspace in the output colorspace node at the bottom of the grade editor. Livegrade automatically detects the correct output colorspace of built-in LUT presets, ACES ODTs, FilmLight Viewing Colorspaces or Colorfront CFE Out transforms.

For custom LUTs you can assign the correct output colorspace on loading. Once the output colorspace for a custom LUT is defined Livegrade handles the output colorspace for your custom LUT automatically.

On look export, Livegrade adds the output colorspace attribute as a LUT comment


Example for Output Colorspace Tag of a LUT File

In the example shown above, the output colorspace of the LUT is set to P3-D65 PQ.

Other Livegrade systems will then auto-detect the appropriate output colorspace of your custom LUT on selection.

Tag User LUTs with a certain output colorspace

The following table shows you a list of all supported output colorspaces and the corresponding comments to tag a LUT with a certain colorspace.

Colorspace Comment
Rec. 709 # LIVEGRADE_OUTPUTCOLORSPACE rgb/rec709/d65/bt1886
Rec. 2020 # LIVEGRADE_OUTPUTCOLORSPACE rgb/rec2020/d65/rec2020
P3-D65 # LIVEGRADE_OUTPUTCOLORSPACE rgb/p3/d65/gamma26
P3-D60 # LIVEGRADE_OUTPUTCOLORSPACE rgb/p3/d60/gamma26
Rec.2100 PQ # LIVEGRADE_OUTPUTCOLORSPACE rgb/rec2020/d65/pq
Rec.2100 HLG # LIVEGRADE_OUTPUTCOLORSPACE rgb/rec2020/d65/hlg


Handling shots using the Output Colorspace attribute

A look’s output colorspace is stored as shot attribute in the shot library so that you can

  • view and sort the output colorspace column in the shots table,
  • inspect a shot’s output colorspace in the info tab,
  • or include it in reports.

Furthermore, you can filter your shot library using the output colorspace smart group (e.g., when applying looks for HDR/SDR dual monitoring setups).

Output Colorspace Smart Groups

For further communicating the output colorspace attribute, you can use the output colorspace token within the wildcards for the Clip Identifier, in the file naming scheme for  saving shots and for the still image export.

Tag Still Images with a Color Profile depending on Output Colorspace

You can enable the color profile tagging for still images within the “Advanced” preferences. Livegrade then tags still images with an appropriate color profile for most common output colorspaces (Rec.709/Rec.2020/Rec.2100 PQ/Rec.2100 HLG/sRGB) on export. The image tagging applies to still images exported from the viewer window as well as when saving shots from the shot library.

Auto-configure Video Scopes depending on Output Colorspace

The correct color primaries value for video scopes can be detected automatically depending on the current look’s output colorspace so that the video scopes are always configured appropriately for the currently selected slot (e.g., when working with HDR/SDR dual monitoring setups).
