Grading LUT

Grading LUT operator properties for Script Engine. Applies a pre-baked colour grade defined by a 4096×4096 24-bit RGB PNG look-up table image. Useful for matching a project to a shared house style, applying a film-emulation look, quickly switching between graded and ungraded versions of a feed, deploying the same grade across many compositions, or trying out third-party LUTs from a colourist. The Dry/Wet slider lets you blend the LUT effect with the original image.

Property Type Access Description
LutUrl Uri get/set Path to the LUT image file. The file must be a 4096×4096, 24-bit RGB PNG. Set to a valid file path/URL to apply the grade. Files are searched relative to the project's media folder if a relative path is given. Loading failures are reported in the status AssetLoadingMessage.
Amount int get/set Blend amount between the original image (dry) and the LUT-graded image (wet), in percent. [min=0, max=100, default=100]. 0 shows the unmodified source. 100 shows the fully graded image. Use intermediate values to soften the strength of an aggressive grade, or animate this value to fade a LUT in and out smoothly during a transition.
AssetLoadingMessage FormattedMessage get Latest LUT loading status message with timestamp (read-only). Reports successful loads, missing files, format mismatches, and other errors.
