LUTCubeAnalyzer

Export requires the specially ordered LUTCubeCreator color target. Pass it through the static processing you intend to transfer. An ordinary MediaIn frame contains only colors present in that scene and cannot replace a full cube image.

Connecting Creator directly to Analyzer creates an identity LUT. This is a useful first check: before building a complex look, verify that the chosen format writes and is read correctly by the target tool. The manual states that Analyzer displays nothing in the Viewer; an empty view does not by itself indicate export failure.

The transferable operation maps input RGB to output RGB. Coordinate masks, blur, grain, flares, tracking and temporal adaptation require information absent from a three-dimensional color table. Even a color tool is suitable only in a mode that does not depend on neighboring pixels or analysis of a particular frame.

Preserve cube-image geometry. Resize, Letterbox, Crop, warping, smoothing filters and lossy storage alter sample placement or values. For a cube processed outside Fusion the guide recommends 32-bit floating point; after reimport, check its dimensions and the absence of an additional color transform.

The archived Inspector shows ALUT3, CUBE and 3DL. The Resolve 21 section uses ITX rather than CUBE in its format list, so verify available labels and compatibility in the installed build and receiving application. Renaming a file extension does not convert its contents.

A Viewer LUT changes display rather than automatically changing the Analyzer branch values. A transform intended for the written LUT must be explicitly applied to the cube image. After Write File, load the file separately through FileLUT and compare it with the original chain under the same Viewer transform; export again after changing the look.
