LUT Cube Analyzer Node

The LUT Cube Analyzer takes an image originated by the LUT Cube Creator as an input and allows the user to create a 3D LUT file in ALUT3, ITX, or 3DL format.

Feeding the original LUT Cube Creator image into the node results in an unaltered, or 1:1, LUT file, and nothing is displayed in the viewer.

You can, however, modify, grade, and color correct the original cube image with as many nodes as you like and feed the result into the LUT Cube Analyzer. This creates a LUT that exactly resembles your color pipeline.

LUT Cube Analyzer Node Inputs

The LUT Cube Analyzer includes a single orange input.

  • Input: The orange input is used to take the output of any node modifying an image that originated with the LUT Cube Creator.

LUT Cube Analyzer Node Setup

The example below shows a node tree starting with a LUT Cube Creator node and going through two color adjustments. The adjusted image is then connected to a LUT Cube Analyzer, which generates the LUT file.

LUT Cube Analyzer Node Controls Tab

The Controls tab for the LUT Cube Analyzer node is used to select the desired LUT output format, specify a filename, and write the 3D LUT to disk

Type
Select the desired output format of the 3D LUT.

Filename
Enter the path where you want the file saved and enter the name of the LUT file. Alternatively, you can click the Browse button to open a file browser to select the location and filename.

Write File
Press this button to generate the 3D LUT file based on the settings above.

LUT Cube Analyzer Node Settings Tab

The Settings tab in the Inspector is also duplicated in other LUT nodes. These common controls are described in detail HERE
