About

LUT Generator is a browser-based workflow for using a visual reference as the starting point for a reusable color look. It works with photos and normalized SDR video frames, with color refinements and optional AI suggestions.

Features

Match a source image or SDR frame to a reference direction.
Fine-tune the appearance and keep a PNG preview for comparison.
Export a custom .cube LUT for compatible editing workflows.
Choose sRGB for photos or Rec.709 Gamma 2.4 for normalized SDR footage, matching the editor settings to the export.

Use cases

Creators can explore a consistent palette for a photo series, compare reference-based grades for a video sequence, or build a small library of tested starting looks. A reusable LUT is a starting point, not a guarantee that unrelated shots will match.

How to use

Choose a source and reference, check exposure and color-space assumptions, refine the look, keep a neutral baseline, and test the result on varied scenes and skin tones before production use.

Tips and pricing

A LUT does not recover clipped detail or replace color management. The current website offers free matching, fine-tuning and PNG previews; custom .cube export uses a credit. Check the current tier limits before exporting. I am associated with the project. Website: https://ailutgenerator.online/
