Xmp To Cube Converter Guide

This paper presents a practical, end-to-end framework for converting XMP-based color grading metadata into a 3D LUT (cube) format. We cover background on XMP and 3D LUTs, formalize the translation problem, propose an algorithmic pipeline, detail data models and interpolation strategies, discuss precision and perceptual considerations, and validate results with experiments and metrics. The goal is a reproducible, production-ready approach useful for colorists, post-production tools, and open-source converters.
