Perceptual Video & LUT Reverse-Engineering Engine Matching the color grade of a reference film frame onto your own raw or log footage usually takes hours of manual curve tweaking, while AI style-transfer tools ruin video with flicker and pixel artifacts. Although extracting a grading pipeline from a compressed video seems mathematically impossible because the original camera data is baked in, ChromaInvert solves this using differentiable inverse rendering. Instead of altering pixels directly, it runs your source footage through a PyTorch-based trilinear 3D LUT shader, using semantic segmentation to anchor skin tones and shadows while optimizing lattice weights via gradient descent to match the reference's perceptual color distribution and vectorscopes. In seconds, it exports a smooth, industry-standard ⁠.cube⁠ file ready for Premiere Pro, DaVinci Resolve, or mobile camera apps with zero AI artifacts.
