ComfyUI-VideoColorGrading

ComfyUI implementation of Video Color Grading via Look-Up Table Generation (ICCV 2025).

Generates a 3D color LUT from a reference image and source video frames using a two-stage diffusion process, then applies it for consistent color grading.

Nodes

• Load VCG Model - Loads the combined model checkpoint (CLIP ViT-B/32, VAE, ReferenceNet, L-Diffuser)
• Generate Color LUT (VCG) - Generates a 16^3 3D LUT from reference image + source frames
• Apply 3D LUT (VCG) - Applies the generated LUT to images
