AI disclosure (per the Forum Resource and IP Policy): This script was developed with AI coding assistants operated and directed by the maintainer. Version 3.0.0 was developed with substantial assistance from Anthropic Claude (Lua code, the effect shader, the automated test tooling and documentation drafts); earlier versions used OpenAI Codex for individual fixes. The maintainer reviewed the changes and verified them with an automated test-suite and manual tests in OBS Studio 32.1.2 before release.

⚡ Main Features

Color Correction

• Tone: Exposure, Contrast, Brightness, Highlights, Shadows, Whites, Blacks – luminance-weighted, so tone changes do not shift hues
• Fade & Lift: Highlight Fade, Shadow Fade, Black Lift for matte and bleach film looks
• White Balance & Color: Temperature, Tint, Saturation, Vibrance

Color Grading

• Color wheels: separate RGB offsets for shadows, midtones and highlights (Lift / Gamma / Gain)
• Split toning: independent color and strength for shadows and highlights
• 3D LUTs: load .cube files of any size or .png LUTs (OBS 512x512 grid) with adjustable strength – Windows, macOS and Linux

Creative Effects & Workflow

• Bloom, Halation, Sharpen, animated Film Grain, Vignette with radius, feather and shape
• Mask: apply the whole grade only inside an ellipse or rectangle with soft edges
• 47 presets (Basic, Style, Mood, Era, Creative) that apply instantly, plus "Reset all"
• Looks: save and load all color settings as JSON to share between scenes, profiles and computers
• LUT export: bake your look into a 33³ .cube or an OBS-compatible 512x512 .png LUT
