Scenario Video Color Grade

Overview

Every grade here is math the agent writes, measures, and tunes; no generative model touches the pixels. Per-pixel color operations bake into a 33³ .cube LUT that ffmpeg applies. Spatial operations (relight, keyed or masked selective color) run per frame in numpy before the LUT. Results are exact, identical on every frame, and editable: the LUTs load in Premiere, After Effects, and Resolve. Framing, motion, and frame count are kept, so a seamless loop stays seamless.

Scenario supplies two preset LUT tool models and the segmentation masks that make selective color exact. New footage is out of scope. Connection and the core loop: the scenario skill. Running the LUT tool models on long clips (cost follows the clip, wait=false): scenario-video-editing. Music for a reel: scenario-audio. If a sibling skill named here is missing from your available skills, load it with skill_get (Scenario MCP) or ask the user to install it (https://github.com/scenario-labs/skills#install); unattended, proceed from tool schemas and flag the gap.
