Builds a 3D .cube correction LUT from a single photo of a ColorChecker
calibration chart, via one of two premiere-ai commands (from the
premiere-ai package) — chart
detection (SAM3) and patch measurement are shared, but the two commands
fit fundamentally different corrections and are not interchangeable:
| Command | Chart page | Fits |
|---|---|---|
calibrate-lut |
Video-production page (Calibrite ColorChecker Passport Video 2) | Per-channel (R/G/B) tone curves for exposure/white-balance + a single global hue rotation for chromatic/skin-tone chips |
calibrate-lut-classic |
Traditional 24-patch page (X-Rite/Calibrite Classic) | A color-correction matrix (3x3 + offset, or an exposure-invariant root-polynomial) fit against published reference sRGB values |
