Extract a color palette from any reference image and render it as a 3D LUT (.cube file) you can apply to footage in ffmpeg, Premiere, DaVinci Resolve, or Final Cut. Sample any movie still, album cover, or photo and turn its grade into a reusable LUT. Also previews the LUT applied to a target video. Use when the user wants to color match footage to a reference, generate a LUT from an image, recreate a movie's grade, or apply a film look to their clip.

Sample a reference image's color palette and bake it into a usable .cube LUT.
Run
# 1) Extract LUT from a reference still
python3 ~/.claude/skills/lut-snap/scripts/lut_snap.py extract \
--ref ref_image.jpg --out my_grade.cube --size 33
# 2) Apply it to footage
python3 ~/.claude/skills/lut-snap/scripts/lut_snap.py apply \
--lut my_grade.cube --input clip.mp4 --out graded.mp4
# 3) One-shot: extract + apply
python3 ~/.claude/skills/lut-snap/scripts/lut_snap.py snap \
--ref ref.jpg --input clip.mp4 --out graded.mp4 --lut-out grade.cube
How it works
- Sample 5000+ pixels from the reference image.
- Build a color transfer using histogram matching per RGB channel against a neutral identity grid.
- Export as a 33x33x33 .cube LUT (industry standard).
- ffmpeg's
lut3dfilter applies it to any video.
Notes
- LUTs work in Premiere / Resolve / Final Cut by importing the
.cubefile. - For nuanced grades use
--size 65(slower but smoother). - Reference images should already be color-graded (movie stills, album art, IG photos).
