3D LUT Video and Photo Color Grader

3D LUT Video and Photo Color Grader is a desktop .cube 3D lookup table color grading studio,
LUT inspector, custom .cube generator, and batch media processor for Linux powered by FFmpeg.
An independent Linux alternative to FXhome HitFilm's color grading and LUT workflows, it parses
and generates standard Iridas/Adobe .cube 3D LUT files, previews looks with a live before/after
split wipe and measured 256-bin RGB histogram, and exports graded videos and photos.

Key Features:
- 8 Bundled Mathematical 3D .cube Looks + Custom .cube Loader: Ships with 8 precision 3D .cube
color looks (Teal-Orange, Bleach Bypass, Warm Film, Noir Monochrome, Cool Cinema, Crisp
Rec709, Faded Matte, and Vivid Pop) and loads any external 1D or 3D .cube LUT file.
- Live Before/After Split-Wipe Preview & 256-Bin RGB Histogram: Compare ungraded vs lut3d
tetrahedral-interpolated frames interactively while inspecting live Red, Green, Blue, and
Rec.709 Luma channel distributions.
- Custom 3D .cube LUT Authoring & Lattice Inspector: Fine-tune LUT mix strength, temperature,
tint, lift, gamma, contrast, and saturation, inspect neutral transfer curves and N^3 lattice
diagnostics, and export reusable 17x17x17 or 33x33x33 .cube files.
- Video & Photo Grading via Bundled FFmpeg: Export graded MP4/MKV videos with audio stream copy
and high-resolution PNG/JPEG/WebP photos, plus 8-look visual contact sheet comparison.
