The Technicolor look, reconstructed from the real process.
Nx 3-Strip reconstructs Technicolor Process No. 4 from first principles — the three-strip camera, the dye-transfer print, and everything physical in between — computed per pixel, on the GPU. From subtle dye glow to mechanical registration jitter, it turns sterile digital footage into a living, breathing photochemical image.
Version 3.0 re-derives every stage of the reconstruction from new primary evidence — scans of original three-strip camera negatives, period dye-transfer prints and native-4K restorations, measured frame by frame — and adds nine film presets, HDR output and new Tint and Highlight Warmth controls.

Key features
Nine looks measured from reference films — Nx Reference, Three-Strip Standard, six film-specific looks and Camera Negative. A preset changes the look and nothing else.
Un-mixes the broad overlapping channels of a digital sensor into the razor-sharp #25 / #58 / #47 primaries of a real three-strip camera.
Three spectrally-derived CMY coefficients calibrated against spectrally measured Process IV dyes. Saturated colors darken rather than bloom — true subtractive density.
Dyes transfer Cyan → Magenta → Yellow into gelatin that resists each successive layer. Cool shadows and warm highlights, grown in chemistry.
Per-channel halation from the actual bipack optical path, applied in the exposure domain before the film curve. Warmth from physics, not a tint.
Edge snap and midtone depth before dye processing; fine surface texture diffused while edges stay intact — the dimensional look of real IB prints.
Negative grain before the film response, imbibition print grain after — neutral dye texture that rides the weaving frame, never chromatic noise.
Per-record misregistration, temporal drift, printer jitter, film shrinkage, Geneva-drive gate weave and color breathing.
HDR PQ (Rec.2020) output with an HDR Peak control from 300 to 1000 nits in Resolve and Adobe hosts. Shadows and mid-tones match the SDR render exactly; only the highlight headroom opens up.
Rec.709/P3/Rec.2020, ARRI LogC3/4, S-Log3, RED, Canon, V-Log, F-Log2, D-Log, Apple Log, ACEScct, Cineon, DaVinci Intermediate, linear EXR and more.
Separations, dye layers, response curves, halation and grain maps — every panel driven by the same math as the render.
Scrubbing, render farms and re-renders produce bit-identical frames, every time.
