Why we like it

Stands out in the aescripts library because it reconstructs the Technicolor look from film physics rather than relying on a LUT.

What is Nx 3-Strip?

Nx 3-Strip is a color effect for DaVinci Resolve from Nx Color that reconstructs the Technicolor Process IV, built from film physics rather than a LUT. It aims for the dense, dimensional look of three-strip photography through emulation of the process itself.

The result carries narrow-band color separation that carves each hue clean, dense and heavy saturation where saturated colors darken rather than brighten, and rich color contrast with an oil-paint sense of dimensionality. Skin reads with golden tones from cyan dye impurity, highlights take on an ivory cream tone, and shadows run cool while highlights run warm — the imbibition trapping signature. Deep, structured blacks, organic highlight rolloff and density-dependent grain round out the film character.

Nx 3-Strip is at version 2.2 and works with DaVinci Resolve 21, 20 and 19. It's listed here as free; check the developer's page for current licensing.

Who is Nx 3-Strip best for?

Nx 3-Strip is best for colorists working in DaVinci Resolve who want a Technicolor Process IV look reconstructed from film physics.

How much does Nx 3-Strip cost?

Nx 3-Strip is completely free to download and use.

Key features

  • Narrow-band filtering separates each hue for clean color separation
  • Dense, heavy saturation where saturated colors darken rather than brighten, with oil-paint dimensionality
  • Golden skin tones from cyan dye impurity and ivory cream highlight tone from differential dye thinning
  • Cool shadows and warm highlights — the imbibition trapping signature
  • Deep, structured blacks with Matrix Key definition in shadows, plus organic highlight rolloff from gelatin transfer threshold and D-Min
  • Three-dimensional pop from IB print acutance and lateral dye inhibition emulation, with painterly mid-frequency softness
  • Per-channel fringing for dimensional registration and density-dependent grain with no chromatic noise

Frequently asked questions

Does Nx 3-Strip work with DaVinci Resolve 19?

Nx 3-Strip supports DaVinci Resolve 21, 20 and 19, so it runs across three recent release lines of the software. If you're on one of those versions, it should slot into your grading setup. For versions outside that range, check the developer's page before installing, since compatibility beyond Resolve 19 through 21 isn't listed. Confirming your Resolve version first is the simplest way to know whether Nx 3-Strip fits your current workflow.

Does Nx 3-Strip use LUTs?

Nx 3-Strip is described as a Technicolor Process IV reconstruction built from physics rather than LUTs. Rather than a lookup table, it draws on characteristics of the three-strip process — narrow-band color separation, dye behaviour, imbibition trapping and film density — to produce its look. That physics-based approach is central to how the effect is generated. For deeper detail on how the reconstruction is applied inside DaVinci Resolve, the developer's page is the place to look.

Is Nx 3-Strip free?

Nx 3-Strip is listed here as free. We don't publish a price figure, and licensing terms can change, so the developer's page on aescripts is the best place to confirm current availability and any usage conditions before you download. That keeps you working from the latest information. Based on how it's listed, it's a straightforward way to try the Technicolor Process IV look in DaVinci Resolve without a cost commitment.

What's new in Nx 3-Strip 2.2?

Nx 3-Strip is at version 2.2, released on May 12, 2026, which the changelog marks as its initial release. As an initial release, there isn't a prior version history to compare against yet, so the current build is the starting point for the plugin. It works with DaVinci Resolve 21, 20 and 19. If you want to track future updates or read the full release notes, the developer's page on aescripts is where that information is maintained.
