Glitch effect

Hyper-Chromatic Separation

Hyper-Chromatic Separation is a glitch video effect in FRCTL, the browser VJ studio. RGB channels travel through different spirals, pinches, and inflations.

Runs live on video, images, a camera or generated art. Stack it with any other effect, and route LFOs, envelopes or any of ten audio bands to its controls so it moves with the music.

What Hyper-Chromatic Separation does

Sends each channel through its own warp around the frame centre. Red twists into a spiral that tightens with distance and keeps slowly turning, green contracts toward the centre near the edges, and blue swells out of the middle. Where the three disagree the art splits into rainbow loops, while the pupil stays close to aligned. Spiral sets the twist, Pinch the green and blue scaling.

Using Hyper-Chromatic Separation

Where it works
Centred compositions such as a logo or a single eye, because the middle stays readable while everything around it comes apart. The spiral turns by itself, so it also holds up as a slow intro loop.
With the music
The red spiral already rotates on the effect clock, at the rate Speed sets. B2 (sub bass) on Pinch makes the frame breathe with the low end, and B7 (snare) on Spiral cranks the twist on each snare.
Starting point
Spiral at a quarter, Pinch at centre, Blend at three-quarters, Speed at a quarter, with the subject centred in frame.

Controls

Spiral
Red channel angular warp strength.
Pinch
Green/blue radial scale warp depth.
Blend
Final chroma separation vs original.
Speed
Rate of the effect motion. Centre is the authored speed, hard left a tenth of it.
