Glitch effect

Subpixel Shockwave

Subpixel Shockwave is a glitch video effect in FRCTL, the browser VJ studio. Expanding chromatic shockwaves with edge displacement.

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 Subpixel Shockwave does

Two rings expand from the frame centre and restart with the loop, the second trailing the first at lower strength. At each ring the channels warp radially, red outward and blue inward, and a rainbow rim rides the wavefront. Between rings the image is left alone. Shock sets the warp and ring strength, Spectrum the rainbow rim, and Speed how fast the rings travel.

Using Subpixel Shockwave

Where it works: Centred logos and single-subject covers, where a ring passing over the mark reads as an impact. Routed to the kick, it marks a drop or a big hit in a live set.
With the music: The rings follow the loop, not the beat. B1 (kick) on Shock keeps them faint until a kick lands, and B10 (sparkle) on Spectrum brightens the rainbow rim with the top end.
Starting point: Shock at three-quarters, Spectrum at centre, Blend at centre, Speed at centre, with the logo centred in frame.

Controls

Shock: Ring shock strength and chromatic warp.
Spectrum: Spectral rim add on the shock.
Blend: Blend toward the shocked color.
Speed: Rate of the effect motion. Centre is the authored speed, hard left a tenth of it.
