VHS / Hi-8 is a glitch video effect in FRCTL, the browser VJ studio. A worn home-video dub: soft colour smear, grain that changes every frame and a shaking tracking band, with a date-stamp flicker as it gets stronger.
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.
Smears red to one side and blue to the other for a soft colour bleed, adds per-pixel luma grain that refreshes every frame, and floats a darker, shaking tracking band near the middle of the frame. As the effect's strength rises, a flickering block pattern appears in the corner where a date stamp would sit. Bleed sets the smear width, Grain the noise, Tracking the band height and shake.
Using VHS / Hi-8
Where it works
Throwback intros, home-video cover art and Reels meant to look like a family dub. The smear stays gentle, so faces and type survive, which the heavier Tape Damage won't guarantee.
With the music
Grain and the band move by themselves. B9 (air) on Grain thickens the noise with the cymbals, and B3 (bass body) on Tracking makes the band jump on bass notes.
Starting point
Bleed at centre, Grain at a quarter, Tracking at centre, Speed at centre.
Controls
Bleed
Horizontal chroma smear width.
Grain
Luma noise and hash grain strength.
Tracking
Bad-tracking band height and shake.
Speed
Rate of the effect motion. Centre is the authored speed, hard left a tenth of it.
