Liquid effect

Warped Vinyl

Warped Vinyl is a liquid video effect in FRCTL, the browser VJ studio. Record-like spin with needle drag and noisy groove wobble.

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 Warped Vinyl does

Spins the picture around the centre like a record on a platter, twisting the outer rings further than the middle, while fine concentric grooves ripple every line into zigzags. Near the rim a needle drag pulls the image to one side. Groove sets ripple frequency and wobble, Spin the rotation speed and twist, Needle the drag strength, and Direction which way the needle pulls.

Using Warped Vinyl

Where it works
Anything about records: a vinyl release cover, a label logo sting, a set intro. The centre stays sharp while the edges churn, so a centred subject stays readable.
With the music
Spin is both speed and twist, so an Envelope from the beat on it gives each kick a brief surge, like a nudged platter. B8 (hats) on Groove makes the zigzags shimmer with the hi-hats.
Starting point
Groove a quarter, Spin a quarter, Needle centre, Direction on Left, then raise Groove until the lines just start to ripple.
