Liquid effect

Jellyfish Bloom

Jellyfish Bloom is a liquid video effect in FRCTL, the browser VJ studio. Soft expanding rings invert colors with watery distorted edges.

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 Jellyfish Bloom does

Soft rings expand outward from the centre on a loop, and inside each ring the colours invert, a rainbow rim glows, and the picture bulges outward with a watery wobble. Between rings the image shows through with only a slight ripple. Rings sets how many are in frame, Water the bulge and wobble, and Bloom the inversion and rim.

Using Jellyfish Bloom

Where it works
Centred compositions like a logo, an eye or a DJ portrait in the middle of the frame, where outward pulses frame the subject. It suits downtempo sets and intros.
With the music
B3 (bass body) on Bloom flares the inversion with the bassline while the rings keep their own pace. An Envelope from the beat on Water gives every kick a watery shove.
Starting point
Rings a quarter, Water centre, Bloom a quarter, then raise Bloom until each passing ring flips the colours clearly.
