Liquid effect

Ooze

Ooze is a liquid video effect in FRCTL, the browser VJ studio. Long liquid trails that hang off whatever is lit. Nothing runs out of black.

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 Ooze does

Long threads of liquid hang off anything lit or colourful and run down the frame, while black and neutral dark grey stay put. Each thread necks, beads and swells until a drop lets go, then springs back. Reach sets trail length, Melt how dark a pixel can be and still run, Flow the drip cycle speed, Bleed how far the channels separate, and Wander the sideways drift.

Using Ooze

Where it works: Cover art and logos on black, where everything lit drips and the background stays clean because trails can only add light. Also the drip to reach for on a slow, heavy drop.
With the music: Reach suits B2 (sub bass): trails lengthen with the sub and retract in the gaps. An Envelope from the beat on Melt lets darker parts of the image start dripping on each hit.
Starting point: Reach centre, Melt a quarter, Flow a quarter, Bleed centre, Wander a quarter, Gloss centre, Direction on Down.

Controls

Reach: How far the drips fall. Past about three quarters they run off the bottom.
Melt: How dark a pixel can be and still run. Hard left melts only the brightest.
Flow: Rate of the whole drip cycle -- swelling, beads running down, drops letting go.
Bleed: How far the colour channels separate as they fall, which is what mixes them.
Wander: Sideways drift as the material falls.
Gloss: Wet highlight down the side of each thread, chroma, and the hot core.
Direction: Which way the material runs off.
Speed: Rate of the effect motion. Centre is the authored speed, hard left a tenth of it.
