Flow Viz applied to FRCTL's test image: The measured motion field itself, direction as hue and speed as value.

Pulse & motion effect

Flow Viz

The measured motion field itself, direction as hue and speed as value.

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.

Palette
Monochrome speed at zero, direction-as-hue at one.
Sense
How little texture counts as motion worth measuring.
