PHASELIGHT
Load a scene. Mod everything. Take the look. GPU shaders, 3D dioramas, fluid, projection shapes and live media — mixed on a clip grid, driven by audio, taken live and streamed anywhere.
One instrument · every surface
A whole rig on a clip grid
Columns are looks, rows are layers. Six engines, one console — patch them together and drive the whole wall from the CUE deck.
Shader engines
100+ GPU shaders plus your own GLSL — generative, kaleidoscopic, image-sampling — all running live at framerate.
3D dioramas & fluid
glTF scenes with rigged beings and cinematic staging, real-time fluid and particle fields that flow with the set.
Clip grid + Cue/Take
Stage the next look on CUE, then commit with TAKE — instant, crossfaded or A/B swap. The floor never sees you work.
Mods
16 LFOs → unlimited targets
Plus audio envelopes, beats and full spectrum. Route-learn any parameter in a click and the whole rig breathes on its own.
Shapes / projection
HeavyM-style outlines and fills over shared layouts. Trace the venue once — image, webcam or live output — then switch looks live.
Outputs
Virtual camera, NDI network video and window split to a clean second display — into OBS, a switcher, a projector or the wall.
See it move
Built like an instrument
Not a slideshow — a lighting desk. Every panel is live and hands-on. Click any monitor to zoom in.
One clean master out
The finished frame the room sees — every engine, FX and shape composited and rendered at framerate, ready for the wall, a projector or the stream.
Put it on a clock
A beat-quantized column sequencer with per-row lanes and BPM transport. Tap tempo or lock to MIDI clock and let the set run itself.
16 LFOs, unlimited targets
Every macro assignable to any number of parameters, plus audio envelopes and spectrum. Route-learn a control and it breathes on its own.
Trace the room, once
Vector tools, snap and mirror, background tracing over image, webcam or live output — and one-click auto-trace from image contours.
How a set flows
Three moves, endlessly
Cue the next look
Pick engines, dial FX, arm a HITS gesture. It stays private on the CUE deck until you commit — the floor sees nothing.
Make it move
Bind 16 LFOs, audio envelopes and MIDI to any parameter. The look breathes with the music before you ever push it live.
Commit on the beat
Hit TAKE to push it live — instant, crossfaded or A/B swap. The sequencer can fire it for you, quantized to tempo.
Get it out of the box
Made for stages & streams
Phaselight shows up as a webcam and streams full-framerate over the network — no capture-card gymnastics. Drop it straight into your broadcast.
Virtual camera
Phaselight appears as a webcam in OBS, Zoom and Discord — one-click install, no capture card.
ProNDI output
Full-framerate, GPU-scaled network video to any NDI-ready switcher or machine on your LAN.
ProOBS & window split
A clean full-screen output on a second display with a live confidence monitor — straight into OBS or the projector.
CoreCore vs Pro
Everything to perform, free
The whole instrument lives in the free Core tier. Pro adds the broadcast outputs — and right now it costs nothing.
