Create strobe
create_strobeCreates a full-frame color strobe flash that pulses on/off at a given rate, with adjustable duration and brightness, and optionally overlays onto a source video.
Instructions
Build a beat-syncable strobe / flash layer — a full-frame colour flash that pulses hard on/off, the signature live-VJ strobe effect. A square-wave LFO CHOP at the given Rate (Hz) drives a Level TOP's brightness so a Constant TOP (the flash colour, white by default) blinks; Duty sets the on-time fraction. With an input_path the flash is composited OVER that source (pulled in by a Select TOP, so it can live in another container); without one, the bare flash is output. Output is a Null TOP. Rate is free-running for v1 — bind the LFO's frequency to a beat CHOP later to lock it to the tempo.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| rate_hz | No | Strobe rate in flashes per second (Hz) — the LFO CHOP square-wave frequency. | |
| intensity | No | Brightness of the flash when it is on (0..1). Drives the Level TOP's brightness1. | |
| color | No | Flash colour as a hex string ('#ffffff' = white, the classic strobe). Sets the Constant TOP's RGB. | #ffffff |
| duty | No | On-time fraction of each cycle (0..1, 0.5 = even on/off). Mapped to the LFO CHOP's Bias, which rectangularises the square wave. | |
| input_path | No | Optional absolute path of a source TOP to flash OVER. Pulled in via a Select TOP (TD wires don't cross containers) and composited under the flash. If omitted, the bare flash is output. | |
| expose_controls | No | Expose live Rate / Intensity / Duty knobs bound to the right node parameters. | |
| parent_path | No | /project1 |
