Light & lasers effect

Lasers High

Lasers High is a neon and laser effect in FRCTL, the browser VJ studio. Concert-style laser fans from both top corners.

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 Lasers High does

The same five-beam fans as Lasers Low, hung from the top corners and pointing down and inward, so the beams rain across the frame and cross in its lower half. Each beam swings and twitches on its own timing, and the fans reach further toward the floor as Beams rises. Sweep widens the fan and the swing, and Hue defaults to magenta rather than Low's green.

Using Lasers High

Where it works
Pick High for the ceiling-truss look, light raining down onto whatever sits below, and when the top corners hold sky or empty space. It suits breakdowns and covers where the beams should point down at the subject.
With the music
Beams swing on the effect's own clock. An Envelope triggered by the beat on Sweep flings the fans wide on each hit and lets them close between, and B2 sub bass on Beams stretches them further toward the floor.
Starting point
Beams at three-quarters, Sweep at centre, Speed at a quarter, so long beams drift down from the top corners.
