How Do I Turn a Live VU Meter or Waveform Into Laser Lines?

In Video to Laser, open LIVE, choose VISUALIZER, and select VU METER. Play the demo track. The needle swings with the music, and GEOMETRY sends the needle and arc straight to the laser preview as lines. You can try the whole workflow in the browser preview.

Oscilloscope Glow in the Cinema preview. The loop is silent. Start the demo track in the app to hear what drives the waveform.

What changes when I switch from EDGES to GEOMETRY?

With VU METER still playing, set LASER PREVIEW to 2D and switch TRACE between EDGES and GEOMETRY. Watch the needle and the meter's arc. EDGES finds brightness boundaries in the rendered picture, so a wide stroke can turn into an outline. GEOMETRY gets the original lines and colors from the visualizer. That makes it a good starting point when the subject is already drawn as lines.

Left is EDGES. Right is GEOMETRY. Both recordings use VU Meter and the same demo track at different playhead positions.

How do I switch from the needle to a waveform?

1. In the VISUALIZER picker, choose OSCILLOSCOPE GLOW. Keep the track playing.
2. Under TRACE, select GEOMETRY. In 2D, watch the line change shape as the track plays.
3. Switch LASER PREVIEW to CINEMA to see the waveform in a simulated venue. Raise ATMOSPHERE → Fog to see the beams, or drag the preview to look from another angle. Go back to 2D when you want to inspect the line again.

If the trace gets too busy, check POINT BUDGET during a louder passage. Move SIMPLIFY a little and check the 2D preview again. Stop when further changes start flattening the detail you want to keep. In GEOMETRY, DETAIL and AUTO do not change the supplied lines.

The Video to Laser guide lists other visualizers that support GEOMETRY, including Spectrum Analyzer in LINE mode. For video clips you want to save as laser animations, follow the tutorial on steadier video-to-laser outlines.
