VJ Loops

Making a VJ loop means producing a short video clip that repeats seamlessly — its last frame must flow into its first with no visible jump. This guide walks through the complete beginner workflow: planning the length, choosing a visual, making the loop seamless, and exporting. If you want a hands-on first project instead, start with the first visual tutorial. 1. Pick a Loop Length That Matches the Music A loop should be long enough to feel musical and short enough to stay in memory. The rule of thumb is 4 to 30 seconds, matched to a whole number of bars at the set’s tempo: ...

These are the effects where the app is doing real 3D rather than drawing a clever pattern. Each describes a shape as a distance function and walks a ray into it, so the lighting, perspective, and occlusion are genuine. They cost more per pixel than the tunnels and stage effects, and they look it. Raymarched effects at a glance Catalogue 124 effects total, across eight groups Covered here Fractal Cosmos, Box Fold Dimension, Blob Fusion, Crystal Dimension, Quantum Grid, Organic Fluids, Tron Organic, Retro Sphere Rendering Signed-distance raymarching on the wgpu pipeline, with PBR lighting Cost Higher than the screen-space effects — use Performance Mode or a preview-quality drop while editing Looping Seamless; motion derives from loop phase, not wall-clock time Fractals Fractal Cosmos A kaleidoscopic fold — box fold plus ball fold — applied in the wall space of a tunnel, so the corridor you fly down is itself a fractal. Depth scrolls the fold rather than scrolling a texture, which is why detail keeps appearing at every scale as you approach instead of just getting bigger. ...

The 3D Tunnels group is now 18 effects, and it is the fastest route to a usable club loop in this app. They share a family resemblance — a corridor rushing at the camera, neon against black — but they are built differently, and the differences decide which one suits a given track or venue. The tunnel family at a glance Tunnels in the catalogue 18, inside a total of 124 effects Rendering wgpu compute/render pipeline, anti-aliased at every depth Looping Every tunnel closes on itself — no visible seam at the loop point Colour Any of the 187 palettes, plus projection and animation modes Typical output Seamless MP4 loops at up to 8K, or live via Spout/NDI What makes a tunnel look expensive Three things separate a convincing neon corridor from an obviously cheap one, and all three are handled in the shader rather than left to you: ...
