VJam Docs

VJam is a browser-based real-time video instrument. Bring in sound, stack visual presets, switch between Deck A/B, and use it for live performance, streaming, recording, or projection.

This guide covers the full workflow: getting started, audio input, presets, Deck A/B, recording, streaming, MIDI, mobile use, and troubleshooting. Start with “Getting Started” if you are new, or jump to “Troubleshooting” if something is not working.
