Learn Video Synthesis
What is a video synthesizer?
A video synthesizer is an electronic instrument that generates or processes video images in real time. A modular video synthesizer is built from small devices called modules mounted into an enclosure. Modules are patched together with cables; how they are patched determines what the synthesizer does.
For a deeper introduction, see What Is a Video Synthesizer? in the guides. For the story of LZX and our design philosophy, see About LZX.

Practical facts about LZX Modular
- Modules fit standard Eurorack cases and use 3.5 mm patch cables.
- Modules can be powered by a 12 V DC barrel adapter or by a Eurorack power supply.
- External video in and out use the same Composite and Component connections as most televisions and many cameras.
- Patchable signals run from 0 V to +1 V; inputs tolerate any voltage a Eurorack system will produce.
- Control-voltage inputs are wide-bandwidth, so camera images and oscillators can modulate each other freely.

Key concepts and vocabulary
Video synthesis borrows terms from modular audio, broadcast video, and analog computing. Rather than restate definitions here, we maintain a single reference:
- Glossary — ramp generators, VCOs, frame synchronizers, comparators, encoders, keyers, and the rest of the shared vocabulary.
- Standards — the electrical, mechanical, and video-format conventions behind LZX Modular.

Where to next
- Set up a system. Start with Modular walks through installation, your first patch, and troubleshooting.
- Set up Videomancer. If you bought the standalone instrument, jump to the Videomancer Quick Start Guide.
- Pick hardware. Compare every active module at Module Specs, or browse Starter Systems for curated builds.
