Comprehensive reference for video signal types used in glitch art setups.

Composite (CVBS)

The most common signal in glitch art. Carries all video information (luminance, chrominance, sync) on a single wire. Yellow RCA connector. Standard definition only (480i/576i). The simplicity of composite makes it resilient to glitching — signals degrade gracefully.

S-Video

Separates luminance (Y) and chrominance (C) into two signals. Cleaner than composite with less color bleeding. 4-pin mini-DIN connector. Many mixers support both composite and S-Video.

Component

Three separate signals (Y/Pb/Pr). Higher quality than composite or S-Video. Can carry HD signals. Red/green/blue RCA connectors (not the same as RGB).

VGA (RGBHV)

Analog computer video. Separate signals for Red, Green, Blue, Horizontal sync, and Vertical sync. 15-pin DE-15 connector. Useful for incorporating computer sources into analog chains.

HDMI

Digital video and audio on a single cable. The standard for modern video. Does not degrade gracefully — it either works or it doesn’t. Digital glitch artifacts are distinctly different from analog.

SDI (Serial Digital Interface)

Professional digital video over BNC cable. Used in broadcast and production. More robust than HDMI for long cable runs. Found on professional equipment like Blackmagic and Roland devices.

RF (Radio Frequency)

The signal carried over coaxial cable to TVs. Lowest quality but can be useful for intentionally degrading signals for aesthetic purposes.
