The output of a video mixer is wired back to an input, allowing it to be manipulated using the mixer’s effects interface. A secondary output can be sent to a display. The patterns and forms on screen – created without the use of a camera – are generated purely from the video signal and the circuitry of the mixer. Expanding on these basic configurations, a feedback system can quickly grow in complexity by adding more links to the chain, by nesting loops, or combining both internal and external systems.
