Video Switcher

Definition

A video switcher is an electronic device used in television production to select and switch between different video sources, such as cameras, graphics, or pre-recorded videos. This tool allows producers and directors to control live broadcasts by transitioning smoothly from one source to another, enhancing the overall presentation of the broadcast. Video switchers can be hardware-based or software-based and often include features for adding effects, transitions, and overlays to the footage.
