A '''vision mixer''' is a device used to select between different live [[video]] sources and, in some cases, [[compositing]] live video sources together to create [[visual effect]]s.

In most of the world, both the equipment and its operator are called a vision mixer or '''video mixer'''; however, in the [[United States]], the equipment is called a '''video switcher''', '''production switcher''' or '''video production switcher''', and its operator is known as a [[Technical director#Television|technical director]].

The role of the vision mixer for video is similar to what a [[mixing console]] does for audio. Typically a vision mixer would be found in a [[video production]] environment such as a [[production control room]] of a [[television studio]], [[production truck]] or [[post-production]] facility.
