vision mixer : ウィキペディア英語版 | vision mixer
A vision mixer (also called video switcher, video mixer or production switcher) is a device used to select between several different video sources and in some cases compositing (mix) video sources together to create special effects. This is similar to what a mixing console does for audio. The terms ''vision mixer'' and ''video mixer'' that describe both the equipment and the device operator are used outside the USA. In the United States, the equipment is called a ''video production switcher'' and the device operator is known as a technical director (TD) that is part of a television crew. == Term usage ==
Typically a vision mixer would be found in a video production environment such as a television studio, production truck, OB Van or linear video editing bay of a post-production facility.
