Audio-follow-video Switcher

Audio/Video Glossary - Audio-follow-video SwitcherDuring video production, the video signal is normally accompanied by an audio signal. Sometimes, during the switching or processing of signals, the audio signal is separated from the video signal. In such a case, a complex situation arises whereby each signal must be processed, mixed and enhanced separately. Audio-follow-video is a process which overcomes this difficulty and both signals, audio and video, are switched from an audio-video source to an audio-video acceptor simultaneously (not in separate passes).
