Multi-camera productions use multiple cameras to film an event from different angles. This allows the production to capture close-ups, wide shots, and audience reactions all in one take. The advantages are less need for retakes and easier continuity, but it is more costly due to needing extra cameras, crew, and a vision mixer to control the different camera feeds. Roles in a multi-camera production include camera operators, a floor manager, director, vision mixer, sound engineer, lighting technician, and editor.
