Multi-camera techniques involve using multiple cameras to simultaneously record or broadcast a scene from different angles. This allows for more footage to choose from during editing and capturing different views. The main genres that use multi-camera techniques are sports, concerts, public events, game shows, chat shows and magazine shows. While it provides advantages like flexibility and redundancy, it also requires more equipment and setup time. Examples discussed are the Olympics, which uses movable cameras to keep up with athletes, and EastEnders, a soap opera that films scenes from multiple angles to save time in editing.
