What defines the setup of a three-camera production?

In a three-camera production setup, having all cameras feed live streams to the switcher is a key feature that allows for dynamic and immediate switching between different camera angles during a live event or broadcast. This approach enables a seamless flow of the presentation, as the director can choose which camera to use in real time based on the action occurring on set.

This method is particularly advantageous in situations such as live sports, concerts, talk shows, or any event where there is a need to capture multiple viewpoints without interrupting the flow for post-production editing. The switcher allows the production team to create an engaging viewing experience by readily alternating between different perspectives, leading to a more cohesive and professional broadcast.

In contrast, while multiple angles can be shot and edited later or cameras can be used to focus on different subjects, these methods do not leverage the full benefit of a live switching setup that characterizes three-camera operations. The presence of a main camera with supporting cameras typically refers to a more hierarchical structure rather than the integrated live-streaming aspect that is central to the three-camera technique.
