What is a Bus in the context of video production?

In video production, a bus refers to a system used for selecting and routing video sources during live broadcasts or recordings. It allows operators to switch between different video feeds, enabling them to create a cohesive and seamless final output. The bus functions as a central hub where multiple inputs can be monitored and controlled, facilitating live switching and transitions between sources. This is essential for live events, television broadcasts, and multi-camera productions, where real-time decision-making is crucial for maintaining a smooth flow of the program.

The other choices do not accurately reflect the role of a bus in video production. A type of camera or a production budget allocation tool does not relate to the technical aspect of switching and routing video signals. Additionally, while visualization tools may aid directors in planning and conceptualizing scenes, they do not serve the live operational function that a bus provides during production.
