What is a tripod typically used for in video production?

A tripod is primarily used to stabilize the camera, providing a solid base that minimizes unwanted movements during a shoot. This stability allows for smoother shots, especially in situations where the camera needs to remain stationary for static scenes or long takes. By keeping the camera steady, a tripod helps maintain the framing and composition of the shot, which is crucial in video production for creating a professional look.

The other options involve functions that are typically not related to tripod use. For instance, capturing moving subjects is usually accomplished with handheld shooting or tracking equipment rather than a stationary tripod. Increasing the camera's sensitivity to light is a function of the camera's sensor and settings, not something a tripod can influence. Quick lens changes are normally performed on the camera body without the assistance of a tripod, as a tripod’s role is not related to lens management but rather to providing stability.
