What device is used to support the camera and keep it stable?

The tripod is the device specifically designed to support the camera and maintain its stability. It typically consists of three legs and a mounting head that allows for adjustments and smooth panning or tilting. The stability provided by a tripod is crucial in preventing unwanted camera shake during recording, which can significantly enhance the quality of the footage.

A crab dolly, while it allows for smooth movement along a track, does not inherently stabilize a camera on its own; it is more about mobility. The pedestal is a type of support that can lift a camera but usually is part of more complex setups. A dolly grip refers to a person who operates the dolly, ensuring its movement is synchronized with the camera operation, rather than a device itself meant solely for stability. Thus, the tripod stands out as the primary tool for achieving a stable shooting setup.
