A camera dolly track is a specialized piece of equipment used in filmmaking to create smooth and steady camera movements. The track consists of a set of rails, usually made of metal or plastic, which are placed on the ground or mounted to a platform.

The camera is mounted on a dolly, which is a small cart that rolls along the track. The dolly is typically equipped with wheels or ball bearings that allow it to move smoothly and quietly along the rails.

The length and configuration of the track can vary depending on the desired camera movement. Straight tracks are commonly used for simple back-and-forth or side-to-side movements, while curved tracks can be used to create more complex, circular or arcing movements.

Camera dollies can be manually pushed or pulled along the track, or they can be motorized for precise and repeatable movements. Some tracks also feature adjustable legs or leveling feet to ensure stability on uneven surfaces.

Camera dolly tracks are often used in conjunction with other camera stabilization tools such as tripods, cranes, and steadicams to achieve a variety of camera movements and perspectives.
