Dolly Track, also called dolly rail or camera track, is a set of parallel rails laid on the ground or mounted to a structure that guides a camera dolly along a precise, repeatable path. The track ensures smooth, vibration-free camera movement and allows cinematographers to execute complex choreographed shots with exact repeatability across multiple takes.

Track comes in various configurations including straight sections for linear moves, curved sections for arcing movements, and modular systems that can be configured into custom paths to match the blocking and choreography of a scene. Professional track is engineered to extremely tight tolerances to eliminate any wobble or unevenness that would be visible in the final footage. Laying track is a time-intensive process that requires leveling, precise alignment, and often extensive setup time, but the resulting camera movement is unmatched in smoothness and control compared to tracking on wheels alone.

In AI video generation, understanding dolly track helps creators communicate the type of controlled, precision camera movement they are aiming for. While AI models do not physically use track, referencing track-based movement signals that the camera motion should follow a defined, smooth path rather than drifting or floating unpredictably through space.
