Dolly track意思

"Dolly track" is a term used in the film and video production industry. It refers to a specialized track or rail system used to support a camera dolly, which is a platform that allows a camera to move smoothly along the track. The dolly track is used to create smooth camera movements such as tracking shots, where the camera appears to be moving through a scene while filming. This can add depth and dynamic movement to a scene, making it more engaging for the viewer. Dolly tracks can be made of various materials such as aluminum, steel, or even plastic, and can be straight, curved, or adjustable to fit different shooting needs.
