"dolly" 的定义和意义

What is a "dolly"?

A dolly is a piece of equipment used to move a camera smoothly and steadily during a shoot. It is a platform on wheels or tracks that holds the camera and can be pushed or pulled by the crew. This allows the camera to follow the action, create dynamic shots, and capture scenes from different angles without any shaking or jerking. Dollies help filmmakers achieve professional and polished visual effects in their movies or videos.
