What does the camera movement termed 'truck' involve?

The term 'truck' in camera movement refers specifically to moving the entire camera parallel to the set. This technique allows the camera to follow a subject laterally or to reposition within the same plane without changing the angle of view, which provides a dynamic way to capture action or reveal different aspects of a scene. This lateral movement can create a more immersive experience for the audience, as it can enhance the sense of space and proximity between the camera and the subjects being filmed, effectively adding to the visual storytelling. Other movements like raising and lowering the camera, rotating it, or zooming in and out serve different purposes in cinematography but do not align with the definition of 'trucking.'
