What term describes the act of moving the camera to scan the set horizontally?

The term that describes the act of moving the camera to scan the set horizontally is "panning." Panning involves swiveling the camera left or right on a fixed base, allowing the viewer to follow action or see more of the environment without physically moving the camera location. This technique is widely used in film and video production to create a sense of movement or to guide the audience's attention across the scene.

The other options refer to different camera movements: tilting involves moving the camera up or down around a horizontal axis; trucking refers to moving the camera physically closer or farther away from the subject, typically along a track; and pedsaling (often called dolly in or dolly out) specifically describes the action of moving the entire camera setup forward or backward, rather than just rotating it. Understanding these distinctions is important for effectively utilizing camera movements in film and video production.
