Multiple-camera frame mode offers the advantage of depicting action from multiple angles and giving the viewer a 360-degree view of the action, rather than viewing it from one perspective. It allows for the capture of action that would otherwise occur off-screen.
When used in reviewing surveillance footage, multiple-camera frame viewing can indicate when activity occurs in a location and when to switch frames. It can reveal such details as where and when an intruder entered an area, when individuals make contact or when a suspect drew a weapon.
When used for reviewing sporting events, it can indicate when to slow the camera speed to review details to indicate whether a player was in bounds when catching a ball, whether a fan interfered with a play, or whether a runner avoided a tag.
When used as an editing tool, multiple-camera framing makes it easier to determine where to edit footage for the greatest continuity and dramatic effect, and to determine the effect of switching perspective. It can also indicate whether single-camera action is better suited to capturing a particular mood or action in a scene.
