Motion

Definition

Specifies the level of motion you anticipate in a scene of interest.

Motion example: High Motion example: Low

Motion can come from the target (e.g., a car driving by), the background (e.g., a large crowd), or from the camera itself moving (e.g., a dash-mounted camera in a police car). Motion affects the length of time a desired target is shown in the video frame, and can cause the target to blur. High motion can be caused by either many moving objects within the scene or a single object moving quickly.

Scene Content

Lists motion consideration, scene, and content information.
