Why is understanding "persistence of vision" important for video production?

Understanding "persistence of vision" is crucial in video production because it is the phenomenon that enables viewers to perceive a series of still images as a continuous moving picture. When frames are shown in rapid succession, typically at a rate of 24 frames per second or more, the visual system retains each image for a fraction of a second. This retention allows the brain to blend the separate images into a seamless flow of motion.

In practical terms, this concept underpins the fundamental techniques of filmmaking and animation. If frames are presented too slowly, the viewer may perceive the gaps between images, resulting in a disjointed experience. Therefore, mastering persistence of vision is essential for achieving smooth motion in film and video, greatly impacting the audience's engagement and perception of the narrative.
