video

A video is a sequence of images, called frames, displayed rapidly one after another to create the illusion of motion. Each frame is a still picture, and when viewed at a high enough speed—typically 24 to 60 frames per second—the brain perceives continuous movement. Videos also include audio, which synchronized with the images, enhances the communication of information and emotion. They can be recorded, stored, and played back using various devices and formats, serving purposes from entertainment and education to advertising and communication. Essentially, a video combines visual images and sound to tell stories, present information, or entertain audiences.
