A video is a visual medium used to convey information, tell a story, or capture a moment in time through a series of moving images. It typically includes sound, either recorded separately or as part of the video itself, and can range in length from a few seconds to several hours. Videos can be recorded using a variety of devices, including cameras and smartphones, and can be shared and distributed through various channels, such as social media platforms, video sharing sites, and streaming services. Videos have become a popular form of entertainment, education, and marketing, and are widely used in industries such as film and television, advertising, and journalism.
