Video generally refers to various technologies that capture, record, process, store, transmit and reproduce a series of still images in the form of electrical signals. When the continuous image changes exceed 24 frames per second, according to the principle of persistence of vision, the human eye cannot distinguish a single static image; it looks like a smooth and continuous visual effect, and such continuous images are called videos. Video technology was first developed for television systems, but has evolved into a variety of formats for consumers to record video. The development of network technology has also prompted video documentary segments to exist on the Internet in the form of streaming media and can be received and played by computers. Video is a different technology than film, which uses photography to capture moving images as a series of still photos.
