full-motion video

(FMV) Any system used to deliver moving video images and sound on a computer. Video images and sound are stored on disk; compact disc is preferred because of the amount of data required. Some form of video compression is used to reduce the amount of data and to allow it to be read from disk quickly enough. Compression can be relatively slow but decompression is done in real-time with the picture quality and frame rate varying with the processing power available, the size of the picture and whether it appears in a window or uses the whole screen.

Acorn Computers' system is called Replay and Apple Computer's is QuickTime.

Compare MPEG, H.261.

full-motion video

Video transmission that changes the image 30 frames per second (30 fps). Motion pictures are run at 24 fps, which is the minimum frequency required to eliminate the perception of moving frames and make the images appear visually fluid to the eye.

TV video generates 30 interlaced frames per second, which is actually transmitted as 60 half frames per second.

Video that has been digitized and stored in the computer can be displayed at varying frame rates, depending on the speed of the computer. The slower the computer, the more jerky the movement. Contrast with freeze-frame video.
