video graphics
Moving images stored as a sequence of static images (called "frames") representing snapshots of the scene, taken at regularly spaced time intervals, e.g 50 frames per second. Apart from the frame rate, other important properties of a video are the resolution and colour depth of the individual images.
Video data is typically stored and transmitted in a format that includes synchoronised sound.
The many file formats in use for video differ chiefly in the type of compression used. Compression is even more important for video that for static images due to the large amount of data involved in even a short video. Furthermore, compression allows video to be transmitted via a channel whose bandwidth is less than the raw data rate implied by the resolution and frame rate. This allows the recipient to start displaying the video before the transmission is complete, a process known as streaming.
