Frame Rate
Last updated on Dec 27, 2018
The video frame rate per second. The number of still images that are displayed in a given time interval to provide the illusion that the images are moving. A typical frame rate is 24 frames/second. (PAL uses 25fps while NTSC uses 29.97). Each picture of a video – either a frame or a field – is partitioned into as many macroblocks as necessary to cover the picture area. These macroblocks serve as the basic element for operations such as spatial/temporal compression, motion compensation, and re- encoding.
