How It Works
Motion compensation exploits the fact that, often, for many frames of a movie, the only difference between one frame and another is the result of either the camera moving or an object in the frame moving. In reference to a video file, this means much of the information that represents one frame will be the same as the information used in the next frame.
Using motion compensation, a video stream will contain some full (reference) frames; then the only information stored for the frames in between would be the information needed to transform the previous frame into the next frame.

Famous quotes containing the word works:
“Separatism of any kind promotes marginalization of those unwilling to grapple with the whole body of knowledge and creative works available to others. This is true of black students who do not want to read works by white writers, of female students of any race who do not want to read books by men, and of white students who only want to read works by white writers.”
—bell hooks (b. 1955)
