Motion Compensation in MPEG
In MPEG, images are predicted from previous frames (P frames) or bidirectionally from previous and future frames (B frames). B frames are more complex because the image sequence must be transmitted/stored out of order so that the future frame is available to generate the B frames.
After predicting frames using motion compensation, the coder finds the error (residual) which is then compressed and transmitted.

Famous quotes containing the words motion and/or compensation:
“No motion has she now, no force;
She neither hears nor sees;
Rolled round in earth’s diurnal course,
With rocks, and stones, and trees.”
—William Wordsworth (1770–1850)
“In compensation for considerable disgust, despondency, and boredom—such as living in solitude without friends, books, duties, or passions necessarily entails—we are given those quarter-hours of deepest communion with ourselves and nature. Those who completely barricade themselves from boredom, barricade themselves from themselves as well: they will never get to drink the most refreshingly potent draught from the their own innermost fountain.”
—Friedrich Nietzsche (1844–1900)
