Motion compensation is an algorithmic technique employed in the encoding of video data for video compression, for example in the generation of MPEG-2 files. Motion compensation describes a picture in terms of the transformation of a reference picture to the current picture. The reference picture may be previous in time or even from the future. When images can be accurately synthesised from previously transmitted/stored images, the compression efficiency can be improved.

Famous quotes containing the words motion and/or compensation:
“The motion picture is like a picture of a lady in a half- piece bathing suit. If she wore a few more clothes, you might be intrigued. If she wore no clothes at all, you might be shocked. But the way it is, you are occupied with noticing that her knees are too bony and that her toenails are too large. The modern film tries too hard to be real. Its techniques of illusion are so perfect that it requires no contribution from the audience but a mouthful of popcorn.”
—Raymond Chandler (1888–1959)
“Senators and presidents have climbed so high with pain enough, not because they think the place specially agreeable, but as an apology for real worth, and to vindicate their manhood in our eyes. This conspicuous chair is their compensation to themselves for being of a poor, cold, hard nature.”
—Ralph Waldo Emerson (1803–1882)
