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:
“Too many Broadway actors in motion pictures lost their grip on success—had a feeling that none of it had ever happened on that sun-drenched coast, that the coast itself did not exist, there was no California. It had dropped away like a hasty dream and nothing could ever have been like the things they thought they remembered.”
—Mae West (1892–1980)
“Many old people receive pensions for no other reason, it seems to me, but as a compensation for having lived a long time ago.”
—Henry David Thoreau (1817–1862)
