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:
“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)
“... the compensation for a death sentence is knowledge of the exact hour when one is to die. A great luxury, but one that is well earned.”
