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:
“Happier of happy though I be, like them
I cannot take possession of the sky,
Mount with a thoughtless impulse, and wheel there,
One of a mighty multitude whose way
And motion is a harmony and dance
Magnificent.”
—William Wordsworth (1770–1850)
