Illustrated Example
The following is a simplistic illustrated explanation of how motion compensation works. Two successive frames were captured from the movie Elephants Dream. As can be seen from the images, the bottom (motion compensated) difference between two frames contains significantly less detail than the prior images, and thus compresses much better than the rest.
| Type | Example Frame | Description |
|---|---|---|
| Original | Full original frame, as shown on screen. | |
| Difference | Differences between the original frame and the next frame. | |
| Motion compensated difference | Differences between the original frame and the next frame, shifted right by 2 pixels. Shifting the frame compensates for the panning of the camera, thus there is greater overlap between the two frames. |

Famous quotes containing the word illustrated:
“The adjustment of qualities is so perfect between men and women, and each is so necessary to the other, that the idea of inferiority is absurd.”
—“Jennie June” Croly 1829–1901, U.S. founder of the woman’s club movement, journalist, author, editor. Demorest’s Illustrated Monthly and Mirror of Fashions, p. 204 (August 1866)
“The creation of “strong-minded” women, so-called, is due to the individualism of men, to the modern selfish and speculative spirit which absorbs everything within itself and leaves women nothing but self-assertion for their protection and support.”
