High-motion

High-motion

High motion is the characteristic of video or film footage displayed possessing a sufficiently high frame rate (or field rate) that moving images do not blur or strobe even when tracked closely by the eye. The most common forms of high motion are NTSC and PAL video (i.e. “normal television”) at their native display rates. Movie film (at the standard 24 frame/s) does not portray high motion even when shown on television monitors.

Alternate use: In the context of digital video compression, “high motion” is sometimes used to describe footage in which frames change too rapidly for motion prediction techniques to be effective. This article describes only the high frame rate definition.
