English thesaurus
motion artifact
cinema
The visual interference patterns between a shot's frame rate and a filmed object's periodic motion or change. If a shot is filmed with a frame rate R, any images of periodic events of a frequency greater than R/2
the "Nyquist Limit"
will be misrepresented on film. A commonly-occuring example of this artifact is the illusion of spoked wheels appearing to turn in the wrong direction or at the wrong rate. Incorrect frame rates and synchronization can also cause strobing during shots of projected movies or of television screens. See also artifact, judder.
