motion artifact

AKA: Strobing, Nyquist LimitThe 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.

Shots of objects that quickly move in the camera s frame, and/or shots with a slow shutter speed are likely to produce a smearing effect, since the object is in a range of positions during a single exposure.

Motion Detection helps you produce sharper results by automatically selecting a faster shutter speed and higher ISO (light sensitivity) setting to compensate for subject movement or camera shake.
