In some cases, it is possible to see flicker at rates beyond 2000 Hz (2 kHz) in the case of high-speed eye movements (saccades) or object motion, via the "phantom array" effect. Fast-moving flickering objects zooming across view (either by object motion, or by eye motion such as rolling eyes), can cause a dotted or multicolored blur instead of a continuous blur, as if they were multiple objects. Stroboscopes are sometimes used to induce this effect intentionally.

A film is usually shot and projected at 24 still frames per second. The projector shutter breaks the light beam once as a new image is slid into place and once while it is held in place. Thus each frame is actually projected on the screen twice. This raises the number of flashes to the threshold of what is called "critical flicker fusion". curseforge gaming addons
