That may not seem like much, but a single frame of video may have hundreds of thousands of pixels in it, and so if we combine all of the tiny motions that we see from across that entire image, then suddenly a thousandth of a pixel can start to add up to something pretty significant.
Poate nu pare mare lucru, dar un singur cadru al filmului poate conţine sute de mii de pixeli şi dacă am combina toate mişcările alea minuscule din întreaga imagine, miimile de pixel se pot aduna,  rezultând ceva destul de semnificativ.
