Frame

A frame is a single still image in any sort of moving picture, many of which are shown in rapid succession to produce any given animation. In video games, frames are often used as a measurement of time. The length of a frame depends on the number of frames per second (FPS, sometimes referred to as "Hertz," a more general term for "Cycles per second") at which the game runs; since Melee is normally set to 60 FPS (50 in the PAL version of Melee), a frame is one sixtieth of a second (one fiftieth of a second for the PAL version). All events, actions and movements in Melee occur in increments of frames.
