fps / FPS
(1) (pronounced as separate letters) Short for frames per second (and typically written in lower case), a measure of how much information is used to store and display motion video. The term applies equally to film video and digital video. Each frame is a still image; displaying frames in quick succession creates the illusion of motion. The more frames per second (fps), the smoother the motion appears. Television in the U.S., for example, is based on the NTSC format, which displays 30 interlaced frames per second (60 fields per second). In general, the minimum fps needed to avoid jerky motion is about 30. Some computer video formats, such as AVI, provide only 15 frames per second.
(2) Capitalized, FPS is short for first-person shooter, a game genre. FPS games are ones that are in the first-person perspective where the gamer can only see the character's hands holding a weapon on the screen.
