So if a video is captured and played back at 24fps, that means each second of video shows 24 distinct still images. It’s usually expressed as “frames per second,” or FPS.

Each of those images is called a “frame.”įrame rate, then, is the speed at which those images are shown, or how fast you “flip” through the book. Whether digital or old-school film, video is a series of still images that, when viewed in order at a certain speed, give the appearance of motion.
