Framerate refers to the number of frames or images that are displayed per second in a video. It is measured in terms of frames per second (fps) and indicates how smoothly an animation, movie or video game will appear on screen. A higher framerate means smoother motion and less choppiness while a lower framerate can result in jerky movement and a lack of fluidity. The ideal framerate for a video depends on the content being displayed but generally ranges from 24 to 60 fps, with most movies being filmed at 24fps and high-action scenes requiring higher frame rates to maintain smooth motion.
