"30 frames per second" (30 FPS) refers to the rate at which consecutive images, or frames, are displayed in a video. This means that every second, 30 individual images are shown to create the illusion of smooth motion. This frame rate is commonly used in television broadcasts and online videos, providing a balance between smooth visuals and manageable file sizes. In comparison to higher frame rates, such as 60 FPS, 30 FPS may appear less fluid, especially during fast-moving scenes. However, it is often sufficient for many types of content, including movies and video games, where a cinematic feel is desired without overwhelming the viewer.
