What does Frames Per Second (FPS) measure?

Frames Per Second (FPS) specifically measures the playback speed of an animation or video. It indicates how many individual frames or images are displayed in one second of video playback. A higher FPS value means smoother motion, which is crucial for animations and videos, as it provides a more fluid and realistic visual experience. For example, a standard cinema film typically runs at 24 FPS, while video games may run at 30, 60, or even higher FPS to ensure seamless movement and responsiveness.

In contrast, the other options do not relate to how FPS is defined: sound quality pertains to audio characteristics unrelated to FPS; data transmission speed refers to the rate at which data is sent or received over a network; and the amount of data stored in a file deals with file size, not frame rate.
