What term describes the number of frames displayed per second in video?

• A. Frame Rate
• B. Cinematic Frame Rate
• C. Video Compression
• D. Codec

Answer: (A)

The rate at which frames are displayed per second is called the frame rate. It tells you how many individual frames the video shows each second, and this directly affects how smooth the motion looks—more frames per second means smoother motion, while fewer frames can look choppier. Common examples are film-style 24 frames per second, standard video around 30 frames per second, and higher 60 frames per second for very smooth movement. The other terms don’t describe how fast frames are shown: cinematic frame rate isn’t a standard technical term, and video compression and the codec deal with reducing data size and how the video is encoded/decoded, not the speed of frame playback.
