Frames Per Second (FPS) measures what aspect of video?

Frames Per Second (FPS) is a crucial measurement in video production that quantifies how many individual images, or frames, are shown in one second of video playback. The higher the FPS, the smoother the motion appears in the video. For instance, if a video runs at 30 FPS, that means 30 distinct frames are displayed in each second, contributing to a fluid motion and visual continuity essential for engaging video content. This measurement plays a significant role in various genres of video, particularly in action-driven sequences where motion clarity is paramount.

The other options do not accurately reflect the concept of FPS. The total number of colors displayed relates to color depth, the duration of each frame pertains more to frame timing, and the quality of the audio track is entirely unrelated to the video frame rate. Understanding FPS allows filmmakers and video producers to determine the right balance of motion smoothness and video style tailored to their project's needs.
