FPS is the standard abbreviation for Frames Per Second, the measurement of how many individual still images are displayed sequentially per second to create the illusion of motion in video content. It is one of the most fundamental technical specifications in video production, determining both the smoothness of motion and the temporal aesthetic of the footage.

Common frame rates include 24 FPS, the cinematic standard that produces the characteristic motion blur and temporal feel of theatrical film; 30 FPS, the broadcast television standard in NTSC regions; 60 FPS, used for smooth sports coverage and modern gaming content; and higher frame rates like 120 FPS or 240 FPS used for slow-motion capture. The choice of frame rate has profound implications for how motion is perceived, with lower frame rates creating a more stylized, cinematic feel and higher frame rates producing smoother, more fluid motion that can appear hyperreal or video-like.

In AI video generation, frame rate is typically a technical parameter set during generation or export, affecting both the smoothness of motion and the computational cost of producing the footage. Understanding FPS helps creators make informed decisions about the temporal characteristics of their generated content and ensures compatibility with delivery platforms that have specific frame rate requirements.
