Rubix StudiosRubix StudiosFrame rate refers to the number of individual frames or images displayed per second in a video. It is measured in frames per second (fps). Common frame rates include 24 fps for cinema, 30 fps for broadcast television, and 60 fps for smoother motion often used in gaming or sports.
Frame rate determines how motion is perceived. Lower frame rates create a more cinematic look with slight motion blur, while higher frame rates capture more detail and fluidity, making movement appear smoother and more lifelike.

Frame rate affects not only aesthetics but also technical aspects such as file size, bandwidth, and playback compatibility. Higher frame rates demand more storage and processing power but allow slow-motion playback when footage is interpreted at a lower frame rate.
Professional productions use variable frame rates for different creative goals. For example, 24 fps may be used for narrative film, 120 fps for slow motion in sports replays, and 48 fps or higher for experimental formats. The choice of frame rate is also tied to shutter speed, often set using the 180-degree shutter rule for natural motion.

Example
A filmmaker records at 24 fps to achieve a traditional cinematic look for a drama. For an action sequence, a second camera records at 120 fps. In editing, the footage is slowed down to create smooth slow-motion highlights, adding dramatic impact to the scene.
