What is the standard frame rate for film?

• A. 30 fps
• B. 60 fps
• C. 12 fps
• D. 24 fps

Answer: (D)

Frame rate in cinema is the speed at which individual frames are shown each second, and it shapes how motion appears on screen as well as how efficiently film stock is used. The standard for traditional cinema is 24 frames per second. This speed provides a smooth enough portrayal of motion to feel natural to the eye, while also keeping film stock costs reasonable for feature-length productions. It also fits with the way sound-on-film systems were designed, so audio could be synchronized reliably without needing a faster rate. The result is the familiar cinematic look and workflow that audiences associate with movies.

Other rates don’t fit the traditional cinema workflow: 30 frames per second is common in television and some video formats, but not the established cinema standard; 60 frames per second is used in some modern high-frame-rate video projects and certain productions, but it changes the characteristic motion feel of film; 12 frames per second would look noticeably choppy and is far below what audiences expect from cinema. So 24 frames per second is the conventional standard for film.
