Television is 30 FPS [Frames Per Second], but generally not desirable for film making. Cinematographers prefer the movie film image quality of 24 FPS. With the advent of HDTV [High Definition Television] at 60 FPS, there is a need for digital cameras to have HDTV image density with “film-like” imagery. 24 FPS is used to convince the brain of motion. Cranking is the term used by cinematographers to turn the “crank” to move the film in the camera. Undercranking increases the speed of the image. Overcranking is used to create a slow-motion effect. Other speeds are used for special effects.
