High frame rate

In motion picture technology—either film or video—high frame rate (HFR) refers to higher frame rates than typical prior practice.

The frame rate for motion picture film cameras was typically 24 frames per second with multiple shuttering on each frame to prevent flicker during projection. Television video historically operated at 50 or 60 images per second using interlaced scanning. (A video "frame" is actually two images, hence PAL 25fps looks nothing like film's 24fps.) Frame rates higher than 24 Hz for feature motion pictures and frame rates higher than 30 Hz for other applications is an emerging trend in the 21st century.

History of frame rates in cinema

In early cinema history, there was no standard frame rate established. Edison's early films were shot at 40 frames per second (fps), while the Lumière Brothers used 16 fps. This had to do with a combination of the use of a hand crank rather than a motor, which created variable frame rates because of the inconsistency of the cranking of the film through the camera. After the introduction of synch sound recording, 24 fps became the industry standard frame rate for capture and projection of motion pictures. 24 fps was chosen because it was the best frame rate for sound clarity – lower frame rates produced sound tracks with too much surface noise.
