“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 25 or 30 frames per second using interlaced scanning until the advent of the 720p HDTV format using 50 or 60 frames per second. 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.” http://en.wikipedia.org/wiki/High_frame_rate
Ever wonder what it would be like to be able to control time?
