What Is Frame Rate?

In motion pictures, television, and in computer video displays, the frame rate is the number of unique consecutive frames or images that are projected or displayed per second. Frame rate is measured in frames per second (fps). The more frames recorded per second, the more accurately motion is documented onto the recording medium.

Early television systems selected frame rates based on local electrical standards to avoid electrical interference with the picture. NTSC in North America uses 30 fps (now adjusted to 29.97 fps for color NTSC) based on 60 Hz electrical power. PAL, used primarily in Europe, uses 25 fps based on 50 Hz electrical mains.

The standard film cameras projection speed is 24 fps. When playing movies on NTSC television, it needs a process named telecine or pulldown to convert 24 fps movie to 29.97.

For computer video files, any frame rate will be OK. Lower frame rate consumes less disk space, but looks jerky. Higher frame rate consumes more disk space, but looks more smooth. For general videos, 24 fps is enough. Video surveillance and video conference usually use lower fps. Some 3D video use double fps to alternately display two images for two eyes.

Brief Introduction on Different Frame Rate

There are three main frame rate standards in the TV and digital cinema business: 24p, 25p, and 30p.

  • 24p is a progressive format and is now widely adopted by those planning on transferring a video signal to film.
  • 25p is a progressive format and runs 25 progressive frames per second.
  • 30p is a progressive format and produces video at 30 frames per second. Progressive (noninterlaced) scanning mimics a film camera's frame-by-frame image capture.

However, there are many variations on these as well as newer emerging standards like 50i/p, 60i/p, 72p, 120p, 300p and etc.
