Frame rate, most commonly expressed in frame/s, frames per second or FPS, is typically the frequency (rate) at which consecutive images are captured or displayed. This definition applies to film and video cameras , computer animation , and motion capture systems.
Only films with a native (without motion interpolation) shooting and projection frame rate of 48 or higher, for all or some of its scenes, are included, as are films that received an official post-conversion using technologies such as TrueCut Motion. This is at least double the 24 frames per second (fps) standard used in Hollywood. [1]
The exact rate is 60000/1001, which works out to be slightly over 59.94 frames per second. 60p is a progressive format that is very close to the 60000/1001 broadcast system used in some countries. In the Broadcast industry it is sometimes but not always used as shorthand for 60000/1001 frames per second. [ 17 ]
At rates below 12 frames per second, most people can detect jerkiness associated with the drawing of new images that detracts from the illusion of realistic movement. [2] Conventional hand-drawn cartoon animation often uses 15 frames per second in order to save on the number of drawings needed, but this is usually accepted because of the ...
The TV is natively only capable of displaying 120 frames per second, and basic motion interpolation which inserts between 1 and 4 new frames between existing ones. Typically the only difference from a "120 Hz" TV in this case is the addition of a strobing backlight , which flickers on and off at 240 Hz, once after every 120 Hz frame.
For a fixed bandwidth, interlace provides a video signal with twice the display refresh rate for a given line count (versus progressive scan video at a similar frame rate—for instance 1080i at 60 half-frames per second, vs. 1080p at 30 full frames per second). The higher refresh rate improves the appearance of an object in motion, because it ...
The field rate of analog television and video systems was typically 50 or 60 fields per second. Usage of frame rates higher than 24 fps for feature motion pictures and higher than 30 fps for other applications are emerging trends.
This is because the "30 frame/s" frame rate of NTSC is actually 30/100.1%, also referred to as 29.97 frame/s – this frame rate is matched when video at 23.976 frame/s has a 3:2 pulldown applied. Similarly, 60i is shorthand for 60/100.1% fields per second. Some NLE programs may refer to 23.976 as 23.98, causing a small amount of confusion.
