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.
Note that with 23.976 fps time code, the "second" counter is still increased after 24 frames, even though 24 frames add up to slightly more than a real second. When working with other time sources, confusion can arise since a "second" in 23.976 fps time code notation is slightly longer than a real second, it is 1.001 (24 × 1 / (24000 / 1001 ...
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 (fps) with multiple flashes on each frame during projection to prevent flicker.
25i, also known as 50i, is an interlaced format showing 25 interlaced frames per second, or 50 fields per second, and is the standard broadcast framerate for countries with a PAL and SECAM television history (most of the world). The interlaced format sacrifices some detail in vertical resolution in favor of a higher apparent framerate, and can ...
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]
A high-speed camera is a device capable of capturing moving images with exposures of less than 1 / 1 000 second or frame rates in excess of 250 frames per second. [1] It is used for recording fast-moving objects as photographic images onto a storage medium. After recording, the images stored on the medium can be played back in slow motion.
Muybridge's photographic sequence of a race horse galloping, first published in 1878. High-speed photography is the science of taking pictures of very fast phenomena. In 1948, the Society of Motion Picture and Television Engineers (SMPTE) defined high-speed photography as any set of photographs captured by a camera capable of 69 frames per second or greater, and of at least three consecutive ...
In the early 20th century when 35mm movie film was developed, producers found that 18–24 frames per second was adequate for portraying motion in a movie theater environment. Flicker was still a problem at these rates, but projectors solved this by projecting each frame twice, thus creating a refresh rate of 36–48 Hz without using excessive ...
