Input lag or input latency is the amount of time that passes between sending an electrical signal and the occurrence of a corresponding action.. In video games the term is often used to describe any latency between input and the game engine, monitor, or any other part of the signal chain reacting to that input, though all contributions of input lag are cumulative.
At 24 FPS, the film travels through the projector at a rate of 456 millimetres (18.0 in) per second. This allowed simple two-blade shutters to give a projected series of images at 48 per second, satisfying Edison's recommendation. Many modern 35 mm film projectors use three-blade shutters to give 72 images per second—each frame is flashed on ...
In early cinema history, there was no standard frame rate established. Thomas Edison's early films were shot at 40 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.
The main speed measurement metric is frames per second (FPS) - how many frames deinterlacer is able to process per second. Talking about FPS, it is necessary to specify the resolution of all frames and hardware characteristics, because the speed of specific deinterlacing method significantly depends on these two factors.
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 ...
Choppiness can also occur if the rendering rate is not the same as the monitor's frame rate. For example, assume the video card is redrawing a scene depicting a smoothly moving object 65 times per second, and the monitor's refresh rate is 60Hz. Every 13th frame will be dropped, resulting in the object appearing to jerk forward 5 times per second.
A Phase Alternating Line (PAL)-based television set display, for example, scans 50 fields every second (25 odd and 25 even). The two sets of 25 fields work together to create a full frame every 1/25 of a second (or 25 frames per second), but with interlacing create a new half frame every 1/50 of a second (or 50 fields per second).

With doubled temporal resolution, 576p50 is considered enhanced-definition television (), regardless of the image being scaled the same way as an interlaced frame.In some countries, such as Australia, the 576p resolution standard is technically considered high-definition [10] [11] and was in use by the Special Broadcasting Service (SBS TV), eventually replaced by 720p for its high-definition ...
