  2. Frame rate - Wikipedia

    en.wikipedia.org/wiki/Frame_rate

    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 ...

  3. Input lag - Wikipedia

    en.wikipedia.org/wiki/Input_lag

    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.

  4. High frame rate - Wikipedia

    en.wikipedia.org/wiki/High_frame_rate

    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.

  5. Micro stuttering - Wikipedia

    en.wikipedia.org/wiki/Micro_stuttering

    Assuming a 60 Hz refresh rate, a benchmark tool may report this as 144 frames per second. However, the user will perceive less due to some frames existing for a tiny fraction of a display's refresh cycle. Micro stuttering is a quality defect that manifests as irregular delays between frames rendered by a graphics processing unit (GPU).

  6. Deinterlacing - Wikipedia

    en.wikipedia.org/wiki/Deinterlacing

    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.

  9. Interlaced video - Wikipedia

    en.wikipedia.org/wiki/Interlaced_video

    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).
