Frame rate
The temporal sensitivity and resolution of human vision varies depending on the type and characteristics of visual stimulus, and it differs between individuals.[2] Modulated light (such as a computer display) is perceived as stable by the majority of participants in studies when the rate is higher than 50 Hz.Projectionists could also change the frame rate in the theater by adjusting a rheostat controlling the voltage powering the film-carrying mechanism in the projector.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 screen three times.However, when a character is required to perform a quick movement, it is usually necessary to revert to animating "on ones", as "twos" are too slow to convey the motion adequately.A resolution of 1080i produces 59.94 or 50 1920×540 images, each squashed to half-height in the photographic process and stretched back to fill the screen on playback in a television set.[21] High frame rates make action scenes look less blurry, such as sprinting through the wilderness in an open world game, spinning rapidly to face an opponent in a first-person shooter, or keeping track of details during an intense fight in a multiplayer online battle arena.To mitigate the choppiness of poorly optimized games, players can set frame rate caps closer to their 99% percentile.A low frame rate causes aliasing, yields abrupt motion artifacts, and degrades the video quality.Pixel hallucination-based methods use deformable convolution to the center frame generator by replacing optical flows with offset vectors.
