An animated segment of a film promoting the 2012 Summer Olympics was blamed for triggering seizures in people with photosensitive epilepsy. The charity Epilepsy Action received telephone calls from people who had seizures after watching the film on television and online. In response, the London 2012 Olympic Committee removed the offending ...
As users adjust to the experience, they see increasingly complex animated yantra-like patterns of color behind their closed eyelids (similar effects may be seen when travelling as a passenger in a car or bus; close your eyes as the vehicle passes through the flickering shadows cast by regularly spaced roadside trees, streetlights or tunnel ...
Temporal light artefacts (TLAs) are undesired effects in the visual perception of a human observer induced by temporal light modulations. Two well-known examples of such unwanted effects are flicker and stroboscopic effect. Flicker is a directly visible light modulation at relatively low frequencies (< 80 Hz) and small intensity modulation levels.
If the modulation frequency is below the flicker fusion threshold and if the magnitude of the TLM exceeds a certain level, then such TLMs are perceived as flicker. Light modulations with modulation frequencies beyond the flicker fusion threshold are not directly perceived, but illusions in the form of stroboscopic effect may become visible ...
Boris RED is an integrated 3D compositing, titling, and effects application that works with the Adobe Creative Suite, Avid, Apple, Grass Valley, Media 100 and Sony editing systems. RED adds features to NLE timelines and integrates a standalone engine for effects creation and rendering.
The flicker fusion threshold, also known as critical flicker frequency or flicker fusion rate, is the frequency at which a flickering light appears steady to the average human observer. It is a concept studied in vision science , more specifically in the psychophysics of visual perception .
Bloom (sometimes referred to as light bloom or glow) is a computer graphics effect used in video games, demos, and high-dynamic-range rendering (HDRR) to reproduce an imaging artifact of real-world cameras. The effect produces fringes (or feathers) of light extending from the borders of bright areas in an image, contributing to the illusion of ...
Adobe After Effects is a digital visual effects, motion graphics, and compositing application developed by Adobe Inc.; it is used for animation and in the post-production process of film making, video games and television production. Among other things, After Effects can be used for keying, tracking, compositing, and animation.
