In this paper, we conducted a comprehensive survey of the effects of different frame rates (FRs) on human performance and reviewed more than 50 studies and summarized them in the areas of psychomotor performance, perceptual performance, behavioral effects, and subjective perception. Overall, there seems to be strong support for a threshold of around 15 Hz for many tasks, including those that are psychomotor and perceptual in nature. Less impressive yet acceptable performance may be accomplished at around 10 Hz for many tasks. Subjective reactions to the quality and watchability of videos seem to support rates of 5 Hz, although videos presented at 15 Hz and above are generally more widely preferred. These generalizations regarding superior and acceptable FRs may also be subject to the effects of several moderating factors such as display characteristics, nature of the tasks, viewing condition, additional cues, and user experience.
