Investigating the Impact of High Frame Rate on Video Quality: A SAMVIQ Approach

High Frame Rate (HFR) aims at increasing the perceived video quality by decreasing motion artifacts and enabling a smoother playback of movements. However, HFR is not yet widely used in video playback, as most movies are partly due to artistic reasons still shot and shown at 24 frames per second (fps) and streamed videos are usually capped at 60 fps. This raises the question of whether people can perceive differences with higher frame rates and a connected increase in quality at all. To this effect, this paper analyzes the relationship between frame rate and perceived video quality using the Subjective Assessment Methodology for Video Quality (SAMVIQ). In the test, 24 subjects assessed the video quality of 16 sources with varied frame rates. The results show an increased video quality for videos with higher frame up to 120 fps. The SAMVIQ methodology is useful and our version is made publicly available.
