Perceptual quality of video with frame rate variation: A subjective study
This work investigates the impact of periodic frame rate variation on perceptual video quality. Among many dimensions of frame rate variation, as a first step we focus on videos in which two frame rates alternate over fixed intervals. We present subjective test results, and analyze the influence of several factors (including the average frame rate, the frame rate deviation, and the video content) on the perceptual quality.
