  High frame rates have been known to enhance the perceived visual quality of
specific video content. However, the lack of investigation of high frame rates
has restricted the expansion of this research field particularly in the context
of full-high-definition (FHD) and 4K ultra-high-definition video formats. This
study involves a subjective and objective quality assessment of compressed FHD
videos. First, we compress the FHD videos by employing high-efficiency video
coding, and VP9 at five quantization parameter levels for multiple frame rates,
i.e., 15fps, 30fps, and 60fps. The FHD videos are obtained from a high
frame-rate video database BVI-HFR, spanning various scenes, colors, and
motions, and are shown to be representative of the BBC broadcast content.
Second, a detailed subjective quality assessment of compressed videos for both
encoders and individual frame rates is conducted, resulting in subjective
measurements in the form of the differential mean opinion score reflecting the
quality of experience. In particular, the aim is to investigate the impact of
compression on the perceptual quality of compressed FHD videos and compare the
performance of both encoders for each frame rate. Finally, 11 state-of-the-art
objective quality assessment metrics are benchmarked using the subjective
measurements, to investigate the correlation as a statistical evaluation
between the two models in terms of correlation coefficients. A recommendation
for enhancing the quality estimation of full-reference (FR) video quality
measurements (VQMs) is presented after the extensive investigation.
