BitRate <strong>HEVC</strong> compression About 50% compression over H264 for video resolutions of 1080p and above. 30-40% compression over H264 for lower resolutions MPEG-2 35% reduction in bitrate for same PSNR output when compared to H.264 H264/AVC Perceptual video quality is subjective and cannot be measured with PSNR values 1990 2000 2010 H265/<strong>HEVC</strong> Subjective tests have shown around 50% reduction in bitrate for similar perceptual video quality when compared to H.264
