MSU HEVC/AV1 Video Codecs Comparison 2019
MSU Video-Codec Comparison 2019 FullHD and Subjective reports are released http://compression.ru/video/codec_comparison/hevc_2019/
Free versions of the reports are available from direct links (FullHD and Subjective). If someone is interested in the enterprise version, you can get it with 20% discount before 30/11/19 (use this link or a promo HEVC-NOVEMBER-2019-DN) This year we used 100 videos for our tests (list of videos and descriptions: http://compression.ru/video/codec_co...19/videos.html) The winners in objective comparison are: HW265 (Huawei) by SSIM Tencent V265 Encoder by VMAF Best bitrate handling: x264 in fast encoding use-case, HW265 in universal and ripping encoding use-cases Most often was Pareto-optimal: HW265 in fast encoding use-case, Tencent V265 Encoder in universal, SIF and x264 in ripping use-case. Results of subjective comparison: Soon the comparison of cloud transcoding services will be released, and also we will perform 4K and high-quality (including AV1) comparisons this year. Any feedback is very welcome!

You can find the description in the PDF of Subjective report 2019
Also, last year we described study method in a separate PDF (2018 subjective study method). This year the methodology was the same, with one difference that the participants of FullHD comparison could use another codec binary and presets for subjective comparison. Some questions are considered on subjectify.us website. If there are other questions, we can discuss them here

I couldn't find out from the PDF since it doesn't have the command lines used. But, x264/x265 need different 'tune' for optimizing for PSNR, SSIM or for subjective tests. Were different versions created for the metrics-based tests and for the subjective tests? And if not, what were the settings tuned for?
