* - YUV-VMAF was calculated as VMAF for all colour-planes (Y, U, V) following the same methodology as YUV-SSIM, YUV-PSNR and other metrics.

The biggest number of codecs took part in comparison of Slow encoding (1 fps). The winners vary for different objective quality metrics. The participants were rated using BSQ-rate (enhanced BD-rate) scores [1].

Comparison Rules


4K codec testing objectives

The main goal of this report it the presentation of a comparative evaluation of the quality of new HEVC codecs and codecs of other standards using objective measures of assessment. The comparison was done using settings provided by the developers of each codec. Nevertheless, we required all presets to satisfy minimum speed requirement on the particular use case.

Test Hardware Characteristics

  • CPU: Intel Socket 1151 Core i7 8700K (Coffee Lake) (3.7Ghz, 6C12T, TDP 95W)
  • Mainboard: ASRock Z370M Pro4
  • RAM: Crucial CT16G4DFD824A 2x16GB (totally 32 GB) DIMM DDR4 2400MHz CL15
  • OS: Windows 10 x64, Linux (Ubuntu 20.4)

For this platform we considered four key use cases with different speed requirements:

  • Fast 8-bit: UHD, 30fps
  • Slow 8-bit: UHD, 1fps
  • Fast 10-bit: UHD-10bit, 30fps
  • Slow 10-bit: UHD-10bit, 1fps

See more on Call For Codecs 2021 page

25 video sequences at 4K resolution were used for tests: 18 video sequences had 8-bit color depth and 7 video sequences had 10-bit color depth. Note: we used technically 10-bit videos for evaluation, but the colours in the videos themselves do not utilize wide luminance range (they are not HDR).


Codec Analysis and Tuning for Codec Developers and Codec Users


Computer Graphics and Multimedia Laboratory of Moscow State University:

  • 17+ years working in the area of video codec analysis and tuning using objective quality metrics and subjective comparisons.
  • 30+ reports of video codec comparisons and analysis (H.265, H.264, AV1, VP9, MPEG-4, MPEG-2, decoders' error recovery).
  • Methods and algorithms for codec comparison and analysis development, separate codec's features and codec's options analysis.

Strong and Weak Points of Your Codec

  • Deep encoder parts analysis (ME, RC on GOP, mode decision, etc).
  • Weak and strong points for your encoder and complete information about encoding quality on different content types.
  • Encoding Quality improvement by the pre and post filtering (including technologies licensing).

Independent Codec Estimation Comparing to Other Codecs for Different Use-cases

  • Comparative analysis of your encoder and other encoders.
  • We have direct contact with many codec developers.
  • You will know place of your encoder between other newest well-known encoders (compare encoding quality, speed, bitrate handling, etc.).

Encoder Features Implementation Optimality Analysis

We perform encoder features effectiveness (speed/quality trade-off) analysis that could lead up to 30% increase in the speed/quality characteristics of your codec. We can help you to tune your codec and find best encoding parameters.
