Take part in 2020 MSU Video Codecs Comparison!

We perform comparative unbiased analysis for

  • software
  • hardware (GPU-based)
  • cloud-based (cloud transcoding)
implementations of different video coding standards (H.265/HEVC, H.264/MPEG-4 AVC, AV1, VP9, VP8, MPEG-4 and other) using objective metrics (SSIM, VMAF, PSNR and other) and massive subjective tests.

With MSU Video Codecs Comparison developers can verify the performance of their codec
We share test sequences, encoding parameters and encoder versions so all developers can reproduce the results of the comparison. Participation with publishing of all results is free. The comparison is done using encoding settings provided by the developers of each participating codec.

Comparison Methodology

Comparison methodology main points:
  • 100 FullHD video sequences (main report) + 10 4K video sequences (separate 4K comparison report).
  • SSIM, PSNR, VMAF objective metrics and subjective evaluation
  • 3 color-planes (Y,U,V) and integral metric values
  • 2 use-cases for comparison on FullHD videos: Fast and Offline encoding (differ by encoding speed) + 2 use-cases for subjective comparison on FullHD videos + 2 special use-cases for comparison on 4K videos
  • 8-10 different target bitrates (1-12 Mbps for HD and 2-20 Mbps for 4K)
  • Prosumer-level modern hardware
  • Fully automatic testing system
  • 15000+ resulting graphs, PDF and HTML reports
