Comparison Methodology

Comparison methodology main points:
  • 50 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, automatic testing system
  • 15000+ resulting graphs, PDF and HTML reports
