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
