[Mp4-tech] MSU Subjective Comparison of Modern Video Codecs

[Dmitriy Vatolin]

Dear all!
We publish new (visual) comparison:
MSU SUBJECTIVE COMPARISON OF MODERN VIDEO CODECS
Goals of our assessment are subjective (visual) comparison of popular
videocodecs, comparison of results with objective metrics and subjective
assessment technology testing.
Main details:
    * 2 bitrates (690 kbps and 1024 kbps)
    * 4 tested codecs:
      + DivX 6.0
      + Xvid 1.1.0
      + x264 (open source H.264)
      + Microsoft WMV 9.0
    * 4 test sequences
    * 50 experts
    * Testing method SAMVIQ (see ITU-T BT.500)
Main comparison parts:
1. Subjective comparison of videocodecs.
2. Comparison of results with results of objective metrics PSNR, VQM and SSIM.
Good result for H.264 is that x264 has the same results on 690kbit as
Microsoft WMV 9.0 on 1024 kbit - really good job!
See details for DivX, XviD and comparison of metrics PSNR, VQM and SSIM
