This project deals with objective comparison of video codecs, mostly of H.264 standard.
In 2005-2006 two comparsons of video codecs were conducted by our lab. In the first comparison we compared the following codecs:

  • Mpegable AVC Codec
  • Moonlight H.264 Video Codec
  • MainConcept H.264 Codec
  • Fraunhofer IIS Codec
  • Ateme MPEG-4 AVC / H.264 Codec
  • Videosoft H.264 Codec
  • DivX Pro 5.1.1 Codec (NOT 264! Used for comparison with H.264 codecs as well tuned codec from previous generation MPEG-4 ASP)

Following codecs took part in the second comparison:

  • DivX 6.0 (Not H.264 video codec, tested as reference codec)
  • ArcSoft H.264
  • Ateme H.264
  • ATI H.264
  • Elecard H.264
  • Fraunhofer IIS H.264
  • VSS H.264
  • x264

Codecs were compared using PSNR - most commonly accepted objective metric. In addition, VQM and SSIM were used in the second comparison. In second comparison tho presets of codecs were evaluated: "Maximum quality" and "Balanced" (more speed oriented). Full aqnalysis and results can be found in PDF with the comparisons.
