Moscow State University Graphics & Multimedia Laboratory has finished 6-th H.264 codecs comparison.
It is intended for practical researchers and developers in the field of high-end video compression.

We have tested newest implementations of MPEG-4 AVC/H.264 video codecs and compare with XviD (MPEG-4 ASP) and Theora encoders.
One of the main targets for this comparison was to test H.264 encoders for transcoding tasks for Movies and HDTV video content.

Codec that were tested:

  • DivX H.264
  • Elecard H.264
  • Intel® MediaSDK AVC/H.264
  • MainConcept H.264
  • Microsoft Expression Encoder
  • Theora
  • x264
  • XviD (MPEG-4 ASP codec)
  • VP8

Summary report topics:

  • Objective measurements (SSIM, PSNR, Average Advantage and etc.)
  • Encoding speed
  • Analysis of averaged objective results
  • Leaders in different areas (Movies, HDTV)
  • Options analysis for codecs
  • Additional subjective analysis for video codes
    • For psycho-visual enhancement in codecs analysis
    • For fade processing analysis
    • For animation movie compression analysis
  • Codecs encoding quality progress over years

Enhancements in comparison to Previous H.264/AVC Comparison:

  • Subjective comparison
  • New codecs
  • New sequences
  • New type of special analysis for codecs
  • Using natural sequences’ special modifications
  • Using synthetic sequences
  • Not only H.264 Codecs (but also XviD, Theora) were tested
