Third Annual MSU MPEG-4 AVC/H.264 Video Codec Comparison
For people, who make real research in field of high-end video compression and professionally use videocodecs
- Project head: Dr. Dmitriy Vatolin
- Testing, charts, analysis: Dmitriy Kulikov, Alexander Parshin
- Translating: Artem Titarenko
- Verification: Dr. Maxim Smirnov
Codecs that Were Tested
- DivX 6.2.5 (Is not H.264 codec, was taken only as reference)
- MainConcept H.264
- Intel H.264
- VSS H.264
- Apple H.264 (partial tested)
- Sorenson H.264 (partial tested)
There are two parts of the comparison - 2006 year results and over-years comparison. First part is comparison of modern codecs, provided by developers in this year. Second part is summarizing of H.264 codecs results over three previous years.
Following metrics were measured:
- PSNR (Y, U, V components)
- SSIM (Y component)
- VQM (Y component)
Codecs were analyzed separately in the following types of application:
Individual codecs’ settings were used for each of that types of application.
Video sequences that were used in this comparison:
- “foreman” (standard sequence)
- “akiyo” (standard sequence)
- “carphone” (standard sequence)
- “battle” (part from “Terminator-2” movie)
- “rancho” (part from “Terminator-2” movie)
- “matrix” (part from “The Matrix” movie)
- “futurama” (part from “Futurama” cartoon)
- “concert” (part of HDTV translation)
Different Comparion Versions
Short version of report is now available at website for free download (52 pages, 47 figures). Full version of report now available for free download too (157 pages, 185 charts). It includes following additional topics:
- SSIM RD curves individually for each sequence from all sequences
- All codecs presets
- Differences between PSNR and SSIM results
- Absolute encoding speed charts
- Relative Bitrate/Relative Speed graphs individually for each sequence from test set
- Relative bitrate for the same quality for all pairs of codecs
- Bitrate handling graphs
- Per-frame quality and dispersion graphs
- Additional results for Apple and Sorenson codecs
- More detailed testing results for DivX 6.2.5 codec (most presets of this codec)
- All sequences, used in this comparison are provided with full version of report.
All codec’s options and presets were provided by codec’s authors
An important restriction on a preset is encoding time for it. A few iterations of compliance testing and preset optimization were made to meet the requirements.
JM 9.8 reference decoder was used to decode all encoded streams.
All objective metrics measurements were performed with MSU Video Quality Measurement Tool (Pro Version)
For each preset both speed and quality were measured
Dear video codec professionals!

This contribution will help us:
- To continue this comparison without any participation fees (this is important for x264 and XviD AVC next year)
- To avoid comparison sponsorship by codecs’ developers
- To keep comparison detailed and useful
Thank you for your contribution in advance!
