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
