Second 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
- Translation: Artem Titarenko
- Verification: Stanislav Soldatov
Codecs that were tested
- 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
- During testing following metrics were measured:
- PSNR (Y, U, V, L, R, G, B components)
- SSIM (Y component)
- VQM (Y component)
- Blurring (Y, U, V components)
- Blocking (Y, U, V components)
- Two codec presets will be compared:
- “Maximum quality”
- “Balanced” (speed)
- Video sequences that were used in this comparison
- “foreman” (standard sequence)
- “susi” (standard sequence)
- “BBC” (standard sequence)
- “battle” (part from “Terminator-2” movie)
- “simpsons” (part from “The Simpsons” movie)
- “Matrix” (part from “The Matrix” movie)
- “Concert” (part from HDTV movie)
- Testing rules:
- Restrictions of codecs’ operation: only codecs that can work in Main profile of H.264 and do not use two passes were tested.
- Every codec was tested three times with separate speed measurements. After this median of these three values (middle value) was used as a resulting time.
- Following 10 bitrates were used for codec testing (Kbps): 100, 225, 340, 460, 700, 938, 1140, 1340, 1840, 2340.
- During testing three types of video sequences were used:
- Source sequences *.yuv in YUV 4:2:0 format.
- *.avi sequences in YUV 4:2:0 format with fourcc “YV12”.
- *.yuv sequences with duplicated last frame. These sequences were used for testing x264 codec.
- In this testing VirtualDub version 1.6.10 was used.
- In this testing AviSynth version 2.55 was used.
- For all metrics’ measurements in this test special build of MSU Video Quality Measurement Tool was used.
- For each preset both speed and quality were measured
- Total number of graphs in this comparison is 3796. Only 82 (2%) of them are in document;
- The number of computer-days is more than 20;
- Final document has 85 pages.

Automatic local color correction in S3D video
Stereo video may contain a huge color discrepancy. Most of the problems are hard to eliminate because of possible different distortions in each area in the frame.
