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
  • x264

  • Comparison content

  • 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

  • Comparison statistic

  • 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.
