About Annual MSU Video Codecs Comparisons

We perform comparative unbiased analysis for

  • software implementations
  • hardware (GPU-based) implementations
  • cloud-based implementations
of different video coding standards (H.265/HEVC, H.264/MPEG-4 AVC, AV1, VP9, VP8, MPEG-4 and other) using objective metrics (SSIM, VMAF, PSNR and other).

With MSU Codecs Comparison developers can verify the performance of their codec. We share test sequences, encoding parameters and codecs versions so all developers can reproduce the results of the comparison. Participation with publishing of all results is for FREE. Private participation is for fee (contact us for the details).

MSU codecs analysis team has been conducting video codec analysis, testing and optimization since 2004. Some facts about previous MSU Video Codecs Comparisons:
  • There were more than 400.000 downloads of previous H.264/MPEG-4 AVC and H.265/HEVC video codec comparisons reports
  • Many codecs' bugs were found and reported to developers
  • 210+ encoders were tested
  • More than 35 private reports for codec developers (description of codec's weak and strong points) after public report versions
Summary report topics:
  • Objective measurements
  • Subjective analysis
  • Encoding time
  • Speed/Quality trade-off analysis
  • Averaged objective results analysis
  • Leaders in different use cases

Comparison Rules and Methodology

2022 Comparison methodology in presentation

Please pay attention that we will use multi-core CPU for encoding, so you can use multi-threading
  • Decoding is performed with reference decoder (H.264/AVC, H.265/HEVC, VP9, AV1). For other standards participants should provide decoder
  • We don't limit GOP size and intra-period
  • We don't limit number of passes in the encoding. Total encoding time should fulfill use case speed requirements
Comparison Rules

Applying for participating, you agree with comparison rules.

Codec Requirements
  • Presets for different speed requirements should be provided by the developers
  • Codec should allow to set arbitrary bitrate of resulting stream in constant quality mode
  • Preferable codec interface - console codec version (with batch processing support - bitrate and file names must be possible to assign from the command line)
  • Encoder should be compatible with reference decoder, for encoders of custom standards a decoder should be provided
Developers Deliverables

The following deliverables should be provided by each developer:
  • Codec files (CLI executable file is preferable)
  • Codec's presets
Frequently asked questions (FAQ)

If you have any more questions about rules or methodology please refer to FAQ or contact us at

Take part in 2022 Video Codecs Comparison!

Deepest codecs review: 5 reports, including subjective with 1000+ viewers and 7000+ charts

Our pipeline of codecs testing:
  1. Prepare encoder. After your application, we send you instructions on how to prepare encoding presets for this year testing use cases (there are limitations for speed) and login for a submission system.
  2. Submission. You send us encoder and presets (our hardware characteristics can be found on the comparison page). Testing methodology is described in presentation.
  3. Speed and quality pre-check. We test the speed of your encoder. We let you know if some speedup is needed or any bugs are found. If the requirements are not satisfied, you submit an updated version and we test it again. Finally, when all requirements are satisfied, you confirm the usage of presets and encoder.
  4. Measurements. We perform the main measurements on this year test video set and prepare a draft of the report. This will take about 1-3 months depending on the number of participants.
  5. Draft report and verification. We send you a draft report with your results and the results of other public participants. You can double-check the results. If you participate privately, in this step you will need to decide whether you will publish your results.
  6. Report release. After your confirmation, we prepare and publish the final report on the comparison page. We send you the Enterprise version of the report (with all sequences, charts, etc.).
