Comparison Rules
4K codec testing objectives
The main goal of this report is the presentation of a comparative evaluation of the quality of new and existing codecs using objective measures of assessment. The comparison was done using settings provided by the developers of each codec. Nevertheless, we required all presets to satisfy minimum speed requirement on the particular use case. The main task of the comparison is to analyze different encoders for the task of transcoding video – e.g., compressing video for personal use.
Methodology update
We updated our methodology to improve fairness and objectivity in BSQ-rate calculation. The BSQ-rate compares the area under the quality-bitrate curve of a codec to that of a reference codec (Reference x265). This shows how much bitrate a codec can save while keeping the same visual quality. Previously, we calculated the area only over the intersection between each codec and the reference, which resulted in different denominators and gave an advantage to some codecs. This year, we fixed that by calculating the area over the intersection shared by all codecs.
Test Hardware Characteristics
- CPU: Intel Core i7 12700K (Alder Lake)
- SSD: 1Tb
- RAM: 4x16GB (64GB)
- OS: Ubuntu 22.04 LTS
For this platform we considered three key use cases with different speed requirements:
- Online – 4K@30fps
- VOD – 4K@5fps
- Offline – 4K@1fps

Final video set consists of 15 sequences including new videos from Vimeo and media.xiph.org derf's collection.
Descriptions of all test videos are presented in a separate PDF provided with the report.
Codec Analysis and Tuning for Codec Developers and Codec Users
Computer Graphics and Multimedia Laboratory of Moscow State University:
- 20+ years working in the area of video codec analysis and tuning using objective quality metrics and subjective comparisons.
- 30+ reports of video codec comparisons and analysis (H.265, H.264, AV1, VP9, MPEG-4, MPEG-2, decoders' error recovery).
- Methods and algorithms for codec comparison and analysis development, separate codec's features and codec's options analysis.
Strong and Weak Points of Your Codec
- Deep encoder parts analysis (ME, RC on GOP, mode decision, etc).
- Weak and strong points for your encoder and complete information about encoding quality on different content types.
- Encoding Quality improvement by the pre and post filtering (including technologies licensing).
Independent Codec Estimation Comparing to Other Codecs for Different Use-cases
- Comparative analysis of your encoder and other encoders.
- We have direct contact with many codec developers.
- You will know place of your encoder between other newest well-known encoders (compare encoding quality, speed, bitrate handling, etc.).
Encoder Features Implementation Optimality Analysis
We perform encoder features effectiveness (speed/quality trade-off) analysis that could lead up to 30% increase in the speed/quality characteristics of your codec. We can help you to tune your codec and find best encoding parameters.Thanks
