Over the last years, we have seen exciting improvements in video compression technology, due to the introduction of HEVC and royalty-free coding specifications such as VP9. [] Key Result BD-rate calculations show that using x265 and libvpx vs. x264 can lead to significant bitrate savings for the same quality. x265 outperforms libvpx in most cases, but the performance gap narrows (or even reverses) at the higher resolutions.

Compression Performance Comparison of x264, x265, libvpx and aomenc for On-Demand Adaptive Streaming Applications

Evaluation of the performance of these compression standards x264, x265, libvpx and aomenc all achieve substantial compression efficiency improvement over x264 reveals.

A comparative performance evaluation of VP9, x265, SVT-AV1, VVC codecs leveraging the VMAF perceptual quality metric

VVC achieved the best video coding performance, significantly outperforming all other codecs, and AV1 consistently outperformed x265, but with narrow margins in some video sequences, suggesting that a cautious selection between the two codecs needs to based on application-specific criteria.

A Comprehensive Video Codec Comparison

This paper compares the video codecs AV1, HEVC, AVC, JEM, and the VVC under two fair and balanced configurations: All Intra for the assessment of intra coding and Maximum Coding Efficiency with all codecs being tuned for their best coding efficiency settings.

Performance comparison of AV1, HEVC, and JVET video codecs on 360 (spherical) video

This paper compares the coding efficiency performance on 360 videos, of three software codecs: AV1 video codec from the Alliance for Open Media (AOM); (b) the HEVC Reference Software HM; and (c) the JVET JEM Reference SW, and concludes that under constant quality coding, AV1 underperforms HEVC, whichunderperforms JVet.

Video codec comparison using the dynamic optimizer framework

A new methodology that allows for more objective comparison of video codecs, using the recently published Dynamic Optimizer framework, is presented, which offers the possibility to do visual perceptual optimization of any video codec and thus produce optimal results in terms of PSNR and VMAF.

User Generated HDR Gaming Video Streaming: Dataset, Codec Comparison, and Challenges

The results show that the latest compression standard AV1 results in the best compression efficiency, followed by HEVC, H.264, and VP9, on 10-bit, UHD-HDR content gaming content.

Adaptive Encoding for Constrained Video Delivery in HEVC, VP9, AV1 and VVC Compression Standards and Adaptation to Video Content

The results demonstrate that the optimal encoding parameters obtained from the Pareto front space can provide significant bandwidth savings without sacrificing quality.

A Comparison of JEM and AV1 with HEVC: Coding Tools, Coding Efficiency and Complexity

It is found that JEM considerably outperforms HM and AV1 in terms of coding efficiency while AV1 cannot transform increased complexity into competitiveness in termsOf coding efficiency with neither of the competitors except for the all-intra configuration.
