Performance Assessment of AV1, x265 and VVenC Open-Source Encoder Implementations Compared to VVC and HEVC Reference Software Models

Video applications continue to gain a lot of traction and have an enormous demand. As a result, there is a strong demand to decrease the video transmission bitrate without reducing visual quality [1],[2]. The efforts to achieve bitrate savings, especially for high-definition video content started in 2010, when the ITU-T Video Coding Experts Group (VCEG) and ISO/IEC Moving Pictures Expert Group (MPEG) established a Joint Collaborative Team on Video Coding (JCT-VC) to work on the High-Efficiency Video Coding (HEVC) standard. Then, in 2013, the 1st version of the HEVC specification was approved by ITU-T as Recommendation H.265 and by ISO/IEC as MPEG-H, Part 2 [3]. When developing the H.265/MPEG-HEVC standard, high-resolution and high frame-rate video coding was considered as one of its main potential application scenarios, while keeping it applicable to almost all existing use cases that were already targeted by H.264/MPEG-AVC.
