A new generation of CODEC demonstrates better coding efficiency

As higher definition video is gradually popular, the new generation of CODEC shows better coded efficiency. With the new generation of CODEC, AV1 and VVC (upcoming d''cisions) have become a standard, and their coding efficiency of more high-definition shows an advantage. The MSU released the results of 4K video encoding efficiency evaluation results in 2020, and the public released data is shown here (http://compression.ru/video/codec_comparison/hevc_2019/#4k_report). In the 1FPS gear test, the micro-frame Aurora, Huawei HW265 and Mainconcept HEVC's YUV-SSIM objective score rank first three. In terms of encoding speed, SIF, BYTEDANCE V265 and SVT-AV1 rank top three. Coding speed and quality weighing, Bytedance V265 and micro-frame AURORA, Huawei HW265 occupies two extremes. Code rate control is compared. The code rate control is stable, which will affect the stability of the streaming system, such as the load of the CDN, the client's statter, and more. In the 20FPS file, Huawei HW265, Bytedance V265 and Mainconcept HEVC's YUV-SSI objective Quality score ranam. Two AV1 encoders did not participate in this test. In terms of coding speed, VP9, ​​SVT-HEVC and SVT-VP9 rank first three. In the end, MSU gave his own summary results: At the 1fps gear, it can also be understood that it is better to pursue the ultimate compression efficiency (ie, the video oncast field scene), the microfield Aurora and Huawei HW265 performance are better. Under the 20fps gear, Huawei HW265, Bytedance V265's coding efficiency is better. , Read full text, original title: MSU release 2020 4K coding efficiency evaluation results Article Source: [Micro Signal: Livevideostack, WeChat public number: microwave radio forum] Welcome to add attention!
