Get the free report to help you choose between H.264 and HEVC GOP sizes – from 1/2 to 20 seconds – to optimize quality for any type of footage: animation, entertainment, sports, or office. Quickly learn which GOP size is best with the help of VMAF metrics.
Read MoreWPP parallelization can be improved by slicing, reducing start lags and exploiting threads more effectively. Splitting pictures into sub-regions allows thread n+1 to begin working after only one CTU has been completed from thread n.
Read MoreIn November 1993, work began on MPEG-2 in Seoul. Three Committee Drafts were approved at the Friday afternoon plenary. Besides MPEG-2, activities such as DSM-CC and MPEG-4 were also happening, producing over 1 million copies. Photocopy machines worked 24 hours a day.

Apple’s introduction of AV1 aims to improve streaming quality while reducing upfront costs and bandwidth requirements, but its adoption could create a tech gap between big and small players. Success depends on collaboration for an open-source, royalty-free codec, so everyone can benefit from AV1.
Read MoreAdopting HEVC encoding can result in bitrate savings of up to 40%, with average savings at 15-20%. Cloud computing and optimized encoders may help reduce compute costs. CDN savings are typically only 5-10%, limited by connection speed requirements.

Codec licensing has become more complex due to web streaming requirements, leading to multiple patent pools and royalty-free alternatives such as VP8, VP9 and AV1. Patent holders are focusing on services and content to recoup costs while streaming services are avoiding royalties with the CENC and CMAF technologies. HEVC adoption is slow due to an unsuitable licensing model.Codec licensing has become more complex due to web streaming requirements, leading to multiple patent pools and royalty-free alternatives such as VP8, VP9 and AV1.

Read MoreAvanci Video, founded by Marconi in 2017, provides a licensing platform of AV1, HEVC, VVC, MPEG-DASH, and VP9 to reduce risk for content providers. Licensors LG and Huawei contribute, while internet streaming companies are targeted for MPEG-DASH and H.264/H.265. The platform levels the playing field and provides regular, predictable returns for licensors.Avanci Video, founded by Marconi in 2017, provides a licensing platform of AV1, HEVC, VVC, MPEG-DASH, and VP9 to reduce risk for content providers.

This paper presents a VVC/H.266 encoder capable of 8Kp60 10-bit HDR real-time encoding with 24% lower bitrate than SpinHEVC. Tests on Intel Xeon Scalable Processors showed up to 70 fps at 30 Mbps and 40 Mbps at 60 fps for 8K video, proving its viability. It had minimal latency and MS-SSIM study revealed higher quality compared to HEVC and AV1. Future research will optimise it further.This paper presents a VVC/H.266 encoder capable of 8Kp60 10-bit HDR real-time encoding with 24% lower bitrate than SpinHEVC.
