Zhou Wang explains how to compare HEVC & AVC with AV1 and shares his findings. Using various metrics such as VMAF, PSNR and SSIMPlus he explores the affects of resolution on bitrate savings and then turns his gaze to computation complexity.
This talk was given at the Mile High Video conference in Denver CO, 2018.
Jigsaw24’s Chief Engineer, Phil Crawley, explains video codecs from the fundamentals up. Codecs touch every part of the broadcast chain and are a vital part of the industry as much as of day to day life. So it’s worth brushing up or learning the basics to help you to fully understand what’s happening with today’s codecs, whether that be HEVC, AV1, JPEG XS or trusty MPEG4.
As the first post of 2019, please allow me to say Happy New Year and to thank you for the time you spend coming to the website, following by email and/or following on social media. Your visits, interest and recommendations are very important and highly appreciated. 2018 ended with being nominated for the Royal Television Society Website of the Year. Whilst the hardworking and knowledgable people at The Broadcast Bridge won, and deservedly so, I hope you’ll be as mighty pleased as I was to see a non-commercial site pitted against the best in the industry. Be assured that The Broadcast Knowledge always aims higher than before so what better motivation than to top that!
As we set our sights on 2019, there’s time for a brief look back at the top video linked to here on The Broadcast Knowledge in 2018. Looking back at the stats, it has the most page visits and the most clicks, so let’s revisit this panel on AV1 and HEVC. It’s not often you get the likes of Facebook and Harmonic sharing their latest research on stage with companies like Harmonic and Bitmovin who are very active in the Codec community, so it’s no surprise this piqued the interest of many.
This panel took place during NAB 2018 when AV1 had just ‘released’ the AV1 codec at the show but the points discussed are as relevant today as they were then including the adoption of HEVC in the marketplace. Having said that, do check out the AV1 and HEVC tags to see what more recent discussions there have been including a discussion of the future of video codecs at Streaming Media East 2018
Thierry Fautier, speaking at SMPTE 2017, explains the planned advances in Codecs for the next 5 years explaining the new techniques and likely future abilities of the different codecs. Based on his technical paper, Thierry explains efforts to ‘boost’ HEVC and, in the future JVET which complements his comprehensive look across VP9, HEVC, AVC, JVET and AV1.
From VideoLAN’s Video Dev Days event 2018, this talk discusses the latest updates to x265, a free software library and application for encoding video streams into the H.265/MPEG-H HEVC compression format, released under GNU GPL.
Pradeep Ramachandran, Principal Engineer at Multicore takes us through:
11th October 2018, 18:00 BST
Location: IET London, Savoy Place
Whilst many of us in the broadcast industry know current technology well, we would be wrong to overlook learning from the past and few can say we remember it all. This talk Former BT Chief Science Officer, Mike Carr, and current President of the IET promises to be a great reminder of the achievements of the past and why, for better or for worse, they have given us the technological landscape we work in today.
This Presidential address will overview the highlights and evolution of video compression engineering, starting with the relative simple schemes of the late 1970’s through to latest sophisticated techniques demonstrating how digital compression has played such a key part in enabling video as we use it today.
The talk is free to attend at Savoy Place, near Embankment, Central London. To register, you need to sign up for a free IET account. Following the talk is an optional paid dinner. Access to the talk is free and requires only registration!
