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.
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.

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!
Mike is the former Chief Science Officer for BT and responsible for the company’s world-leading research and commercial exploitation unit, including patent licensing and corporate venturing activities
During his first 15 years with BT’s Labs his career has focused on the research, development and practical design of real-time audio/visual and multimedia communications systems.
He has several patents to his name in the field of video compression and is the holder of two prestigious BT awards; the Martlesham Medal for R&D (1992) and the BT Gold medal (1994) for leading multimedia product developments.
In 1998 he was elected President of the Digital Audio-Visual Council (DAVIC) a non-profit association based in Switzerland and representing 160 companies in more than 25 countries, focused on developing specifications for audio-visual systems. From 1999 Mike was based in Silicon Valley, California, USA where he established BT’s US Technology office and Corporate Venturing activity.
Mike is a Fellow of the Royal Academy of Engineering. He received an OBE for “services to innovation” in 2017.

Encoding and transcoding are at the heart of every video service and solution, and the codec and format landscape has never been more crowded. Publishers are wringing the most efficiency out of H.264 while making the move to HEVC/H.265 and AV1—and keeping an eye on other proprietary codecs. On top of all that are considerations like video optimization, bitrate ladders, and per-title encoding.
Join this expert panel as they discuss the latest in encoding and transcoding, including the following:
The state of the art in encoding efficiency in 2018
How per-title encoding and machine learning can increase quality and decrease delivery costs
How to build flexible and cost-effective encoding solution
The latest developments in video encoding platforms and infrastructure
The benefits of contribution to distribution encoding and transcoding
The next big advances in encoding and transcoding, including AV1
This joint webinar from the IABM and V-Nova, will dive into the current state of the compression market, exploring new technologies and assessing compression costs and benefits to broadcasters, operators and OTT providers.
“More with less,” this has always been the compression mantra since the beginning. With the rise of new media and the emergence of immersive formats such as UHD and VR, compression vendors have been again asked to deliver better quality at a reduced bit-rate.
Industry trends driving demand for improved video compression
Shift from hardware to software (and virtualisation) – impact on compression vendors and benefits for operators
The benefits of next-generation video compression for AVOD and SVOD services. What are the dynamics? How much of an effect can it have on a streaming video business?
The rise of AI – how artificial intelligence can improve compression economics
Immersive formats – UHD/VR demand by end-users; economics of delivering these formats and how best to do so
HEVC, AV1 and PERSEUS Plus – the various factors dictating what codec to choose and in which scenarios they have most value
In this talk from Streaming Media East 2018 Paul MacDougall from Bitmovin discusses moving from h.264 to newer codecs.
Video streaming is in transition towards the next generation of video codecs, offering to double the quality while lowering the required bandwidth. As the successor crown to the ubiquitous AVC/H.264 is still up for grabs, major content providers and device manufacturers are throwing their weights behind competing formats – HEVC/VP9/AV1 – leading to market fragmentation, specifically within web environments. To deal with this challenge, OTT services need to support multiple codecs in an efficient way.
In this presentation, Paul talks about how to evaluate the benefits and the tradeoffs of embracing next generation compression technologies in your media workflow. He looks at the state of the browser market and compatibility, current deployment percentages and then how to decide whether to do multiple encoding on an asset or not. Paul finished with advice on playback and the state of smart TVs.

The Tech Breakfast at Jigsaw24 continue this time with a look at video compression fundamentals. Codecs are a vital part of the industry and almost part of day to day life, so the experts from root6, Phil Crawley and Matt Ward, will help you get a grasp of the basics and understand what’s happening with today’s codecs, be that HEVC, AV1 or trusty MPEG4. All this, plus a pastry and a drink!
