Video: AV1 vs. HEVC: Perceptual Evaluation of Video Encoders

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.

Video: HEVC vs AV1

Ian Trow looks at the two big names in the room, AV1 and HEVC to understand them from a business perspective as well as technical.

Speaking at the Northern Waves conference, Ian covers:

  • Head-end options
  • OPEX & CAPEX
  • Cloud vs traditional
  • Encoding challenges and latency
  • Evaluation criteria (Functionality, TCO, Time to Market and more)
  • AV1 for OTT
  • Royalties
  • Encoding Structure
  • CDN Savings
  • AV1 Timeline
  • …so quite a bit then!

[Video]: Video Compression 101

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.

Phil covers:

  • Compressed and Uncompressed video & codecs
  • DCT Principles
  • Intra/Inter-frame compression
  • Acquisition Vs Editing Vs. Transmission codecs
  • Measuring compression effects
  • Codecs Vs File Formats & wrappers
  • Compression concatenation
  • MPEG4, H.264(AVC) & H.265(HEVC)

Top Video of 2018: HEVC vs AV1 and the Future of the Codec Battle

 

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

Sit back and watch HEVC vs AV1 and the Future of the Codec Battle!

Video – Live Streaming with VP9 at Twitch TV

Tarek Amara from Twitch explains their move from a single codec (H.264) to multiple codecs in order to provide viewers an optimal viewing experience.

In this session, Tarek shares findings on VP9’s suitability for live streaming and the technical and industrial challenges such move involves. Covering:

  • VP9 encoding performance,
  • Device and player support,
  • Bandwidth savings,
  • The role of FPGAs
  • plus an overview of how the transcoding platform need to change to enable VP9 encoding and delivery at scale.

This presentation is from the Video Engineering Summit at Streaming Media West 2018.

Video: Next-Generation Video Compression Techniques

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.

Video: IBC Tech Talks: Codec Wars

From IBC, this is an fantastic line-up of 6 experts in the field of codecs who dive deep into the pros and cons of AV1, HEVC and discuss alternative codecs.

Three papers are presented showing the reality of the AV1 implementation to date, why there’s promise and why we’re not there yet.

The event moves on to a panel session which digs deep into HEVC licensing, challenger Codecs such as XVC and PERSEUS, and much about UHD and HEVC adoption.

Meeting: The IET President’s Address – A story of unseen engineering: digital TV compression

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!
