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: The AV1 Video Codec

AV1 implementations are still being worked on along a number of fronts and the business cases are starting to shake out. Here’s a developer-focussed look at AV1 from patents to the way it works and to lessons learnt implementing it.

It was last year that the Alliance for Open Media released its next-generation video codec AV1. It achieves better compression than proprietary competitors, while its patents can be licensed via a royalty-free, open-source friendly license. With a broad array of industry support including all major browser vendors, many hardware partners, internet streaming video and conferencing providers, many think this is the best chance yet to create a successful video codec of its type that achieves wide deployment.

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!

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: Integrating Machine Learning with ABR streaming at YouTube

In another great talk from Demuxed 2018, Steve Robertson from YouTube sheds light on trials they have been running, some with Machine Learning, to understand viewer’s appreciation of quality. Tests involve profiling the ways – and hence environments – users watch in, using different UIs, occasionally resetting a quality level preference and others. Some had big effects, whilst others didn’t.

The end-game here is acknowledging that mobile data costs money for consumers, but clearly YouTube would like to reduce their bandwidth costs too. So when quality is not needed, don’t supply it.

The talk starts with a brief AV1 update, YouTube being an early adopter of it in production.

Video: High Dynamic Range in AV1

Google and University of Warwick explain AV1, its current status and how its can support HDR with WMG’s trueDR at the IABM’s Future Trends Theatre at IBC 2018.

Matt Frost from Chrome Media takes the stage first giving an overview of AV1’s goals, objective quality tests and where we are in AV1’s timeline as well as answering many questions from the audience.

Next Alan Chalmers from University of Warwick explains how they added HLG, HDR10 (PQ) to AV1. Also added are new, scene-referenced, HDR methods which Alan explains the works of and reasons for.

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.

Video: Mozilla TechSpeakers – AV1 Video Codec

AV1 is much talked about. We know what it promises, but how many of us remember what it does and why it is so promising?

Here, Mozilla – a member of the Alliance for Open Media – takes us through what AV1 is, how it works, why it promises to fare better than HEVC.

Covering:
• Brief history of video viewering royalty codecs
• What makes AV1 different
• The tools AV1 uses
• Quality Benchmarks
• HEVC Licensing
And much more

Webinar: Advanced Encoding & Transcoding with the Experts

Thursday 27th September 2018, 19:00 BST / 11am PT / 2pm ET

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
