HDR

High Dynamic Range

The EBU helps its Members use High Dynamic Range (HDR) to provide stunning images. This forms part of the work performed in the EBU Video Systems group.

EBU HLG Colour Bars Webinar

On 27 May 2020, Simon Thompson (BBC R&D) gave a Webinar on the new EBU UHDTV HLG Colour bars. You can find the recording here.

HDR update during EBU PTS 2020

During the EBU Production Technology Seminar (PTS) 2020, live production and post-production has been covered in several demonstrations and a tutorial. More details on the EBU PTS 2020 page.

Testing HDR equipment

The EBU is organizing testing of HDR implementations in various devices. Current focus is on NLEs (Adobe Premiere, Blackmagic DaVinci Resolve, Apple Final Cut Pro) and professional converters.

EBU Members are invited to participate. Send an e-mail to: dejong@ebu.ch to get involved.

Recent presentations

The EBU organized a hands-on workshop for its Members (18-20 Nov 2019) to understand live HDR production aspects. See the HDR Live Production Workshop page for more details, including recordings of the key presentations and their slides.

Video recordings

The following presentations by Andrew Cotton (BBC R&D) provide a wealth of information on HDR (latest at the top):

- HDR Live Production - lessons from the field
- Video Fundamentals HDR & SDR
- HDR TV Production
- UHDTV: Live HDR production best practices <- publicly available.
- HDR from theory to practical implementation
- Building a UHD HDR (incl. WCG) Ecosystem

If you are confused about colour spaces, you are not alone. Birgit Schmidt (IRT) shares her questions and answers in The Colour Confusion.

In How can Dynamic Conversion help to improve live HDR? Lucien Lenzen (Rheinmain University of Applied Schiences) explains how dynamic conversion can help improve HDR and SDR image quality.

You may also be interested in this webinar where Dagmar Driesnack (IRT) and Virginie Drugeon (Panasonic) discuss UHD/HDR distribution aspects.

The "How to migrate from HD to UHD" panel led by Andy Quested (BBC) during the EBU Production Technology Seminar 2019 touches on HDR in terms of broadcasters' production and distribution strategies.

In terms of Members' experiences, see the presentation Daniel Marini (RAI) gave at the EBU Technology Production Seminar 2018 about creating stunning promos in HDR.

Exchange of XAVC test files

EBU Members are sharing UHD HDR material to validate the metadata generated by various production tools. EBU Members have access by joining the Video Systems group.

HDR test material

At the European Athletics Championchips 2018, EBU Members and technical partners trialled UHD HDR HFR with NGA in a live setting. Test sequences of this event are available for technical tests. Conditions and more information you can find on the Test Sequences page.

Selected sequences of the RTS Montreux Jazz Festival 2017 project are available to EBU Members. If you are an EBU Member interested to receive a copy, please send us an e-mail.

How was the Montreux Jazz UHD HDR material created?

Watch the making-of video to understand how the material was created and what kind of learnings RTS obtained from the project. EBU Members may also want to watch the presentation given by Derya Aydemir (SRG/SRR) at the EBU Production Technology Seminar 2018.

The inaugural European Championships in summer 2018 provided a perfect opportunity to test several emerging technologies. This issue of tech-i looks at what was done in terms of both production and distribution, covering advanced video and audio formats and potential 5G approaches.

The advent of High Dynamic Range (HDR) and Wide Colour Gamut (WCG) video naturally leads to consideration of what constitutes a good monitor for use with such signals.
