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: email@example.com to get involved.
EBU BPN 114 provides EBU Members with an introduction to HDR.
EBU BPN 120 gives a feeling for what EBU Members are planning for the 2020-2025 time period
EBU Tech Report 038 contains the results of subjective tests, which show HLG10 and PQ10 are equivalent in terms of visual quality.
EBU Tech Report 047 provides an overview of the quality of professional HDR monitors and how to measure them.
EBU Tech 3320 specifies the characteristics of Grade 1,2 and 3 professional monitors. It includes HDR since version 4.0.
EBU Tech 3325s1 defines 10 additional test colours for grade 1 professional HDR monitors.
EBU Tech 3373 specifies UHDTV HDR (HLG) Colour Bars for use in operation and comes with example images (1080 and 2160 rasters) in 16-bit TIFF and v210 (Quicktime) for use in equipment.
EBU Tech 3374 specifies a handy EOTF Test Chart to visually check your set-up; a TIFF implementation is available here.
EBU BPN 121, EBU BPN 122 and EBU BPN 123 provide the results of the video quality analysis (test plan here) of popular studio codecs from Avid, Panasonic and Sony (Apple expected next).
Live HDR Workshop
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.
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.
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.
