There is so much talk about HDR, wide colour gamut (WCG), ‘Better Pixels’ and all the TVs seem to interpolate motion up to 100Hz or above, that it’s good to stop and check we know why all of this matters – and crucially when it doesn’t.
SMPTE’s new ‘Essential Technology Concepts Webcasts’ are here to help and for the first webcast, David Long will look at the fundamentals of colour, contrast and motion in terms of what we actually see.
This promises to be a great talk and, the chances are, even people who ‘know it already’ will be reminded of a thing or two!
Following on from last week’s post part II is here. Wes Simpson looks at use of IP in Remote Production/Remote Integration (REMI) and finished with a panel discussion including Newtek and Grass Valley, a Belden brand.
This video talks about:
Why Broadcasters need networking?
Typical Live remote sports broadcast roles
Overview of video & audio Signal types
HDR & Wide Colour Gamut (WCG)
Data (metadata, scripts etc)
REMI – Remote Integration, AKA ‘Remote Production’ in Europe.
Overview of what tasks can be done at base, what still needs to be done ‘on-site’
In this Tech Talk we shall hear from researchers and vision scientists, how they are ensuring the precision of HDR and colour in image capture.
Today’s imaging technology strives to produce a viewing experience which is, as far as possible, identical with that perceived by the human visual system. Strangely, one limiting factor in high dynamic range (HDR) design has been that existing measurements of the human vision have not been sufficiently accurate. Another of these issues is skin tone: humans are particularly sensitive to skin colour – regarding it as an indicator of well-being. The accurate portrayal of this subtle parameter is therefore particularly important. A further interesting image quality issue is slow motion – here we explore the development of an 8K UHD 240fps camera and slow motion capture and replay server.
From VideoLAN’s Video Dev Days event 2018, this talk discusses the latest updates to x265, a free software library and application for encoding video streams into the H.265/MPEG-H HEVC compression format, released under GNU GPL.
Pradeep Ramachandran, Principal Engineer at Multicore takes us through:
Vimeo’s Vittorio Giovara discusses ways to improve viewer retention by improving videos paying attention to colour space and colour volume. This talk covers how and why High Dynamic Range (HDR) works, Wide Color Gamut (WCG), 10-bit vs 8-bit video and also discusses the importance of frame rate on viewer retention.
After all, 4K has gotten most of the headlines, but there are other ways to improve the quality of your streaming video that have even more visual impact. This talk explores video colorimetry, ranging from video quality concepts to the latest trends in the industry. Vimeo’s experience is used as a practical implementation example and showcases how new compression technologies are deployed for the benefit of creators and their audiences.
This isn’t just about pretty videos, Vittorio shows the economic benefits of producing a better product.
In the past few years, the industry has been trying to improve the end user experience to have a higher spatial (pixels), temporal (framerate) and spectral (bitdepth) resolution.
This talk from Vimeo’s Vittorio Giovara and Ronald Bultje from Two Orioles will explore the high-bitdepth element of this improved user experience. Technically, this is usually referred to as 10-bit video, since, historically, the video user experience has been largely based on a 8-bit world. We will explain marketing terms like HDR, UHDTV, explore high bitdepth-support in commonly used video coding software, and showcase how these work together to improve your video coding efficiency and end user experience.
Mark Watson from Netflix examines how to combine SDR and HDR video from many sources into one seamless experience. How do you manage the different colour spaces, the difference in dynamic range, the types of HDR? Mark talks about how the different delivery formats differ and presents ways in which they can be unified, representing the work that Netflix is putting in to create a rich, seamless and dynamic auto-playing user experience.
A review of current technology and real-world deployments
The WOW factor: Why HDR?
HDR standards: HLG, PQ or HDR10 variants?
Content availability: HD or UHD?
Consumer displays: Mobile phones or 4K/8K TV?
HDR distribution: Broadcast, OTT or 4G/5G?
Real world deployments
The competition for viewers’ eyeballs and their disposable income has never been fiercer. Great picture quality is one weapon that service providers – especially broadcasters – can deploy to attract and retain viewers.
It’s true that millions of 4K ready TVs have been sold, but in practice most TVs sold before 2017 don’t have any support for HDR at all. Many different variants of HDR have also emerged in an attempt to offer higher quality coupled with some backwards compatibility with those early TVs, but broadcasters have been perhaps understandably reluctant to commit to producing 4K or HDR content with the costs of the ill-fated 3DTV still on their books.
This webinar looks at HDR in general and the different variants that have emerged. The drive for 4K, or even 8K, content and displays is contrasted with consumers’ willingness to watch full HD with HDR on the latest mobile phone displays… Register Now!
