Lars Borg explains to us what problems the SMPTE ST 2094 standard sets out to solve. Looking at the different types of HDR and Wide Colour Gamut (WCG) we quickly see how many permutations there are and how many ways there are to get it wrong.
ST 2094 carries the metadata needed to manage the colour, dynamic range and related data. In order to understand what’s needed, Lars takes us through the details of the HDR implementations, touching on workflows and explaining how the ability of your display affects the video.
We then look at midtones and dynamic metadata before a Q&A.
This talk is very valuable in understanding the whole HDR, WCG ecosystem as much as it is ST 2094.
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.
