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.
In this talk, Color Me Intrigued, given at Demuxed 2017, Vittorio Giovara, Senior Video Encoding Engineer at Vimeo, sheds light on colorspaces – what they are, how and why they work, why we should care about handling edge cases properly. Starting with historical design choices, venturing through current standards such as BT.709, and arriving at modern times with High Dynamic Range, the focus will be on practical applications on the web and in broadcast.
A great primer for those who need it, and great revision for the rest!
