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!
We all need this occasionally – a reminder of the fundementals of watching video. Mark Schubin talks us through framerates from the earliest days of the motion picture industry when scientists, engineers and filmmakers collaborated on advancing the technologies that make motion pictures the most dynamic of art forms. Frame rates and colour space require common standards for industry-wide adoption.
Recorded at SMPTE Toronto, we see how in viewing tests, increased frame rate delivers a greater sensation of improvement than increased resolution (at a fraction of the increase in data rate), but some viewers of the higher-frame-rate Hobbit found the sensation unpleasant.
How does frames-per-second translate into pixels-per-screen-width? One common frame rate is based on profit; another is based on an interpretation of Asian spirituality.
Will future frame rates have to take image contrast into consideration? We are all involved with some part of the colour science pipeline as it spans filming to final display, and all the complex steps in between. In the last several years the subject of color management has become a colossal issue in the visual effects community. Modern media projects get content from a wide variety of sources. So how do we get all of this content to play nice together in a production environment?

Mark Yonge, AES Standards Manager, takes us on the journey of how AES67 came into being. This talk from 2015, builds on the clear indications that IP was the way forward up the technologies underpinning the standard and the implications for us on the new ways of working.
In a recorded talk at an AES UK Section meeting, Mark talks about delays, PTP, multichannel audio and much more.
