Video: Understanding Frame Rate by Mark Schubin


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?

Video: What causes delays in broadcast networks? Linear Vs. Live Streaming


Video: 24 minutes
A brilliant look at all the delays in broadcasting from traditional linear channels to live internet streaming. Anders Cedronius from Net Insight discusses what is acceptable and what is achievable in today’s world? Can live streaming delay match, or even beat, traditional broadcast delays?

Recorded at Streaming Tech Sweden, a Swedish conference with a dedicated focus on the technology for video streaming. Organised by Eyevinn Technology, this is the meeting place for tech managers, architects, developers and product managers looking to be educated and inspired by experts in this area, network with peers and bring home new thoughts and ideas.

Video: AES & SMPTE 2110 Commonalities and Constraints


Great explanation of how AES67 and @SMPTE 2110 overlap but also where they differ. Including an overview of PTP timing: a perfect follow on from the recent @SMPTEUK meeting on the same topic at Surrey University.
Andreas Hildebrande from ALC NetworkX shows the completeness of the AES67 ecosystem and how different companies interoperate on IABM TV during NAB 2017.
