Video: An overview on 10-bit video — UHD, HDR and Coding Efficiency

Posted on by Russell Trafford-Jones

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.

Introduction: Josie Keller (JWPlayer)
Presenters: Vittorio Giovara (Vimeo), Ronald Bultje (Two Orioles)

Webinar: UHD & HDR

Posted on by Russell Trafford-Jones

Today at 14:00 GMT! 8th March
This Webinar covers Ultra-High Definition (UHD) Television and related technologies such as Higher Dynamic Range (HDR), Higher Frame Rates (HFR) and Next Generation Audio (NGA) in distribution.

What is the impact of Higher Frame Rates? What about Higher Dynamic Range? The German Institut für Rundfunktechnik (IRT) was involved in various subjective tests for HDR and HFR, and the IRT’s Dagmar Driesnack will cover those findings in her presentation.

Both features are also included in the latest DVB (Digital Video Broadcasting) receiver specification. Virginie Drugeon will present on DVB’s updated audio-visual coding specification, TS 101 154, which adds support for HDR, HFR and Next-Gen Audio.

Webinar Agenda

  1. Introduction
  2. UHD Features and Tests – Dagmar Driesnack
  3. Q&A
  4. UHD in DVB Distribution Standards – Virginie Drugeon
  5. Q&A
  6. What is next? – Interactive session with Dagmar Driesnack and Virginie Drugeon

Video: Understanding Frame Rate by Mark Schubin

Posted on by Russell Trafford-Jones


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?
