Video: Get Ready For A Multiple Codec World

The codec world is fragmenting. None of the new entrants on to the market is expected to ever gain the universal status that AVC enjoys. This panel from Streaming Media East takes a look at how to prepare for this.

The panel kicks off discussing the differences between AVC and HEVC, VP9 and AV1 and moves on to discuss the pros and cons of supporting multiple codecs. Tarek from Twitch explains its partial adoption of VP9 – the reasons that it makes sense but the overheads which it brings the business.

Vittorio Giovara from Vimeo explains their reasons for using HEVC including their drive to be able to encode and deliver 10-bit video. Ellation’s Subhrendu Sarakar makes the point that managing codec changes and bitrate changes needs to be done carefully to ensure viewers that notice the change understand them and don’t feel there has been a reduction of quality.

After a brief discussion of encoding strongly characterised video types such as anime and gaming, the conversation moves on to AV1 and migrating from VP9 and there is an audience question on HEVC licensing and the lack of use of SVC (Scalable Video Coding)

It’s now relatively well known that Twitch deployed VP9 using FPGAs rather than as a software encoder which was the only way to get the real-time speed at 1080p60. The panel discusses encoding speed both in the encoder and decoder for VP9 and AV1 then finishes with a Q&A from the audience.

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

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)

Video: A Jaunt Through Colour Technology In Video


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!
