Fine-Tuning Your Adaptive Encoding Groups With Objective Quality Metrics

Click over to the main article to download the presentation. Here's the description. 

Choosing the number of streams in an adaptive group and configuring them is usually a subjective, touchy-feely exercise, with no way to really gauge the effectiveness and efficiency of the streams. However, by measuring stream quality via metrics such as PSNR, SSIM, and VQM, you can precisely assess the quality delivered by each stream and its relevancy to the adaptive group. This session identifies several key objective quality metrics, teaches how to apply them, and provides an objective framework for analyzing which streams are absolutely required in your adaptive group and their optimal configuration.

Streaming Media East Presentation: Status of HEVC and Other UHD Codecs

This session explores the current status of HEVC, including an update on the proposed royalty terms and status of High Dynamic Range Specifications, and the status of competitive technologies such as PERSEUS, VP9, and the codec from the Alliance for Open Media.

Handout for Codecs and Packaging 2016

Click over to the main article to download the handout. Here's the description.

As video resolutions increase and target playback platforms multiply, video producers must leave their H.264/HLS/HDS comfort zone and expand into HEVC, VP9, and MPEG-DASH. This workshop is divided into multiple segments by target platform to teach you the applicable standards and best strategies for delivering live and VOD adaptive video to viewers on that platform, both with and without DRM. Along the way, you'll learn options for producing H.264, HEVC, and VP9; the status of standards such as the Media Source Extensions (MSE)and Encrypted Media Extensions (EME); and how and when to utilize them. Attendees walk away knowing the technical requirements for delivering to all key platforms and the best practices for making it happen.

Technical Brief: Switch from CBR to VBR to Improve Overall Quality and Avoid Transient Quality Issues

This article explores the differences between constant bitrate encoding (CBR) and variable bitrate encoding (VBR) and recommends that producers still using CBR should switch to 110% constrained VBR to improve overall quality and avoid transient quality issues with CBR. 

Five Signs Your Encoding Ladder May Be Obsolete

Your encoding ladder is the set of encoding parameters that you use to create the various files that you deliver adaptively to your web viewers. These encoding parameters can live in your on-premise encoder, in your cloud encoder, or in your online video platform (OVP). This article describes five signs that indicate that you may need to revisit your encoding ladder.

Here's the description, click over to the main article to download the handouts.  HOW TO: Encoding Live and On-Demand Video Using HEVC Location: Grand Ballroom, Salon G This session explores the current status of HEVC, identifying options for encoding live and on-demand video using HEVC and discussing player options in the streaming and OTT markets. Topics include the comparative quality and usability of HEVC encoders—including encoders from x265 and MainConcept—and techniques for maximizing output quality using both codecs.

Live Encoding and Transcoding Techniques

Here's the description, click over to the main article to download the handouts.

Live event transcoding used to be simple: you did it all in-house and you needed capacious outbound bandwidth, all of which cost a fortune. Now there are more live encoding schemas than you can shake a stick at, including live cloud transcoding and packaging from traditional encoding vendors as well as OVPs, CDNs, and other service providers. In this session, Jan Ozer will survey the available encoding/transcoding options and service providers, and present a structured comparison that includes critical factors such as cost, stream redundancy, packaging flexibility, bandwidth requirements, DRM and captioning support, scalability, and player and distribution network integration.

Transition from Flash to HTML5

Download the handout from this excellent session, with contributions from Jeff Tapper (Digital Primates), John Luther (JW Player), and Mike Callahan (Elemental). 

Transitioning from Flash to HTML5 is a complicated matter involving a change in player and encoding format and, for some, even new DRM, captioning, and advertising insertion technologies. Learn the current status of the Media Source Extensions and Encrypted Media Extensions. Get advice on your options and strategies for existing encoded content libraries and how to plan and implement the transition. A representative from Elemental Technologies describes the MPEG-DASH standard, details how to encode for MPEGDASH, and discusses alternatives for adopting or converting existing content libraries. A representative from JW Player also covers development options for creating a MSE/EME compatible player, including open source and OTS options like JW Player, and presents case studies for successful Flash to MSE/EME transitions.
