Choosing the Data Rate for your Mezzanine Files

As more and more producers move their encoding to the cloud, the data rate for the mezzanine files is significant factor for upload time and bandwidth and storage costs. The big question is, how much extra output quality do higher quality formats and higher data rates really afford. As you’ll learn in this article, the answer is not that much.

Apple Makes Sweeping Changes to HLS Encoding Recommendations

In the past twelve months, Apple has made sweeting changes to their recommendations regarding the production of HTTP Live Streaming (HLS), including the (gasp!) depracation of the venerable TN2224.

How To: Build Your Own Cloud Encoder With FFmpeg

Here's the session description; click over to the main article to download the handout.

Almost all of the commercial cloud encoding services, and many of the largest streaming producers encode in the cloud using FFmpeg. It’s cheap, relatively simple, and highly effective. To accomplish this yourself, you need two basic skill sets; first how to encode with FFmpeg, and then how to automate, schedule, and manage the encoding processes. This presentation will detail how to produce H.264 files with FFmpeg, and describe the tools and techniques available to simplify the automation and management of these encoding jobs for both live and VOD encoding.

D101 - How To: Fine-Tuning Your Adaptive Encoding Groups With Objective Quality Metrics

Here's the session description; click over to the main article to download the handout

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 presentation 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

W2: Encoding 2016: Codecs and Packaging for PCs, Mobile and OTT/STB/Smart TVs

Here's the description for my workshop at Streaming Media West:

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, attendees 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.

Cloud Pricing Survey Shows Hybrik Least Expensive Option By Far

I recently finished a white paper comparing the pricing for a new cloud encoding service named Hybrik with multiple cloud providers, including Amazon Elastic Transcoder, Microsoft Azure, Bitmovin, encoding.com, Telestream Cloud, and Zencoder. The white-paper was sponsored by Hybrik, and you can download it by clicking over to the main article.
