Video: Choosing B-frame Interval and Reference Frames

Jan Ozer from Streaming Learning Center takes us through the basics and ways to use B-frames in MPEG encoding. Covering:

  • Common B-Frame settings
  • Choosing the right B-Frame interval
  • What reference frames do
  • Understanding quality/encoding-time trade-off
  • Choosing the number of reference frames.

Great for remembering what you once knew or learning MPEG in a bit more depth, anyone who knows a little about MPEG encoding can benefit from this recorded webinar.

Video: How to Fine Tune your Adaptive Encoding Groups with Objective Quality Metrics

In this on-demaind video, Streaming Learning Center’s Jan Ozer explains objective metrics to us and how they can be used to build better ABR ladders.

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, SSIMplus, 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.
