Video: A Survey Of Per-Title Encoding Technologies

Optimising encoding by per-title encoding is very common nowadays, though per-scene is slowly pushing it aside. But with so many companies offering per-title encoding, how do we determine which way to turn?

Jan Ozer experimented with them, so we didn’t have to. Jan starts by explaining the principles of per-title encoding and giving an overview of the market. He then explains some of the ways in which it works including the importance of changing resolution as much as changing

As well as discussing the results, with Bitmovin being the winner, Jan explains ‘Capped CRF’ – how it works, how it differs from CBR & VBR and why it’s good.

Finally, we are left with some questions to ask when searching for our own per-title technology to solve the problem we have such as “can it adjust rung resolutions?”, “Can you apply traditional data rate controls?” amongst others.

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.
