Video: Comparing AV1, VP9, HEVC, & H.264

Posted on by Russell Trafford-Jones

Comparing AV1, VP9, HEVC and H.264 is quite a task, but Streaming Media’s Jan Ozer is here to take us through it. From MPEG royalties to VP9 browser compatibility, from the AV1 roadmap to HEVC-enabled HLS, this is a comprehensive look at real-world usage of the top four codecs.

This is a key topic because many content distributors and aggregators still use H.264 as their primary, if not exclusive, codec, but the bandwidth savings promised by newer, more powerful codecs are alluring. Those considering a switch must evaluate at least three options: HEVC, VP9, and AV1.

In this session, codec specialist Jan Ozer evaluates the quality of these codecs and compares them to H.264. Learn how much bandwidth you can save with each, and how the newer codecs compare from quality and implementation perspectives.

Video: HEVC Vs AV1 and the Future of the Codec Battle

Posted on by Russell Trafford-Jones

In this debate from NAB 2018, the panel discusses the video codecs which are competing to be the next-generation standard in the OTT environment and, notably, HEVC and AV1 being the front-runners. The debate on which video standard is best suited to our industry is in full swing especially as the Alliance for Open Media released AV1 at the NAB Show and Apple is supporting HEVC in its products and has decided to join the Alliance for Open Media as a founding member. This panel discusses the pros and cons of HEVC and AV1, and also put in perspective content-aware encoding techniques with AVC that might be a strong challenger in the short term for OTT distribution.

Video: Comparing Per-Title Encoding Options

Posted on by Russell Trafford-Jones


In this video from Streaming Media East 2018, Jan Ozer looks at per-title encoding. Jan presents detailed results from tests of competing methods to help us understand the dos and don’ts of encoding and VQ and how these methods allow higher resolution profiles in ABR ladders.

  • What is ‘per-title’ encoding and why is it important?
  • What are the different methods? (CRF, SABL, Context Aware, EuclidIQ Rithm)
  • The Tests
  • The Results

Video: Choosing B-frame Interval and Reference Frames

Posted on by Russell Trafford-Jones


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.
