Just a quick note to let you know that I’ll be speaking twice at NAB in Las Vegas next week; once as host of a panel discussion on HEVC and AV1, the other a session on how to use objective quality metrics to assist encoding configurations. Details are below.
If you’re at NAB and free, and the topics are relevant to your practice, I hope you’ll join me.
Track C: Applying Quality Encoding Metrics For 2D And VR Video
Date: Wed. April 11, 10:15 AM – 11:15 AM, Location: Westgate Pavilion 3
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 with metrics such as CRF, PSNR, Spherical PSNR, Weighted Spherical PSNR, and VMAF, you can assess the quality delivered by each stream and its relevance to the 2D and particularly the 360° VR adaptive group. This presentation identifies several key 2D and 360° VR 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.
Track B: HEVC vs. AV1 and The Future Of The Codec Battle
Date: Wed. April 11, 1:30 PM – 2:15 PM, Location: Westgate Pavilion 2
Description: Today, several video codecs are competing to be the next-generation standard in the OTT environment, with 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 is all set to release 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 will discuss 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.
