On a LinkedIn post here, Johan Skaneby asked: Technical comparisons and documentation on different codec performance are very interesting and important, but all development of technologies are always closely related to market requirements and business models. My experience is that the challenge for decision-makers in existing and profitable distribution workflows is to understand the business…
This post provides an introduction to video codecs. It’s an entry-level article designed to help streaming newbies understand what codecs are, what they do, how to compare them, and why they succeed or fail.

VVC is one of the three codecs to be launched by MPEG in 2020. I wrote about VVC extensively here (business side) and here (technical side), and wanted to provide some quick updates. By way of background, codecs have two sides, the performance side, and the business side. In this short article, I’ll address both.…
I’ve spent the last two months testing four AV1 codecs accessible via command-line arguments and I start testing VVC codecs next week. Trying to fairly and accurately test the capabilities of these codecs turned out to be a pretty grueling and messy task. The key challenge, of course, was creating the optimal command string for…
