Codecs

This post explores the economic factors to consider when choosing a preset for the SVT-AV1 codec. It’s adapted from a new lesson added to the course, Encoding with the AV1 Codec. While this analysis uses the SVT-AV1 codec, it’s useful for choosing a preset for any codec.  I’ve always considered codec preset selection a cost and quality-driven decision. You see …

Just a quick note that I’ve updated the course, Streaming Media 101: Technical Onboarding for Streaming Media Professionals, with new codec lessons for H.264, VP9, HEVC, AV1, VVC, LCEVC, and EVC. Each lesson, which vary in length from 12 to 20 minutes, covers the topics shown in the agenda below. The lessons are designed to bring the students up to …

My State of Video Codecs 2022 article is up on Streaming Media Magazine. The article identifies the most significant announcements from the last year relating to H.264, VP9, HEVC, AV1, Versatile Video Coding (VVC), Low Complexity Enhancement Video Coding (LCEVC), and Essential Video Coding (EVC). If you’re looking for a good way to catch up with these codecs, you’ll find …

I’ve been wondering if publishers still care about constraining their maximum bitrates (see here for more background), so I grabbed my copy of youtube-dl and performed a little study. The TL/DR version seems to be that new media sites like YouTube, Facebook, and Vimeo don’t strictly adhere to the typical 200% constrained VBR limit while traditional publishers seem to, though …

Every year around this time, like an early Christmas present, Bitmovin releases its Annual Video Developer’s Report, a must-read for all streaming media professionals. Now in its fifth year, the report contains valuable insights regarding codec usage, production workflows, and the issues that are keeping streaming professionals up at night, literally or metaphorically. To produce the report, Bitmovin surveyed 538 …

VVC reached First Draft International Specification in July 2020. We’re about 18 months past that date and it’s useful to check in on VVC progress to date, including licensing, performance, chipset development, and trials. VVC Patent Owners Video quality is nice, but money makes the world go-’round, so let’s start here. Understand that video compression standards like VVC will have …

Given that VVC is top of mind right now, I just wanted to report that IAM has announced that it appears that Apple has purchased 14 VVC-related patents from a Korean inventor. IAM is connecting a lot of dots to (I think) make this claim, which goes something like this. A Korean inventor set up a company that performs video-related …

This video compares VVC, EVC, and LCEVC with H.264, HEVC, and AV1, considering quality, USP, royalty status, key stakeholders, producibility, and playability. You can watch an archived version of the webinar on YouTube by scrolling to the bottom of the page. You can download the handout here. This video is a webinar comparing VVC, EVC, and LCEVC with H.264, HEVC, and …

OK, I’ll say it. As far as I know, this is the first time any study has compared the quality and performance of codecs representing Essential Video Coding (EVC), Versatile Video Coding (VVC), and Low Complexity Enhancement Video Coding (LCEVC), as well as AV1, HEVC, and H.264. It’s not as exhaustive as I would like but the results should help …
