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. Fraunhofer’s VVenC Sets New Standards …

Pleased to share another five-star review of my online course Streaming Media 101: Technical Onboarding for Streaming Media Professionals. As the course tagline details, “This course teaches the fundamentals and skills necessary to succeed in a streaming media-related job, whether you’re producing and distributing streaming media or creating the tools, technologies, and services necessary to do so.” A recent student, …

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 video encoding command string for each codec. While …

I’m teaching two boot camps (virtually) at Streaming Media West, one for VOD and the other for live streaming; each costs $199. The courses are designed for newbies who need to get up to speed quickly on these topics. Here’s the information for both. W1. Streaming Media Bootcamp, Part 1: Encoding, Packaging, And Delivery For VOD Monday, October 5: 8:00 …

Jan Ozer here. I spent the last 2 months working with four AV1 codecs, benchmarking them against each other and x264 and x265. I’m presenting my findings in this for-fee 75-minute webinar ($149.99).  There are two parts; the first shares what I learned about the codecs, and the second details what I learned about encoding with them and creating the …

This lesson is derived from my book, Learn to Produce Videos with FFmpeg In 30 Minutes or Less ($34.95), and my course, FFmpeg for Adaptive Bitrate Production ($29.95)  (which includes a PDF copy of the book). Don’t just learn FFmpeg; become an expert in video compression.  Overview: Setting your I-frame interval in seconds rather than frames allows you to use …

While standards-based video codecs like H.264 and HEVC tend to dominate, standards-based video quality metrics have never risen to the same usage or attention level. With two innovative and highly accurate metrics now available from the ITU-T, this may change in the near term. Briefly, these models are: ITU-T Rec. P.1203, which calculates the quality of HTTP Adaptive Streaming (HAS) …

Note: This update details how to compute VMAF with FFmpeg on Windows. From my perspective, this feature has gotten progressively less usable and increasingly frustrating. Documentation is poor and the syntax is idiosyncratic and hard to use. If you have any alternative, like Moscow State University’s Video Quality Measurement Tool, I would spend the money and get something that works …
