I help companies train new technical hires in streaming media-related positions; I also help companies optimize their codec selections and encoding stacks and evaluate new encoders and codecs. I am a contributing editor to Streaming Media Magazine, writing about codecs and encoding tools. I have written multiple authoritative books on video encoding, including Video Encoding by the Numbers: Eliminate the Guesswork from your Streaming Video (https://amzn.to/3kV6R1j) and Learn to Produce Video with FFmpeg: In Thirty Minutes or Less (https://amzn.to/3ZJih7e). I have multiple courses relating to streaming media production, all available at https://bit.ly/slc_courses. I currently work as www.netint.com as a Senior Director in Marketing.

Encoding DV and Analog Footage in FFmpeg

There are two mostly vestigial problems that I didn’t address in Learn to Produce Video with FFmpeg in 30 Minutes or Less because so few people encounter them. These are deinterlacing and aspect ratio mismatches. Now I’m writing a textbook with a greater scope, so I had to learn how to deal with both in FFmpeg. These will make it …

Sorenson Squeeze RIP

Sorenson Squeeze was one of the first encoding tools that many streaming professionals used and now it’s officially end-of-lifed as you can see from the featured image atop this page (from here). It’s not really a surprise; in 2015, I interviewed new Sorenson CEO Marcus Liassides who described how Sorenson would be focusing on building tools to drive the future of …

Choosing a Cloud or On-Premise Encoder

As corporations move their compute resources into public and private clouds, and other virtual environments, most encoding vendors are doing the same with their encoders, though not all markets are moving at the same speed. In my Streaming Media article, A Hybrid Approach Guides the Changing Face of On-Prem Encoding, I spoke with about 13 vendors, including Harmonic, Telestream, encoding.com, Comprimato, …

Codec Overview on Streaming Media Website

AV1 has been all consuming from a mindshare perspective for many streaming professionals, but the fact of the matter is that unless you’re distributing stream quantities on par with Netflix, YouTube, Amazon, and Hulu, AV1 won’t be relevant for at least two years, maybe longer. I discuss why in my Streaming Media article, Return of the Codec Wars: A New Hope—a …

Premiere Pro Won’t Load AVCHD Audio? FFmpeg to the Rescue

If you’re trying to load AVCHD files into Premiere Pro and you’re on Windows 7 or earlier, the AVCHD video will likely load without the audio file. That’s because instead of supporting Dolby decoding natively in Premiere Pro, like they used to, Adobe now piggybacks off the operating support in Windows 8 and beyond. Since Windows 7 doesn’t support Dolby …

Finding the Equivalent x264 Commands for FFmpeg

Most of the x264 commands that I use in FFmeg are simple and well documented. Today, I had to duplicate a Handbrake preset that included some obscure x264-specific configuration options like the following: cabac=0:aq-mode=3:slices=24:direct=auto:subme=8:trellis=1:deblock=-2,-1:me=umh Cabac, I got, but most of the rest I use the default setting for the selected preset. Since Handbrake was displaying x264 commands which are different …
