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.

Webinar: Simplifying Encoder Purchase and Configuration Decisions with Real Time Quality Metrics

I’m participating in a webinar with IneoQuest on Thursday, March 31 at 2:00 PM EST as part of their launch of a new product with live, non-referential quality metrics. The bottom line is that if you’re comparing real-time encoders to make a purchase decision, or configuring live encoders you already have, you can gauge the quality in real time, while …

Technical Brief: Switch from CBR to VBR to Improve Overall Quality and Avoid Transient Quality Issues

This article explores the differences between constant bitrate encoding (CBR) and variable bitrate encoding (VBR) and recommends that producers still using CBR should switch to 110% constrained VBR to improve overall quality and avoid transient quali

Five Signs Your Encoding Ladder May Be Obsolete

Your encoding ladder is the set of encoding parameters that you use to create the various files that you deliver adaptively to your web viewers. These encoding parameters can live in your on-premise encoder, in your cloud encoder, or in your online video platform (OVP). When optimally configured, your encoding ladder lets you efficiently deliver great quality video to viewers …

Encoding Brief: The Benefit of B-frames

Executive Summary: B-frames increase compression efficiency, particularly at lower bitrates. However, not all video encoders deliver the requested number of B-frames when encoding using default parameters. Telestream Switch is a software program that identifies B-frames in encoded streams, and computes the overall B-frame percentage. Compressionists seeking the most efficient streams should acquire Switch and test their streams. If B-frames are …

Preliminary Survey Results – CBR, VBR and Capped CRF – $100 Amazon Gift Card Incentive

On January 13th, 2016, I launched a survey to determine the bitrate control techniques most commonly used by streaming producers. Some preliminary results are in, but the number of respondents is too small to draw any conclusions. I wanted to publish the data to stimulate additional interest, and also announce that I am sweetening the pot with a $100 Amazon gift …
