I help streaming and video technology companies solve complex technical and market-facing problems in practical business terms. Engagements range from fixed-scope audits and codec strategy reviews to product testing and technical content that helps customers, prospects, and internal teams connect technical performance to business outcomes. 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.
