As you can see in this video, version 11 of the tool adds several new features, including support for the VMAF 4K model, data rate graphs, and…
Demuxed is the annual conference for video engineers by video engineers.

I have a confession to make. Though I’ve attended dozens of Streaming Media conferences, I’ve never attended a kickoff session. Not, of course, because the content wasn’t information and insightful, but because I’m always scurrying about trying to finish my own presentations. This dubious accomplishment ends at Streaming Media West next month, when Roger Pantos,…
