Defrag Tools #150 – Media eXperience Analyzer part 2: Video Playback Power Saving | Defrag Tools


In this episode of Defrag Tools, Chad Beeder is joined by Jorge Novillo and Jose Baldner. We look at some of the technologies introduced in recent Windows versions to reduce power consumption and improve battery life during video playback on newer hardware, and use Media eXperience Analyzer (MXA) to see whether they are working.

Media eXperience Analyzer (formerly WindowsXRay) is a tool used to visualize ETW traces, with a particular emphasis on media scenarios such as audio/video capture and playback.
