Measuring Video Quality Using AVQT
AVQT, short for Advanced Video Quality Tool, is a macOS based command line tool which estimates perceptual video quality of compressed videos that might contain video coding and scaling artifacts. Utilizing the AVFoundation framework, AVQT supports a wide range of video formats, codecs, resolutions and frame-rates in both the SDR and HDR domains, which results in easy and efficient workflows — for example, no requirement to decode to a raw pixel format. AVQT uses Metal to achieve high processing speeds by offloading heavy pixel-level computation to the GPU, typically analyzing videos in excess of real-time video frame rates. In this talk, we’ll cover key attributes of AVQT which make it useful across applications. We’ll also demo how to use the tool and interpret the obtained scores correctly.
