In the first article in this series, Baby Steps with Apple’s Advanced Video Quality Tool and Quality Metric, I detailed what Apple’s Advanced Video Quality Tool (AVQT) is and how to use it. In this article, I tested multiple video files with Apple AVQT and describe my user experience. In the next article, I’ll review how AVQT scoring compares to VMAF and SSIMPLUS on a very limited test set.
Working with AVQT was not the smoothest road I’ve ever traveled, but some of that was the author’s failure to RTFM (read the freaking manual) and part of it an obscure but avoidable quirk in AVFoundation. I reached out to Apple on both issues and they quickly helped me resolve them.
