Moscow State’s Dr. Dmitriy Vatolin Talks Codecs, Metrics, and Video Quality

Dr. Dmitriy Vatolin is the Head of the Moscow State University Graphics and Media Lab and one of my favorite colleagues in the streaming quality space. His group produces the Video Quality Measurement Tool (VQMT) that I use almost every day and publishes many codec studies that compare the latest and greatest with comprehensive, and real-world testing.

Dr. Vatolin was one of the first to discover that VMAF was hackable, and because his group also runs the subjectify.us service, a crowd-sourced subjective evaluation platform, he has unparalleled data regarding how the various video quality metrics correlate with subjective evaluations.

Recently, Dr. Vatolin agreed to be interviewed in Streaming Media Magazine, commenting on a variety of topics, including the accuracy of objective metrics and the status of VMAF hacking. You can read the interview here.
