Collection of VMAF Resources

A colleague asked for some resources relating to VMAF. Rather than answer in an email I thought I would create a post around it. Some of these are from Netflix, most from me (Jan Ozer). I’ve broken the items into three groups; Computing VMAF, Using VMAF, and About VMAF.

I hope you find this collection useful.

Computing VMAF

My default way to compute VMAF is with the Moscow State University Video Quality Measurement Tool. Here’s a video that shows how and the latest improvements in version 12.
