VMAF is a tool developed by Netflix to grade the quality of a compressed video file in comparison to the Original. However, VMAF is only available through the commandline or as an extension to FFMPEG. If you're like me, you find the functionality of VMAF very useful but very time consuming and confusing to use at first. This tool I have built simply adds a gui to the program to make it easy to use.
Using visual studio Just click the .sln file then compile for your system. In the folder with your binaries, you'll have to provide your own copy of ffmpeg, vmaf, and the model files for ffmpeg in a subfolder named model. I couldn't figure out how to get VMAF to output the score to stdout so currently the score is only available through the generated log.txt when the program is run.
