Aye Wahyu,

Try this workflow and let me know any questions please. You will see the analyzed vmaf value in the status monitor or webinterface when the job has finished.

He Wahyu,

for example:
imagine a workflow where you compress a Master-File (e.g. DNxHR or ProRES HW) to H264 or H265. With this node you can compare the original with the compressed files. The result for VMAF (The "Netflix-Algo") <20 poor > 40 fair, >60 ok >80 good and up to 100 excellent, no visible difference.

And as often I see now, that emcodem is way ahead and faster with responding to this question....
anyway, hope it helps ;-)

regards
thomas
