VMAF - Video Multi-Method Assessment Fusion

[Sharc]

I can't help you with ffmpeg/libvmaf. However, you may want to make the VMAF analysis with vmafossexec.exe instead.

Thanks for the prompt reply.

i can confirm that vmafossexec.exe works (at least calculation of vmaf scores of above 2K frames succeeds).

i downloaded vmafossexec.exe from Jan Ozer's paper:
https://streaminglearningcenter.com/blogs/installing-and-using-netflix-vmaf-master.html

There is a link where Windows executable are located (incl. vmafossexec.exe) and a small note:
"this executable is not the most current version. To get the most current version, youÂ’ll have to download from Github and compile yourself."

I am using the same version from the same source. Don't know whether a more recent compiled executable exists from somebody.

v2 was just released.

a non-referential quality assessment tool would be more useful I guess since access to the groundtruth (reference) is usually not viable...
like when you need to dynamically adjust the filtering strength depending on the quality of each frame

Something like Av1an + vmaf does on the av1 encoder level?

https://github.com/master-of-zen/Av1an/releases/tag/1.10

From my testing, result size can be 50-80% of compared to usual encode, with great visual quality.

But it needs 40% more encoding time.
