I don't care about VMAF or PSNR, I care about looking with my eyes. With x265 on veryslow and AV1 on preset 0/1, and the source being a UHD BD I was downscaling to 1080p, AV1 looked worse even while using a higher bitrate than x265. Current AV1 encoders have issues with small details and have issues with dark scenes. People are trying to fix them (see svt-av1-psy, being merged into SVT-AV1 itself) but the problems aren't fixed yet.

Yup, have had the same experience.

>see svt-av1-psy, being merged into SVT-AV1 itself Part of it being merged for now. It is unfortunate this narrative hasn't caught on. Actual quality over VMAF and PSNR. And we haven't had further quality improvement since x265. I do get frustrated every time the topic of codec comes up on HN. But then the other day I only came to realise I did spend ~20 years on Doom9 and Hydrogenaudio I guess I accumulated more knowledge than most.

Well, did your "eyes" care more about fidelity or appeal? https://cloudinary.com/blog/what_to_focus_on_in_image_compression_fidelity_or_appeal https://cloudinary.com/blog/what_to_focus_on_in_image_compre...
