Okay, yeah UHD 730. To troubleshoot this, we need someone with the UHD 770 or Intel Iris XE on 11th -13th gen NUCs. I’m curious how you were able to reproduce this previously.
On your AV1 machine, with the sample I provided, which players did you test with? This question makes a difference because the quality issues with the above mentioned iGPUs only impacts quality on the plex web player. I can watch the same content on my Samsung TV app (with subtitles disabled), and through my Roku stick, without issue while transcoding. The issue here is not the source content.
