I’m not able to PM you the log files as I don’t see a way to send you a private message.
I checked a little bit further and noticed that for the movie I had trouble with, 2 versions of the movie were available in plex: one UHD, one for streaming around 10Mbps.
(Plex always chooses this version even on LAN but that’s another story).
The issue is only happening with this optimized version so it might be a problem with the way the source file is encoded. I don’t have any artefact using the older transcoder thought. If you want to investigate, I have a log zip ready to be sent privately.
