This file was optimized by Plex, using the setting “original quality”.
However when playing the file on my Win10 laptop, it stops regularly every few seconds and then it carries on , subtitles and quality are fine.
I tried turning on and off the hw transcoding, but it does not make any difference, since the stream is “Direct Play” to the my laptop.
The server RAM and CPU resources are <30%, the connection is 1gbit LAN for the server and 1600ac wifi for the laptop.
Before you shoot me, mine is just a test, going forward I have no intention of using 4K source materials, but I am testing the infrastructure so I need something heavy.
I am a bit confused by that. If you created an “optimized version” of the file, did you make sure that you are actually playing this version?
What does the media info say about the average bitrate of this optimized version?
Don’t even try to keep an optimized version at 4K resolution. An average bandwidth of 56 Mbps (which means there will be peaks in the bitrate much higher) will max out almost every device.
If you create optimized versions, only go up to 1080p.
HEVC was created for 4K, so use that for 4K (i.e. if you want to watch 4K, use your original file. It is perfectly fine at 11 mbps for 4K).
