I have downloaded several 4K HDR videos from the internet and loaded them into PLEX. These are super high res videos (3800X?) with bold colors and interesting typically on 8K, 12K and 16K channels. They play no problem within YouTube, but PLEX (more likely my media server) cannot handle them without choking/lagging every 30 seconds.
Can this be fixed? Is my media player inadequate? I use Gigabit Fiber, and have 550+ mb Wifi service in my house. What are your thoughts?
video resolution is one thing… the used codecs/formats for video/audio/subtitles as well as average/peak bitrates will probably matter even more.
if the client cannot handle that particular combination as-is, your Plex Media Server will attempt to transcode the files on-the-fly – the same is true if your home network doesn’t have the bandwidth to accommodate the required bitrate (keep in mind that WiFi is highly depending on your environment and bandwidth will be impacted by anything from walls, furniture, other equipment, distance, neighboring WiFis…). The more complex the video, the more horsepower your server will need. Transcoding 4K, 12K or 16K channels will most likely be above your average server’s capability to transcode on-the-fly.
Without knowing the exact file and server/client specs, we are just guessing. Link?
You might need to add a video card to do the transcoding or your Plex devices you are using is not compatible. Best thing is to use like an nvidia shield or an amazon fire stick… Roku TV or Roku sticks is junk when using with Plex.
I am using a TCL Roku TV and a Sony with an outboard Roku Ultra. Neither will play a high res 8k/12k/16k video file through PLEX. Both will play these files when accessed directly via YouTube.
By the way, for those readers considering the purchase of a TCL TV, don’t. Mine is not yet 3 years old and the screen shows green and purple discoloring which cannot be fixed.
When you play something like that on Youtube you are getting an already processed stream so it plays on your TV. There’s no “on the fly conversion” necessary on your end or theirs
When you play it yourself, you are relying on your hardware to lower the resolution or bitrate
That tv or a Roku is limited to 100mbps max
