4k Settings

4k movies and their limitations

This is for Plex only for Emby go here: EMBY Settings

At Cosy Club (Cosy Plex), streaming 4k requires a compatible 4k device, and Plex app.

Transcoding of 4k is not allowed as this requires a lot of server resources, due to this, 4k is only meant to be “Direct played” to prevent resource starvation on the servers and allow you the best quality.

Why would anyone transcode it down to 1080p anyways?

 

So in order for you to direct play 4k, your device must meet basic requirements;

  • The device must support HEVC (Video codec)
  • The device must support the chosen audio codec (AC3, DTS, TrueHD or similar)
    • In most cases, a movie or tv show will have multiple audio tracks. If your device doesnt support one track or the other, it will transcode, try changing the audio track to something your device supports
  • The internet connection of your device, should exceed 150mbps (in most cases)
  • The device must be configured for maximum quality streaming within the plex app
  • If you use subtitles, the device must natively support the subtitle format

Whether 4k will work for you (and the amount of “work” you must put in, in order to make 4k work on your device) will vary depending on your setup, the staff at Cosy Club therefore CANNOT assist with questions such as “How do i direct play 4k movies“.

Using 4k on plex requires some knowledge of both Plex, the 4k media and your device – We expect that you, the customer, know or, figure out, how to use 4k on your setup yourself.

If you try to transcode 4k, you will experience the following symptoms

  1. Your stream will crash, with the message “You are not allowed to transcode 4K content, fix your settings! or “The transcoder has exited due to an error”
  2. Your stream will never start, and spin endlessly trying to load.
  3. If trying to use unsupported subtitles it will either crash or not start.
  4. Note I have the servers set up to kick any 4k transcoding, so do check your settings!

How to debug why your device is transcoding

  1. Re-check your Plex Settings in Settings, Video Quality, Remote Streaming, Set to Maximum.
  2. Re-check your Plex Settings in Settings, Video Quality, Adjust Automatically, deactivate/uncheck.
