This server is not powerful enough to convert video

Hi all,

I'm new to Plex and this forum and am hoping someone can offer some help please.

My Plex setup seems to struggle with high definition movies. It will sometimes display an error saying "This server is not powerful enough to convert video".

In my limited knowledge, I thought I had specified a package that was sufficiently powerful so I'm hoping someone might be able to identify what the weak link or the weak setting in my setup is please.

My setup is as follows:
I’m running the Plex App on Apple TV which speaks via Wifi to me Mini Mac which has the Plex Server Software and all the files on a WD 1TB XHDD plugged in via USB 2.0.

The exact specs are as follows:

  • Apple Mac Mini (Late 2010), Core 2 Duo 2.4GHz, 12 GB RAM, 320GB HD
  • Apple TV 4th Gen
  • Sony Bravia 49” 4K Ultra HD Smart TV
  • Western Digital 1TB Elements USB 3.0 2.5" Portable Hard Drive
  • Orange Livebox Wifi Router
  • Speedtest results: 48mbps Download Speed, 28mbps Upload Speed

My gut instincts are as follows:

  • All the hardware is new and all the software up to date, except for the Mac Mini that was second hand- perhaps that is slow because of unknown 'abuse'?
  • Perhaps the Wifi is slow?
  • I'm also confused about how to set the 'Local Video Quality', 'Remote Video Quality' and 'Remote Audio Quality'.

Thanks for your time,

Kind regards,

Nic

    All the hardware in your setup will work. But you failed to say what you are streaming.
    As my signature says.
    I beleive how your media is formatted (size/bit rate/mkv/mp4/codec/subtitles/audio, etc) is a major part of your streaming enjoyment and success!

    Client hardware used or using - Shield 2015 (pro and 16gb) and 2017 pro, ATV4, Xbox 360 and one, Fire stick and TV, windows PMP, Raspberry PI, Roku Stick, 3 and 4 plus several Android Phones and Tablets.

    I give MY opinion from MY experience!

    So much importance is put on the processing power of your PMS box.
    I say equal or more should be put on correctly formatting and optimizing your media !

    Thanks for your help and interest thus far.

    I've noticed the problem with two specific files so far with a 4.21GB mkv and a 1.56GB mkv

    If I can get you any more information please advise me on how to do so, thanks!

    The device you play back media on might be a powerful desktop PC or maybe a mobile phone. These devices are quite different in several important ways.
    Desktop PCs usually:
    Have an extremely powerful processor and so it can process high-resolution files with ease
    Can play a broad array of media encodings (H.264, VC-9, WMV, etc.)
    Is usually attached to a high-resolution display
    Mobile Devices usually:
    Have a low powered, power efficient processor that isn't capable of processing high-resolution files smoothly
    Have a restricted set of media types it can play back (H.264)
    Have a small, lower-resolution integrated display

    Mobile devices are still in their infancy and are not nearly as powerful or flexible as a desktop PC. They have special requirements when it comes to playing back media. Ideally, the media should be sent in:
    The ideal resolution
    The right media encoding (H.264, etc.)
    A compatible file container
