I thought to share my experience with the 4k recordings.
This is my set up to play all my recordings from my drone (and not only):
Instead of shield any device capable of running plex server.
So… I upload my videos to the NAS and plex gets the directory of the folders. The beauty of the plex is transcoding, in this way I can play my videos anywhere on any device with plex client available.
If you interested please let me know and I would be happy to answer all questions how this is done.
