I currently have Plex and Radarr. I only ever got 1080p content because that’s all my tv would do. Finally getting a nice new tv and would like to get a few 4K hdr movies to watch. Should I be looking for Bluray2160, Remux, or disk and what will Plex play?
Bluray2160 and use mediainfo to make sure the codecs being used are AVC and AAC in an MP4 container.
If they have a 4K HDR capable TV they can playback HEVC. Does anyone even make x264 2160p releases? And container doesn’t matter either, Plex will remux it for you if necessary.
Would it make sense to set up a second radarr to only do 4K stuff? Or can I have radarr download 4K to a specific folder
It depends on what you want. If you plan on keeping two different libraries in Plex I would also keep two Radarr instances, but if you are going for a combined library you could stick to one and just use a different quality profile for the movies you want to be in 4K.
I do that since I like to have both libraries separate in plex and have duplicates.
1080p for remote streaming and low end devices, 4K for local streaming and approved remote clients only. that minimises the frequency of a forced transcode 4k-1080 stream, when a better looking 1080p native file should have been available.
a second radarr instance lets me manage that separately, but I have them synced to eachother.
Yeah I run 2 instances of sonarr and radarr. It makes updating a bit fucky but works pretty good
AAC is such a stupid codec to use for anything other than 2.0 channel.
5.1 / 7.1 AAC doesn’t work over ARC. Over eARC it need to be decoded to LPCM and then sent out. It doesn’t work with SPDIF.
Both eARC and SPDIF will most likely get downmixed to 2ch.
448 or 640kbps AC3 is perfectly fine and has great compatibility, SPDIF, ARC, eARC. Pretty much all blurays and DVDs will also have a AC3 track.
AVC is H264, not what you want for 4k
