Can it transcode 4k

Kit OP ,

I haven’t tried. The vast majority of my streaming is in the same network and direct play at 1080p. The rest is remote when I’m at work at 480p because I have to use data instead of WiFi.

I’ve heard that the M1 Mac Minis can transcode at 4k but I didn’t want to shell out the cash for it.

tsonfeir ,

They can, but only one stream, and it’s spotty. I’ve got a Synology, and I tried to see if I could run another Plex instance on an M1. It wasn’t as amazing as I had hoped.

Kit OP ,

That’s disappointing. I wonder if the M2 is more capable. Granted at that price point there’s little reason to go Mac instead of Linux or even Windows.

tsonfeir ,

It doesn’t seem that much faster. As much as I love apple, I think you’d get more bang for your buck using a PC with specific hardware geared towards this.

Kit OP ,

Admittedly I was mostly drawn to the clean form factor of the mini stack. It’s just so pretty.

It was a happy bonus that Plex was originally designed for Mac and works flawlessly on Mac hardware.

tsonfeir ,

Oh also, I just found out that Plex doesn’t take advantage of the GPU on the M series as of now, so either wait, or go Intel.

Gurfaild ,

I can’t see the picture, but if the Mac Mini is from late 2018 or newer, the iGPU should be able to transcode 4k video.

Don’t transcode on Plex if you can avoid it. It’s very compute-intensive and it makes your streams look like shit. Convert your videos to nice formats that most people can direct play (like x264 or x265) and turn transcoding off. It’ll keep your hardware running longer, keep your electric bill down, and your streams will look better. Win-win-win-win.

That’s assuming you can afford the storage to store multiple copies of your media.

You can convert most movies to 1080p x265 and it takes up a little over a gigabyte of space. If you’re already hosting 4K movies, why do you give a shit about another gigabyte? If you’re NOT hosting 4K movies, then you have ZERO reason to transcode, just make everything 1080p and call it a day.

Also, transcoding DOES cost you money, your electric bill goes up, even if you don’t track it or care. So spend the extra fifty bucks on a few extra terabytes now rather than spending it over the course of several months transcoding. And if you cut out transcoding, you can run Plex on VERY cheap hardware, so that saves you money too.

Transcoding. Is. Dumb.

But also recoding hundreds of movies you will never potentially watch is a waste of power. (I’m assuming a single user setup where stuff is only watched once in a lifetime in most cases)

Kit OP ,

What’s the best way to convert to 1080p x256?

Handbrake

The problem isn’t 4k vs 1080p. I have a separate library for my 4k items which isn’t accessible remotely.

The problem is twofold:

  1. My uplink speeds suck, so often a 1080p file can’t stream remotely without being transcoded down to 720p.
  2. Almost everything I have is encoded to x265, and many Roku devices don’t support that, thus causing media to be transcoded even locally. (The device I use for 4k stuff does but other TVs in the house currently use devices such don’t)

Also, I’m not just running this on a raspberry pi with a single disc. I have over 1500 movies, and 200 TV series already taking up over 30 terabytes on a RAIDZ2 server. So it’s not just a simple matter of throwing an " extra fifty bucks" at it.

Frankly, with everything that’s running in my home lab, the added electricity in CPU power to transcode is barely a rounding error.

Is it possible for me to arrange things so that nothing ever needs to transcode? Sure, but it would be far more trouble and cost than it’s worth at this time.

Not everyone has the same needs or restrictions.

How bad is your upload speed? Most of my x264 and x265 encodes have a total bitrate of around 1.5-2 Mbps. You can’t stream that without transcoding?

Also, have you LOOKED at transcode quality from the other side? It looks TERRIBLE, and it doesn’t significantly reduce your bitrate. I’m telling you, whatever math Plex does to decide whether or not to transcode is USELESS. I’ve seen it transcode x264 videos (that definitely didn’t need to be transcoded) and send them to friends at a HIGHER bitrate, it’s legit insane.

Do what works for you, but Plex transcoding is a bad “feature” that should be avoided at all costs.

EDIT: I’m far from the only one noticing this, the common wisdom is that Plex clients are telling your server to transcode, even when it’s not necessary, and there’s not much you can do about it other than fully turning transcoding off.

Yeah that’s what I do now but I’m running out of space and would really just like to have those original 4k rips. Those converted files add up fast with 200TB
