I’m currently looking for a 1520+ or a 920+ (cpu wise the same) as an upgrade from my 216play.
I’ve still got one question which I would like to know befor buying it (mainly because I can’t give the product back after ordering it when it dosen’t have a defect…).
So my question is about transcoding. I’ve got some friends and family members, which have clients like the playstation 4 and obviously can’t direct play 4k or true HD content. I am sharing many 4k files now which are mostly 4K HDR (main10) HEVC with True HD 7.1. Bitrates are 75Mbps or sometimes more. All files are normaly .mkv’s.
Has anybody with a NAS or an other device with the same CPU testet 4k to 1080p transcoding and would like to share the results with me? Or if somebody would test a short file from me with the CPU would be more than great!
Thank you for your really fast answer. I know that hdr to sdr is looking washed out right now and im looking forward to see the tone mapping future.
Yeah many clients would remote play on my server. The connection (client and server side) shouldn’t be a problem as it is working really great with the ds216play - obviously without transcoding.
I also tend to the 1520+ as it has one more bay and one more port for the extension unit from synology. Furthermore i saw the article FAQ 26 allready so I would do the workarround directly.
I’m still hoping the nas will achieve at least 2 4k to 1080p transcodes. That would be awesome. Right now some clients are listening to me and buying a nvidia shield so I wont have more than 3 or 4 clients which would use transcoding.
Hopefully I’m not expecting to much out of the ds1520+.
Tone mapping has been an open request for, Im guessing, about three years now. From what I gathered, its a difficult feature to implement, and its very expensive. I dont think the UHD600 will be able to handle it.
I would not base my purchase decission on transcoding capabilities of HDR media. In fact, I didnt when I recently got a synology myself.
I dont doubt Trumpy when he sais HDR transcoding is coming, but I do not believe it is coming any time soon. And I dont think it ever will be supported by any of the currently sold synologys.
If you are determined to have 4K HDR media on your server, your best bet is to have your users get clients that supports it, and get a fast internet connection yourself. And even that isnt a bulletproof proposition, as clients from time to time will revert to their default setting of playing remote content @ 3mbps 720p, allowing Plex to bastardize your HDR files anyways.
Yeah I have the same oppinion. Still trying to motivate my users so they get a nvidia shield or something simillar as a new client. Hopefully most of them will change… i know some of them wanna get a new tv and im hoping they get something which couls directplay right away (like the sony androis tv’s) ^^.
Still hoping that tone mapping will be supported by the UHD600 but my hopes aren’t that big like you said too.
Btw may I ask you if you had a synology nas before? I’m not quite sure how to move plex to the new nas without loosing my metadata, because I’ve changed many things by hand. Plex would be on a new 2.5" ssd in the new nas. And which nas have u bought?
This is my first Synology. I went with the 1621xs+.
I moved from Windows and I didnt bother moving the metadata. Plex picks better artwork than it used to, and does it blazingly fast now, so I just went the easy route.
Sorry to interrupt you more. I’ve got a 1520+ now and im happy with it, but I’ve got a problem (maybe…).
I’ve tested all my 4K media to transcode down to 1080p (all from 8 up to 20 Mbps) and nothing would even play back…! Now im unsure, if I was expecting to much from the HD600 or if I’ve got a problem. Hopefully its the second one.
What I’ve allready tryed:
Selecting every option at “Transcoder quality” under “Transcoder”.
Selecting every option at “Background transcoding x264 preset” under “Transcoder”
Uncheck “Use hardware acceleration when available” (yes I know this must be on but I still gave it a shot
Uncheck “Use hardware-accelerated video encoding”
Playing it from my mobile phone (direct) is no problem. The network is fast enough. I’ve got the newst Version of the x64 Plex-Install from the downloading site directly. I have tested the transcoding with Google Chrome on Win10, on Android 10 and on the PS4 - nothing worked and bufferd like hell. Hopefully this is a error and not the HD600… I have attached three XML files from three diffrent kinds of 4k files I’ve tested.
Looking forward for your answer and thanks in advance !
I’ve tryed everything to transcode without any subtitles checked. For the audio, I tryed playing it with DTS-HD MA 5.1 not with the TrueHD one. I’ve got some multi-channel setups, but not all my users have them so I mostly have 5.1, True-HD and ACC.
Seems I missed zipping the logs. Sorry for that here you have the logs: (File removed)
I noticed while it was transcoding the files, the CPU was arround 20-40% used.
Uhmm I actually don’t know. Haven’t deleted anything and im the only persone with access to it. I restarted Plex while and redownloaded the whole .zip. Seems that there are some other logs in there right now.
Hope that all are files now which you need since the whole zip is much larger than before. (File removed)
One time with “Convert to 2160p 4K (Maximum)” selected and the other time with “Convert (20 Mbps, 1080p HD)”. It didn’t start after waiting quite a time. Here are the logs: (File removed)
Your actually right about the HW Acceleration. Since I’ve tested it yesterday, I forgot to check " Use hardware-accelerated video encoding" again. So I enabled it again and the file plays (like before) for arround 10 secs after waiting quite a time.
Here are the newst logs:

In the meantime I would like to thank you for your time!
Yeah it took arround 2 minutes to start the vid but it only played like 5-10 secs. So I will try to re-encode one movie or tv show in 4k and see how that works. Do you have a method to re-encode on win10?
