So, in a nutshell. What is the minimum required nvidia gpu needed to do hevc 4k transcode with hdr tone mapping using windows.
I only need to be able to do 1-2 transcodes.
I dont have any pgs subtitles, as im using sub-zero to automatically download srt’s.
Thanks in advance for any replies.
The card must be able to decode HEVC 10-bit video.
750/950/960 (Maxwell GM206)
1050 Ti or better (Pascal architecture)
A quick forum search lists threads with people using the 960. The 750 & 950 use the same chip.
Many have the 1050 Ti.
You can see the capabilities of each card in the Nvidia Video Encode and Decode GPU Support Matrix
Elpamsoft has additional performance information.
Nvidia limits their GTX cards to three concurrent encodes. Additional encodes will use the CPU, not the GPU. See the Elpamsoft site regarding modified drivers to bypass the limit.
You must also be running the 64-bit version of Plex Media Server. It is needed for hardware accelerated HDR to SDR tonemapping.
So, given that all the other conditions are met(plex pass, 64 bit pms, minimum driver version etc etc)
Then as far as I can tell, i should be able to do 2 sessions of 4k hevc hdr remux transcoded to 1080p sdr(with hardware tonemapping) using a gtx 960 and/or a gtx 1060 ? Or am I mistaken? Is there a bitrate limit on the hevc 4k hdr decoding on these 2 cards?
I can pick up either of those used tomorrow for like 40 usd. And im guessing the 960 would be the better choice since it has 1gb more vram then the 1060-3gb.
Its not that i really transcode that often. All of my users, including my self direct play 95% of the time.
But ive grown tired waiting/hoping/praying for HDR10 TM support on windows with QSV(i have a i5-11600k) and a AMD rx6800 in my computer.
If it wasnt my gaming rig, i would just switch to linux allready and be done with it. Without tonemapping the igp easily handles all of my transcoding needs without breaking a sweat, with TM it cant even do 1 without buffering every 15-20 sec.
I dont need to transcode often enough to bother keeping 2 versions of everything.
So thats why I am looking for the cheapest possible solution to get hevc 4k hdr tm for 1-2 sessions.
Thanks again for any input on this:)
