I only have one P4000 in my server and it does decent... I have 3 GPU slots open. Link to comment Share on other sites More sharing options...
BAlGaInTl 279 Posted January 14, 2020 Author Share Posted January 14, 2020 Is hardware transcoding actually happening? Sure seems like it. I'm not great at reading logs, but I'll attach a couple below. The dashboard says NVENC is being used. https://www.ebay.com/itm/1U-Supermicro-6-bay-Server-Mining-2-GPU-SLOT-1017GR-TF-Xeon-E5-2620-V2-64GB-Ram/133183361630?epid=141689379&hash=item1f0258d25e:g:m8QAAOSwAk5di6uo Then get one or two Quadro RTX 4000 GPU's and call it a day lol.

The dashboard says NVENC is being used. A 1070 Ti should be able to handle a single transcode without any issue I would think. And if you applied a reasonable or lower than the original 4K bitrate do you see a difference as you are converting 265 to 264 at almost 140Mb. This conversion between the two codecs doubles the bitrate, so if the device is set to max bitrate 140Mb and your HEVC media has a bitrate of 70Mb, you end up with a h264 of 140Mb. To me this chart would suggest what you are seeing. https://www.elpamsoft.com/?p=Plex-Hardware-Transcoding Edited January 14, 2020 by Happy2Play 1 Link to comment Share on other sites More sharing options...

That's the issue i'm finding with my p4000 I need to get one of the RTX's It does decent with regular HD movies though...

I think this files are 10 bit and/or HEVC. Link to comment Share on other sites More sharing options...

Looks like it should actually. https://developer.nvidia.com/video-encode-decode-gpu-support-matrix Sent from my iPhone using Tapatalk 1 Link to comment Share on other sites More sharing options...

Most main stream HDR or 4k stuff is 4:2:0 Edited January 14, 2020 by Doofus Link to comment Share on other sites More sharing options...

Guest asrequested Posted January 14, 2020 Share Posted January 14, 2020 What does the 4:2:0 represent? Chroma sub-sampling. 4:2:0 is standard, then 4:2:2 and 4:4:4 is the highest, when you can't use RGB10. https://www.rtings.com/tv/learn/chroma-subsampling 1 Link to comment Share on other sites More sharing options...
