Encoder: NVIDIA h264/265 export

Hi,
Is the NVIDIA encoder only available for 10xx Nvidia cards or higher?
The speed of rendering is dramatically higher than Native encoder - 4 to 6 times faster from my experience. My friend/colleague editor has a 970 card at the Nvidia encoder isn't present for him (Resolve Studio).

should actually be available with all Nvidia cards that have CUDA.
However, it seems to be that if you select H265 with 10Bit this is still faulty, since it then breaks off and an error message comes with Unknown error.
I have a Titan X (Maxwell series)

I haven't installed these and I have the Nvidia encoder option.

You don't have to, you can see which codecs are supported with which cards.
Maxwell only supports upto 8 bits 4k h.265, Pascal supports upto 10 bits 8k h.265.

My GTX 980Ti renders H265 very fast with Resolve 15.22 Studio!!!

Even my GTX1060/6 renders HD video to H264/H265 at about 200fps in Resolve Studio using the NVENC option. I'm very impressed.
It does slow a little with heavy grading or effects but fortunately I usually only have minor grading on most of my footage.

NVIDIA uses separate circuitry for encoding and decoding as opposed to using CUDA cores for that.

Hi,
it seems to me that you are talking about NVIDIA H265 encoding support on MAC Systems !
I cannot find any NVIDIA H265 encoding support on my Win Studio Version 15.2.2 although I have
a GTX 1080.

I am on Win 10 with 1070 card. My colleague is with a 970 card. He doesn't have the Nvidia option as in the screenshot.
This is for both h264 and 265.

In the past, encoding with NVIDIA NVENC was fast but the quality was bad. (in general, not speaking about Resolve) Has it improved now with latest cards and h265? Or is it still optimized for fast encoding?

Dwaine,
thanks for the reply.
I have the Windows Studio Version.

I cannot find any H265 NVIDIA encoding support.

Send a link to a Resolve diagnostics log (Resolve Help menu - Create Diagnostics Log on Desktop) and a Windows System Information .NFO file.

The hardware encoding/decoding are under two different menus:
Decoding - Under general preferences and has its own tab
Encoding - This is in the deliver page and not the preferences that you took a screenshot of

In the mean time I updated my Video Driver from 388.13 to the latest NVIDIA Driver 417.35.
And now H265 is showing up as a choice.
Thanks for your answers.
Sorry ...

here is the result of my first try to render H265 in main10 profile.

Is it dying after about 65k frames or something like that (43m41s for 25p timelines)?

It is dying after ca. 21Minutes 50 seconds export of 2160p50 timeline with main10 profile.
4,78 GB stream size.
BTW: I generated a "DaVinci-Resolve-logs-20181218-145035.zip" but don't know how to attach it.

Problem solved
It is unbelievable - the Problem is the NVIDIA Driver.
After going back to Desktop Driver 399.24 and checking the "Network Optimization" box the rendering process comes to the end - without interruption.

Why unbelievable? Encoding is done on GPU, so this is not surprise at all.
These sort fo problems will keep appearing all the time.
The only way is to test and lock drivers to specific version, but users won't respect requirement anyway as they like to have latest version (which is quite often not the best at all).

Andrew,
agreed - but where is the description from BMD works with 399.24 ?

To use rendering via NVIDIA h.264 option I need to buy a Studio version right?

Recently, I bought DR Studio 16 but the encoder option wasnt there...
Yes I do know my hardware is old but many user with the same machine can export with nvidia aceleration. Do you have any idea?
Intel i7 920 quad core 2,67 Gz
24 Gb Ram
Nvidia 1050
Windows 10 home 64 Bit
Thanks!

The NVIDIA 1050 should support it, so the next guess would be the NVIDIA driver is not up to date.

Then the next guess would be that, even though you've bought the Studio license, you haven't installed the Studio version of Resolve.
If you could provide Resolve logs and detailed system info, that could remove some of the guess work...
In a File Explorer window, go to:
C:\Program Files\Blackmagic Design\DaVinci Resolve
and run CaptureLogs
This will place a Resolve log file named similar to this on your Windows desktop: DaVinci-Resolve-logs-20181228_140434.zip (You may not see the .zip extension if your system is set to hide known extensions).
Then open Windows System Information and do a File - Save (Not a File Export), which will generate a .NFO file.
Place both those files on a file sharing site and provide links to the files here.

Thanks Dwaine for your support, I think the .nfo File wont help you because it is in German. But i can tell you that 1 hour ago I´ve uninstalled and reinstalled DR and Nvidia drivers and it didnt work.

The GPU also needs more than 3.5GB of VRAM to do HW accelerated encode.

This is a Resolve imposed restriction. If we use up too much VRAM for h265 encoding, then you will have problems with Resolve processing.

Dear Rohit,
I have a 1060 GTX 3GB and I know this is too small for h.265 encoding(HW) in R16. But if I could put another same vga next to the old one, so I'll have 2x3 GB VRAM, that will be enough for smooth run for Resolve 16 and encoding in h.265? Or one 6 GB VRAM card alone is much better than double two?
Thanks your answer in advance!

GPU RAM doesn't add up. If you ave 2 cards with 3GB then Resolve sees 3GB, not 6.
This is why you should never use 1 GPU with a lot of RAM+ another with low amount as you will be capped to lower value.

OK! Thanks! And what is the advantage of two VGA, in one PC?

If both, not either, but both GPUs are capable of handling the required processing, then DR will distribute a few frames to one GPU and another few frames to the other GPU and the processing will complete a little bit faster.

Generally that is true but I am not sure that is the case for encoding.
First of all the NVIDIA hardware encoding is a separate circuitry from CUDA but also in cases of long GOP encoding or perhaps even generally, it is all but certain if two or more GPUs work in tandem on encoding.
