Selur's Little Message Board - not working nvenc ffmpeg

I solve my problem that was typed here before. I just delete Cover.jpg in attached in mkv.
For now, not working nvenc ffmpeg,

And i have question, how to keep or improve grain on videos? What parametres i should take ?

The data you provided doesn't help at all, read sticky.
Also note that nvenc ffmpeg is marked experimental, Hybrid does not check any settings there. So if you use a feature combination that isn't supported by your hardware ffmpeg will crash.
-> On Windows better use NVEncC.

Okay, i get it. Thanks.

I found nvencC in program folder also in config-tools. How i need activate this to encode?

Hybrid allows to use it in case:

Code:
NVEncC.exe --check-features

reports that your card can be used.

Maybe im dummy, where to text it?

Hybrid comes with NCEncC.exe in it's 64bit folder.
So if you want to see the same as Hybrid you would need to call something like

Code:
c:\Programs\Hybrid\64bit\NVEncC.exe --check-features

inside a 'Windows Command Prompt'.
My guess is that there is a problem with your driver<>hardware combination.

NVEncC has a bunch of 'Information Options':

Code:
Information Options: 

-h,-? --help                    print help

-v,--version                    print version info

   --check-device               show DeviceId for GPUs available on system

   --check-hw [<int>]           check NVEnc codecs for specified DeviceId

                                  if unset, will check DeviceId #0

   --check-features [<int>]     check for NVEnc Features for specified DeviceId

                                  if unset, will check DeviceId #0

   --check-environment          check for Environment Info

   --check-avversion            show dll version

   --check-codecs               show codecs available

   --check-encoders             show audio encoders available

   --check-decoders             show audio decoders available

   --check-formats              show in/out formats available

   --check-protocols            show in/out protocols available

   --check-filters              show filters available

Er... Yes I did it right. But problem is window open and... closes i cannot read or do anything. Undecided

You didn't open a command prompt and executed the command.
Your just executed the command.
There is a difference.
