Hi ... I want to ask you more experienced how to solve streaming + recording.

My vision is to stream at 1080p at 60 fps + record at 1440p at 60 fps

I'm going through dual pc streaming ...

My streaming PC:
ASRock X570 Taichi
WIN: Windows 10 Pro 64-bit
CPU: Amd Ryzen 9 3951x
GPUs: Msi Geforce 1070 Gaming X 8G 8Gb
RAM: HyperX Predator 16GB DDR4 3333MHz
PSU: Seasonic Focus Plus - 850W
SSD: Samsung SSD 960 EVO (M.2) - 250GB
HDD: Seagate BarraCuda - 2TB
CASE: Be quiet! Silent Base 801
MONITOR1: Acer Nitro VG270Ubmiipx - 27 "LED monitor
MONITOR2: Acer Nitro VG270Ubmiipx - 27 "LED monitor
CPU COLER: Noctua NH-D16 SE-AM4
Creative Sound Blaster ZX
EDITINGCARD: Elgato Game Capture 4K60 Pro

After several tests it seems that there is no problem with streaming or recording or I did not record it, but in OBS Studio in the bottom left, OBS writes me from time to time that the encoder is overloaded whether I think about reducing the demands.

But as I say ... I wouldn't say there would be a problem with the stream or the recording!

My OBS setting is ...
Streaming:
x264
Medium
1080p
60 fps
6k bitrate (I'm not a Twitch partner)

Record:
mkv
Nvenc(new)
CQP
18
performance

Do you think it's okay or would you recommend a different setting?
I'm not sure about the recording settings

The output session here doesn't complete, so there's no summary on performance.

You are experiencing a lot of decoding errors relating to one of your media sources. Not sure if that is contributing to encoding overload, it might.

16:07:50.226: error: Failed to decode frame: Corrupt frame detected
16:07:50.226: error: Additional information: Decode failed. Frame data is corrupted.

If you're getting encoding overload aside from the above decoding error, try changing this:

16:07:39.758: YUV mode: 709/Full

To 709/Partial. You're incurring more load without any improvement in quality; this color space will actually look worse on most people's displays.

Thank you very much for the reaction and for finding someone who is interested in solving my problem.

I enclose a new logfile which contains 6 hours of stream along with recording.

If I understand correctly then the problem is only one single media source?

YUV mode: 709 / Full I changed to YUV mode: 709 / Partial

the log file looks complete there are 2 nvec sessions in but No x264
and TONS of

16:07:45.394: error: Failed to decode frame: Corrupt frame detected
16:07:45.394: error: Additional information: Decode failed. Frame data is corrupted.
16:15:08.233: error: Failed to decode frame: Corrupt frame detected
16:15:08.233: error: Additional information: Keyframe / intra-only frame required to reset decoder state


from a DAMAGED or WRONG setting video source Webcam 1/2 Or the elgato
or a element in your scenes
on the point where the media Hardware loaded the error start i have none of that sources so i can't imagine that
but if your system laggs nonestop on wait "Additional information: Keyframe / intra-only frame required to reset decoder state"
i will understand why the encoder "stucks"

First try to remove that error by remove one by on in new sessions every of the 3 media devices
if the error message stops try record if the "low" missing rate

Are you telling me that the stream is running on Nvenc and video recording too?
If I understood well, the sinks are not great but they are there
