Question / Help obs not letting me stream/record

[WumpusDidNothingWrong]

my log
Hey guys, I just made an account so i could ask for help.
After accidentally posting on the mac support i came here to actually get answers
I just got obs today and whenever I try to record it says
"Starting the output failed. Please check the log for details."
I want to record a video with my friends later so i was hoping if you guys had any answers

So you've got an integrated Intel GPU of indeterminate model, and an Nvidia GT 750M.

19:48:17.163: [NVENC encoder: 'simple_h264_recording'] Failed to open NVENC codec: Unknown error occurred

The GT 750M does not actually support NVENC; this requires cards of the GTX designation. I believe OBS is in error here indicating that your card can support NVENC and the error in the log indicates that you don't actually have NVENC support.

19:58:37.384: [qsv encoder: 'msdk_impl'] Unsupported configurations, parameters, or features (MFX_ERR_UNSUPPORTED)
19:58:37.392: [qsv encoder: 'simple_h264_recording'] qsv failed to load

You're also unable to use QuickSync, althoughI assume this is a driver issue. Depending on what version of the intel graphics driver you have installed, you may need to either update or roll it back.

Otherwise you'll have to select the x264 encoder.

It is not sure if the GT 750M supports nvenc or not. It is not listed in the nvidia nvenc support matrix, but this report says it has a GK107 chip and actually supports nvenc: https://www.notebookcheck.net/NVIDIA-GeForce-GT-750M.90245.0.html
According to the nvidia support matrix, GK107 does have nvenc support.
So I suggest a driver update to the most recent nvidia driver available for that card and see again if nvenc can be accessed. If nvenc can be accessed, it is a better solution than Quicksync.
