4K transcoding problem with NVENC (outdated false limitation in Hybrid)

[Selur]

I tried to reproduce this with my 1070ti, by:

• Starting Hybrid
  
• Loading a 4k source
  
• Selecting NVEnc as encoder (Base->Processing->Video->NVEnc)
  
• Settings 'NVEnc->Base->Encoding mode' to 'constant quantizer'
  Command line looks like this:
  
  NVEnc --y4m -i - --fps 25.000 --codec h264 --profile high --level auto --sar 1:1 --lookahead 16 --cqp 20:23:25 --gop-len 0 --bframes 3 --ref 3 --mv-precision Q-pel --cabac --deblock --preset default --videoformat undef --colorprim bt2020 --transfer smpte2084 --colormatrix bt2020nc --output "E:\Temp\4K sun HDR test.264"
• Setting an output file (Base->Output file)
  
• Creating a new job (Base->Add to queue)
  
• Starting the job (Jobs->Queue->Start)
  

-> Encoding worked fine.

Only options that could be possible to limit the max MBs per second are the profile&level settings.
Other than that I got no clue what settings you used.
My current guess is that you used a profile&level combination which doesn't allow the bitrate+fps+resolution combination you chose.

Please, read the 'Infos needed to fix&reproduce bugs,..'-sticky before you post about a problem.

Without proper detail there is no way for me to reproduce the issue.
