Hello Rigaya. All good with you ?
Thanks very much for making Nvencc.
The command "--bref-mode" is related with b frame reference pyramid ?
Have a nice week =)

Yes, I think that NVENC’s B-frame reference mode is the NVENC-side control corresponding to B-pyramid.

• disabled
  B frame is not used for reference.
• each
  Each B-frame will be used for reference.
• middle
  Only(Number of B-frame)/2 th B-frame will be used for reference.
