NvEnc Intra Frame QCP HEVC encoding

Hi everyone,

I saw that Adobe introduced Nvidia hardware decode for HEVC and h.264 in Adobe Premiere, so I thought I would see how effective it is on the timeline. Not too bad, but still laggy - presumably because any given frame I access will have to access more than the current frame to re-constitute it.

With that in mind, I used Handbrake x265 with keyint=1 to encode some 4K60 footage and was surprised at how fast it was on the Premiere timeline. Faster than ProRes, CineForm, anything.

With that in mind, I'd like to archive my 4K footage in this format, and I'd like to do it in a speedy fashion, hence NvEnc. I can't seem to make Handbrake encode intra-only, but the encoder definitely supports it. Can anyone recommend a tool that can do it, and how to do it? ffmpeg should be able to do it in theory, but I couldn't get a working command line. A GUI would make things a lot simpler.
