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.
You said you used Handbake with keyint=1 in the prior paragraph. This is exactly what that does. Do you mean NvEnc? I can't imagine it doesn't have the ability to do so. And IDR-only encoding is a lot faster as well without interframe encoding. Bitrates are generally way higher as well.
