Every other way I've encountered is no different than a 1-pass encode.
How can you get NVENC to read a stats file? I must have missed that parameter.

But, even if it could, running the first pass on the CPU kinda' defeats the purpose (speed) of NVENCC.

Right now all NVENCC can do is a 2-pass within a short range of frames... which isn't really a 2 pass. Honestly, though, I'm pretty satisfied with the output quality of 1 pass anyhow, and the CQM output looks really good.
