Do you notice a difference if you encode using your GPU vs CPU? I've heard people say NVENC doesn't encode as efficiently as x265 but I haven't actually tried it out.

NVENC can obviously encode much faster, but for archive I'd probably prefer a better compression ratio if thats on the cards.

I use “slow” GPU encoding. I optimized my pipeline for minimal quality loss, not maximum file size savings. I wouldn’t recommend using consumer grade CPUs to reencode because to get a reasonable speed you’ll need to use “fast” presets which tank the quality. Anecdotally fast CPU method saves closer to 60-70% file size.
