Does supporting the nvenc 4:4:4 format even have any advantage? Does it
support encoding something non-4:2:0? If not, then the first option is
probably preferable for now.
With sufficiently new hardware it does. It will output h.264 or hevc
with 4:4:4 by default

Apparently swscale decides that any kind of 12 or 16 bit content, even
if 4:2:0, whould be converted to YUV444P16 instead of do
