Comment (by Brainiarc7):
You can attempt interlaced encoding on NVENC provided that:
(a). You're using an NVENC-capable GPU older than Turing. Turing GPUs
inexplicably disabled interlaced encoding.
(b). The following flags are set before input:
{{{-flags +ildct+ilme}}}.
Alternatively (or in combination with the above), insert the filter
{{{-vf tinterlace=interleave_top,fieldorder=tff}}} and retest.
