You are scaling, which is deinterlacing, anyhow.  Since you
aren't scaling to exactly half-height, the output is going to look
very, very bad.  You're also trying to use denoise3d and pp=de on the
video, which won't work correctly on interlaced video.

If you want to keep the interlacing, don't crop or scale vertically at
all, add "il=d:d" at the beginning of your filters, "il=i:i" at the end
of your filters, and add "ildct:ilme" to your lavcopts.

If you use it for encoding, it will waste lots of bits, and usually
decrease the quality.  If you're playing this back on something other
than a computer, I can understand why you'd want to use pp before
encoding, but it may make things look worse.
