Use
2, ie double original size (and then uses CShift, fWidth, & fHeight to correct the image center shift and output correct downscale size).
In other words, nnedi3_rpow2(2, ...) to double size and then downscale. (original script would quadruple size, and then down scale which would be slower than necessary and maybe not as good qual [methinks]).
No idea about the rest of script, I gorra get a bit more into the hi bit stuff.
EDIT: Some stuff about src_left,src_top removed.
