I got good 1280 16X9 transcode results for this clip by using my standby:

ffmpeg -i NCIS-trim-2.ts -vf ³fieldmatch=order=tff:combmatch=none,
decimate, fps=fps=24000/1001, scale=1280:-1" -stats -pix_fmt yuv420p -c:v
libx264 -c:a copy -preset slower -tune film -crf 18 -x264opts
keyint=40:bitrate=2100:qpmin=8:qpmax=38:qpstep=4 NCIS-trim-2.detelecine.m4v
