set ARGS=-map 0:v -map 0:a:1 -map 0:a:0 -vf 
setparams=range=tv:color_primaries=smpte170m:color_trc=smpte170m:colorspace=smpte170m,separatefields,setdar=16/9 
-c:v libx265 -x265-params crf=18 -c:a copy
ffmpeg -ss 10:37.846 -to 11:09.335 -i "%SOURCE%" %ARGS% "%TARGET%"

It seems to me that if 'setparams' is marking tags in the SOURCE instead of the encoder, it would 
not be in '-vf' and would not require transcoding. It would be a '-bsf:v'. So, I don't know what 
'setparams' does. Apparently nothing.
