‘in_range’
‘out_range’

     Set in/output YCbCr sample range.

     This allows the autodetected value to be overridden as well as 
allows forcing a specific value used for the output and encoder. If not 
specified, the range depends on the pixel format. Possible values:

     ‘auto’

         Choose automatically.
     ‘jpeg/full/pc’

         Set full range (0-255 in case of 8-bit luma).
     ‘mpeg/tv’

         Set "MPEG" range (16-235 in case of 8-bit luma).


Haven't tried it, one possible issue is that if ffmpeg is auto inserting 
a filter that you can't override it.

Use -loglevel debug when testing to see what's going on

There may be no problem in this case WRT auto inserted filter, I am just 
recalling having problems with -target pal-dvd and filters ages ago.
