Looking at the defaults:
https://f3kdb.readthedocs.io/en/latest/u...parameters
keep_tv_range is by default: false
see: https://f3kdb.readthedocs.io/en/latest/u...p-tv-range
will adjust grainY and grainC
as a side note: when using Vapoursynth I wrote the code a bit different so that 'keep_tv_range' will always be set to false if the input clip is PC scale and only be used evaluated if the input is TV scale.
