Description
This is an adaptive local noise reduction filter. It uses global variance of the noise, local mean and local variance in a moving grid of specified size. It tries to preserve edges as closely as possible.
- Official documentation: http://www.avisynth.nl/users/vcmohan/DeNoise/DeNoise.html
- For AviSynth+ see modPlus, includes high bit depth colorspace support and 64-bit.

DeNoise()
- Process all frames (sf and ef parameters are omitted):
DeNoise(getvar=false, var=120, evar=160, xgrid=5, ygrid=7)
- Process only frames 35-55:
DeNoise(sf=35, ef=55, clip=false, lx=220, rx=245, ty=322, by=402)
