Blurred grain.

[anton_foy]

Hello!

When I use addgrain, would it be possible somehow to blur only the grain while leaving the image/footage unblurred?

Using MaskTools, you could do like
o = last
g = o .mt_lut( Y=-128 )
g = g .AddGrain( your, values ) .blur( here )

mt_makediff( o, g, U=2,V=2 )

Could be done without MaskTools as well, just with Avisynth's internal filters. But those use a different "neutral" point of grey for differences, and frankly, I always forget if it's off by -2 or +2 ... ;)

Thank you very much Didee, I will try it right away :)
