Hello Is there a sense in adding the following filters before seesaw, in order to reduce the grain in a movie? degrainmedian(mode=2) degrainmedian(mode=2) a = last b=a.degrainmedian(mode=1) SeeSaw(a,b, NRlimit=5, NRlimit2=6, Sstr=1.5, Slimit=5, Spower=5, Sdamplo=6, Szp=16) I tried to use only seesaw for improving the sharpness and to remove grain, but it wasn't enough. Thank

You can do so, sure. But the more denoising is done before, the more the SeeSaw principle will be canceled: If the "original" (as delivered to SeeSaw) has been denoised already, then any detail lost at this point can't be recovered by SeeSaw. Usually, one should try to use the unaltered original for "a", and an sufficiently strong denoised clip for "b". Then, various settings of SeeSaw can be adjusted until the result is calm enough: make NRlimit is big enough (too low numbers will apply not enough of the denoising achieved by "b"), lower "bias", raise "SdampLo", use "sootheS" (spatial soothing) in combination with bigger and/or negative values for "sootheT" (negative numbers will do double temporal soothing) Compare: in of a very noisy clip I used the following settings: Code:

Thank you for the answer I'll read the seesaw instruction again and try to change the seesaw's parameters.
