[HELP] What noise is that?

[Selur]

Not sure whether the doc helps:

nsize - Sets the size of the local neighborhood around each pixel that is used by the predictor neural network. Possible settings (x_diameter x y_diameter): 0 - 8x6 1 - 16x6 2 - 32x6 3 - 48x6 4 - 8x4 5 - 16x4 6 - 32x4 For image enlargement it is recommended to use 0 or 4. Larger y_diameter settings will result in sharper output. For deinterlacing larger x_diameter settings will allow connecting lines of smaller slope. However, what setting to use really depends on the amount of aliasing (lost information) in the source. If the source was heavily low-pass filtered before interlacing then aliasing will be low and a large x_diameter setting wont be needed, and vice versa. Default: 6 (int)
