)

2D NR
The threshold is used to suppress noise, the higher the level is, the smaller the
noise becomes, and the image appears more blurry then before.
Grade
NR level ranges from 1 to 16. Default value is 8.
3D NR
This threshold is mainly for multi-frame (at least 2) image processing. It reduces
noise with info between a frame and previous frame. The higher the value, the
better NR will be. Default is enabled.
Grade
NR level ranges from 1 to 16. Default value is 8.
