Default Parameter Description

Default Parameter Values on the Tuning Page

Figure 1 GUI for 3DNR parameter settings

3DNR consists of NRy for luminance noise reduction and NRc for color noise reduction. NRy contains four levels of NR functions in series. Assume that the four levels are numbered as 0, 1, 2, and 3. For the filters with the same number and type at different levels, their effects vary due to the differences in implementation and serial connection effects.

Levels 0 and 3 have spatial filters with temporal assistance, while levels 1 and 2 have both temporal and spatial filters. The chrominance filters are independent of the luminance filters. For details, see Figure 2.

Figure 2 Classification of 3DNR parameters by the filter level

X in nX** and mX** indicates a level n. For example, n0sf2 indicates the parameter of level 0 in nXsf2 series parameters, and m1id0 indicates the parameter of level 1 in mXid0 series parameters.

[en] indicates that the denoising function at this level is enabled. The value 0 indicates that this function is disabled, and the value 1 indicates that this function is enabled. Parameters in red are not recommended for changing.

The level-3 spatial filter parameters nXsf5, dzsf5, nXsf6, nXsfr6, nXsbr6, nXsfn, nXsth, nXsthd, and sfr have two sets of interfaces (as indicated by 3a and 3b in the figure). These interfaces are used for the motion region (3a) and static region (3b) to implement different processing effects. To enable level 3, level 2 and the temporal reference must be enabled. Otherwise, level 3 has no actual effect.
