depending on the image you are working on. At lower values, the improvement may be
more subtle when compared to the 'better' mode, which is less processor intensive than the
computationally expensive 'enhanced' setting. Additionally, 'enhanced' lets you decouple
the luma and chroma threshold sliders so you can add different noise reduction amounts to
each color component, as the image requires.
Radius
Options include 'large', 'medium', and 'small'. A smaller radius offers greater real-time
performance and can provide good quality when using low luma and chroma threshold values.
However, you may see more aliasing in regions of detail when using low NR threshold values.
Setting 'radius' to be progressively larger results in higher quality within areas of greater visual
detail at high luma and chroma threshold values, at the expense of slower performance. An
NR radius of 'medium' should provide suitable quality for most images when using medium NR
threshold settings. As with many operations, there's an adjustable tradeoff between quality
and speed.

Spatial Threshold Controls

The spatial threshold parameters allow you to control which image characteristics get more or
less noise reduction.
Luma
Lets you determine how much or how little noise reduction to apply to the luma component
of the image. The range is 0–100, where 0 applies no noise reduction at all, and 100 is the
maximum amount. Too high a setting may eliminate fine detail from the image.
Chroma
Lets you determine how much or how little noise reduction to apply to the chroma component
of the image by smoothing out regions of high-frequency noise while attempting to preserve
the sharpness of significant edge details. The range is 0–100, where 0 applies no noise
reduction at all, and 100 is the maximum amount. Too high a setting may eliminate fine color
detail from the image. However, you may find you can raise the chroma threshold higher than
the luma threshold with less noticeable artifacting.
Gang Luma Chroma
Ordinarily, the luma and chroma threshold parameters are ganged together so that adjusting
one adjusts both. However, you can ungang these parameters to adjust different amounts of
noise reduction to each component of the image. For example, if an image softens too much
at a certain level of noise reduction, but you find more color speckling than luma noise, you
can lower the luma threshold to preserve detail while raising the chroma threshold to eliminate
color noise.
Blend
Lets you dissolve between the image as it's being affected by the spatial NR parameters at
0.0 and the image with no noise reduction at 100.0. This parameter lets you easily split the
difference when using aggressive spatial noise reduction.

Global Blend

Blend
Lets you dissolve between the image with no noise reduction at 1.0 and the image with both
spatial NR and temporal NR at their current settings at 0.0.
