Global Blend; Using Noise Reduction - Blackmagic Design Cintel Manual De Instalación Y Funcionamiento

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 (100.0). This parameter lets
you easily split the difference when using aggressive spatial noise reduction.

Blend: Lets you dissolve between the image with no noise reduction (1.0) and the

image with both spatial NR and temporal NR at their current settings (0.0).

Using Noise Reduction

The following procedure suggests a method of using the noise reduction (NR) parameters to
achieve a controlled result.
Applying noise reduction to an image:
1 Enable temporal NR by choosing 1 to 5 frames from the 'number of frames' menu. Keep
in mind that more frames dramatically increase the render time of this effect, while it
may or may not significantly improve the result, depending on your material.
2 Choose options from the 'motion est. type' and 'motion range' menus corresponding
to how much motion is in the image. If there's a lot of motion, you may need to choose
'better' and 'large'. If there's not very much motion, lesser settings may suffice.
3
With luma and chroma threshold linked, slowly raise either parameter until you just start
to see a reduction in noise within nonmoving areas. Then make smaller adjustments
to determine the maximum amount you can add without creating artifacts or overly
softening detail.
4 If there's obviously more chroma than luma noise in the image, you can disable luma
and chroma linking at a satisfactory level of luma noise reduction, and then raise the
chroma threshold to address color speckling in the picture.
5 Suppose you're not satisfied with the tradeoff between the maximum possible
threshold of noise reduction and the prevention of motion artifacts. In that case, you
may want to adjust the motion threshold setting, lowering it to omit more of the motion
from the noise reduction operation, or raising it to include more motion. If you're still not
satisfied, you can also try better 'motion est. type' and 'motion range' settings.
Keep in mind that the strength of temporal NR is to reduce noise in unmoving parts of
the image. When you've achieved the best tradeoff between noise reduction in the still
areas and avoidance of motion artifacts in the moving areas of the image, it's time to
turn to spatial NR to further eliminate noise throughout the rest of the picture.
6 Enable spatial NR by raising either the luma or chroma threshold parameters, which are
linked by default, until you strike a suitable balance between the reduction of noise and
an unwanted increase in image softness.
7 It's recommended to choose the Enhanced option from the spatial NR mode pop-up,
as it will yield the best possible results. However, this can be processor-intensive,
so if you need better real-time performance, you can switch the mode to Faster and
compare results.
8 If there's obviously more chroma than luma noise in the image, you can disable luma
and chroma linking at a satisfactory level of luma noise reduction, and then raise the
chroma threshold to apply more aggressive spatial NR to address color speckling in
the picture.
