Noise Reduction

Based on the noise reduction controls in the 'color' page, Resolve FX noise reduction has two
types of GPU-accelerated noise reduction designed to subdue noise in problematic clips. Both
methods of noise reduction can be used separately or together, in varying amounts depending
on the needs of the particular material you're working on.

Temporal NR Controls

The temporal NR controls analyze images across multiple frames to isolate noise from detail.
Motion estimation settings let you exclude moving subjects from this operation to prevent
unwanted motion artifacts.
Frames Either Side
The number of frames on either side of the current frame that you want averaged to separate
detail from the noise. You can choose between 0 and 5 frames. 0 applies no frame averaging;
higher values apply more frame averaging, at the expense of being significantly more
computationally intensive. A higher frame setting may yield a better analysis, but may also yield
unwanted artifacts if there are fast-moving images in the frame. A value of 1 may yield better
results for fast-moving images. If you need to use higher frame values, but see artifacts, you can
also try adjusting the motion threshold to fix the issue.
Motion Est. Type
Picks the method DaVinci Resolve uses to detect motion in the image. The default, 'faster', is
less processor intensive, but less accurate. Choosing 'better' can effectively exclude motion
more accurately, but is more processor intensive. None lets you disable motion estimation
altogether, resulting in the application of temporal NR to the entire image.
Motion Range
Three settings, 'small', 'medium', and 'large', let you set the speed of motion that motion
estimation should expect to exclude. A 'small' setting assumes slow-moving subjects with little
or no motion blur, allowing temporal NR to affect more of the image at a given motion threshold
setting. A 'large' setting assumes fast motion with blur occupying a larger area of the image,
which excludes more of the image from temporal NR at the same motion threshold setting.
Choose the setting that gives you the best compromise between reducing noise and the
introduction of motion artifacts when adjusting the motion threshold parameter.

Temporal Threshold Controls

The temporal threshold parameters allow you to control which image characteristics get more
or less noise reduction.
Luma Threshold
Lets you determine how much or how little temporal NR 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.
