Motion Effects Palette
The Motion Effects palette (only available in the Studio version) contains two sets of controls for
applying optical-flow-calculated effects to clips in your program. These include enhanced
Spatial and Temporal noise reduction, and motion-estimated artificial motion blur.
Noise Reduction Controls
Two sets of parameters let you apply GPU-accelerated Temporal and/or Spatial noise reduction
that’s designed to let you subdue noise in problematic clips, in close to real time on
workstations with appropriate processing power. 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. Furthermore, each set of controls is highly customizable, allowing for varying
amounts of noise reduction to the chroma and luma of an image, as well as numerous options
for how to apply this noise reduction.
Noise Reduction and Motion Blur controls
Temporal NR Controls
The Temporal NR controls analyze images across multiple frames in order to isolate noise from
detail. Motion estimation settings let you exclude moving subjects from this operation in order
to prevent unwanted motion artifacts.
 Number of Frames: The number of frames you want DaVinci Resolve to average in
order 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 the higher a value you use. Also,
a higher frame setting will yield a better analysis, but may 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 you 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, with the result being 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
