NOTE: If you apply noise reduction and make color adjustments within the same node,
noise reduction is processed first, followed by color adjustments.
Using Noise Reduction Controls with the DaVinci Control Panel
All three Noise Reduction controls are available via knobs on the PRIMARIES, NOISE
REDUCTION control group on the Center panel.
To open the Noise Reduction controls on the DaVinci control panel:
Press the PRIMARIES or MAIN soft key on the Center panel, whichever is visible
(depending on which control group is currently displayed).
Motion Blur
Motion Blur settings use optical-flow based motion estimation to add artificial motion blur to
clips that have none. This can be useful in cases where a program was shot using a fast shutter
speed, and you later decide that the resulting video has too much strobing. By analyzing the
motion within a clip, the Motion Blur settings can selectively apply blurring to the image based
on the speed and direction of each moving element within the scene.
Motion Blur controls
Three parameters let you set how much motion blur to add, and at what quality:
Motion Est. Type: A setting of Better provides more accurate pixel mapping at the
expense of being more processor intensive. Faster provides a more approximate result,
but is less processor intensive.
Motion Range: Determines what speed of motion to consider when defining regions
being blurred.
Motion Blur: Raise this parameter to add more motion blur to the image, lower it to add
less. The range is 0–100, where 0 applies no motion blur, and 100 applies maximum
motion blur.
The Blur Palette
The Blur palette has three different modes of operationblur, sharpen, and mist. While the
functionality of the Blur and Sharpen modes somewhat overlap, each mode provides dedicated
controls that the other ones lack.
As with virtually everything else in the Color page, the operations performed in the Blur palette
can be limited as a secondary operation using HSL Qualifiers, Windows, or Imported mattes,
which makes it easy to apply these effects to specific portions of the image.
Many of the controls in the Blur palette consist of three ganged sliders, one for red, one for
green, and one for blue.
