Reducing Grain using Noise Reduction
If you want to reduce the grain in your scanned film, you can use DaVinci Resolve's powerful
noise reduction features.
Making small adjustments to the temporal noise reduction is an effective way to start, as that is
all that may be required to reduce the grain in your image. If needed, you can then change the
spatial NR settings until you achieve the quality you are looking for.
Noise reduction controls.
Noise reduction is a powerful tool and can be extremely effective. There are various ways you
can optimize the results, for example by adjusting the number of frames used for temporal NR
processing, or by changing the luma and chroma thresholds independently so you can retain as
much detail in your picture as possible.
Please keep reading this section for more detailed information about all DaVinci Resolve's noise
reduction features and how to use them.
TIP
These images show our recommended default settings for film grain and
noise reduction.
Noise Reduction Settings
Noise reduction settings can be found in the 'motion effects' window of the DaVinci Resolve
'color' page. DaVinci offers temporal and spatial noise reduction, which can be used together
or individually. Temporal noise reduction works by comparing a frame to the frames before and
after it, while spatial noise reduction analyses each frame individually.
In many instances, temporal NR is sufficient to clean up your image. Spatial noise reduction is
useful for reducing noise that temporal NR does not, however it should be applied in small
increments, as aggressive use can affect the resolution of your image.
In this section you can find details about each setting and how to use it.
