UM-2014.1-07
A high setting (e.g. Wide) is suitable for larger grain/noise and/or more
pronounced variations in amplitudes.
Setting spike to Narrow in conjunction with setting Motion Sensitivity
to High and Motion Estimation (in the Processing screen) to Best
can help avoid motion estimation errors caused by noisy / grainy
material.
Pos/Neg Profile
The Pos/Neg profile allows the user to select the amount of noise reduction
(both spatial and temporal) applied to the highlights or lowlights within the
image.
This function is important when dealing with grainy images in positive
or negative film stock.Positive film will generally show more grain in
the lowlights whilst Negative film will generally show more noise in
the highlights.
Neg
Values :
Positive,Negative
Default :
Positive
Parameters :
Positive - more grain reduction in lowlights
Negative - more grain reduction in highlights (Film mode)
Having selected the mode, you need to set the Pos/Neg Trim level on the
Processing screen. This will adjust the noise reduction levels equally for all
RGB channels in highlights (Neg) or lowlights (Pos).
