Caution
The noise reducing function in
the DNS-3901-S provides
impulse and recursive filtering.
When the Noise Reduction
function is enabled and active,
increasing the
IIR_Threshold
and Motion_Threshold
parameter setting can affect the
quality of the output video.
Using a live program source,
you must experiment and find
the appropriate setting to
balance between the amount of
noise reduction and picture
impairments due to the filtering
processes.
