when the 8520 DNR submodule is installed:
•
Mode – set the mode of noise reduction based on the type of noise and the amount
of motion in the signal. Set the Mode to one of the following:
Automatic Lo – this setting is completely automatic and requires no user
adjustments. The adjustments for Noise Reduction (NR) and Threshold
change depending on the source material. Luma and Chroma filters and
Chroma/Luma tie controls are shown in the figure below. This mode uses
the Impulse 1 filter that removes a moderate amount of noise and shows
little motion artifacts. It is most useful for signals that vary a great deal
and require less operator intervention.
Automatic Hi – this setting is also completely automatic and requires no
user adjustments. The adjustments for enhanced noise reduction (NR) and
Threshold. Luma and Chroma filters and Chroma/Luma tie are on. This
mode uses the Impulse 2 filter (also temporal). All noise is removed in this
mode and chances are higher for motion artifacts to appear.
