Non Adaptive – this filter is the most effective for still pictures. Noise
reduction can be set to the highest level with the luma and chroma NR and
threshold controls to produce the best results. Not recommended for pictures
with any motion.
•
Luma – the luma channel can be adjusted independently of the chroma channel for
noise reduction and motion threshold while in any of the Motion Adaptive
Recursive modes. These controls are best set using a waveform monitor and setting
the Show Noise function in the Bypass menu below.
•
Chroma – the noise reduction and threshold of the chroma channel can be
adjusted independently of the luma channel with these controls. A Luma Tie
setting is provided that controls the chroma filter based on the motion estimation
on the luma channel. Not only is noise more effectively reduced when this control is
active, but it can also reduce the appearance of cross-color artifacts from poor
upstream decoding of composite signals.
•
Bypass – set the DNR output mode with this control. You may use this control to
split the screen for comparing noise reduction or detail enhancement. Refer to the
Output menu for more details on setting this mode.
