8.4.3.3
Vertical
Vertical controls aliasing in down-converted content.
•
Level:
Specifies the enhancer strength.
•
Soft 1–2:
Provides attenuation in the frequency band specified.
•
Normal:
Nominally flat frequency response.
•
Sharp 1–2:
Applies more boost in the frequency band specified.
•
Frequency Band:
Specifies the frequency band to which enhancement is applied.

8.4.4 Noise Reduction
The Noise Reduction controls enable you to reduce levels of noise and grain.
8.4.4.1
Enable
The Enable check box is the master enable for all noise reduction processing.
8.4.4.2
Recursive
To achieve noise reduction, Recursive applies a temporal recursive filter to both luminance
and chrominance picture content. To avoid blurring moving objects, the filter includes motion
detection and adaptation which disables the filter when significant motion is present.
The Luma and Chroma controls set the maximum noise reduction (0 = Off). You can set the
sensitivity of motion detection either automatically with Auto mode, or manually with the
Threshold slider.
•
Luma:
Adjusts the noise reduction applied to the luminance signal. The adjustment
range is 0 to 7. The preset value is 0.
•
Chroma:
Adjusts the noise reduction applied to the chrominance signal. The
adjustment range is 0 to 7. The preset value is 0.
•
Mode:
Choose between automatic or manual filtering.
In Auto mode, the background noise level is measured and the threshold set to give a
good compromise between noise reduction and motion blur. In Manual mode,
increasing the Threshold value allows for pictures with higher background noise.
Note: For best results in Manual mode, always set the threshold to the lowest value
for the desired noise reduction.
•
Threshold:
Adjusts the noise reduction threshold. The adjustment range is 0 to 7.
The preset value is 0.
