Noise Reduction Option
3
This option enables the noise reduction feature to be switched on (at
different levels) or off. The feature can be used when the incoming picture
material is corrupted by high frequency noise (such as white noise). When
noise reduction is enabled, the Encoder applies sophisticated edge
preserving filters on the incoming material and removes the noise which
can reduce the encoding difficulty considerably.
To access the Noise Reduction option, press the Noise Reduction softkey
from the Video Source Menu.
The three levels of noise reduction are in increasing order of noise
reduction capability. They are independent of video content. All three
settings are noise-level adaptive, i.e. it is not necessary to change the
setting for different noise levels.
Once a level has been selected it can be left enabled. When a clean source
is used the noise reduction dynamically switches off and then back on
when noise is present. Refer to Application Note ST.AN.1094, Video Noise
Reduction and Compression for more information.

Noise reduction is only available when software option M2/ESO2/NR is purchased.
