The separation line for the side-by-side comparison will also appear on the active output
video. This setting should be used with care, and only during the setup process
and not during a live broadcast.
This menu item controls the various levels of noise reduction to apply to the
video signal. The different levels will set the motion detection threshold and
the aggressiveness of the filters to remove noise.
When the control is set to Off, there is no noise reduction. The input video
is left untouched.
When the control is set to Light, the noise reducer will have a lower motion
detection threshold and a less aggressive filter.
reduction is used for video that has low random noise, where removal of
low-level details is minimized.
When the control is set to Medium, the noise reducer will have an average
threshold set for the motion detection threshold and aggressive filters. This
level of noise reduction is used for video that has typical amounts of random
noise, where the module will remove random noise and affect low-level
details, more so than a Light setting.
When the control is set to Heavy, the noise reducer will have a high motion
detection threshold and a very aggressive filter.
reduction is used for video that has high level of random noise, where the
filters will remove the random noise, but will soften the low-level details.
Note: Setting the value higher than needed to remove the noise present,
will over-soften areas of low amplitude, fine details.
Note: Setting the value too low may cause the circuitry to leave random
noise that it could remove. However, removal of low-level details will be
minimized.
This control allows the user to compare the input video before noise
reduction (left-hand side) and after noise reduction (right-hand side).
