7.3.3 Visual Enhancements
The settings in the Visual Quality Level entry use human perception patterns to achieve
better overall quality.
This means, for example, that the quality is better in the middle of the picture than at the ou-
ter edges because the eyes tend to focus on the middle and do not notice slight blurring at
the edge. Because quality is "saved" at the edge, you can either improve overall quality or
achieve greater compression.
This means that you can achieve greater compression without any appreciable loss of qual-
ity.
The following check boxes are available in the Psychovisual enhancement area:
Focal plane
If this check box is enabled, human perception is taken into account
in order to achieve better compression for individual pictures at cer-
tain spots in the video.
Macroblock level
If this check box is enabled, human perception is taken into account
in order to achieve better compression for macroblocks in certain
areas in the picture.

7.3.4 Multithreading
You can configure multithreading settings under the Multithreading entry.
Nero Recode supports multi-core processors. If you have one of these, you can
distribute the encoding process over the desired number of threads.
The following drop-down menu is available:
Number of
threads/slices
Defines whether the encoding process should be performed by mul-
tiple threads (Multithreading
). The number of processor cores used
corresponds to the number of threads you have selected.This en-
sures optimal use of a multi-core processor system. This ensures
optimal use of a multi-core processor system.
