11.2.7 AVC Encoder
The AVC (Advanced Video Encoding) entry and its subentries can be used to make AVC
encoding settings for your data.
11.2.7.1
Thread Count
Nero Recode supports multi-core processors. If you have one of these, you can distribute
the encoding process to the required number of threads.
The Thread Count drop-down list allows you to choose whether to allow the encoding
process to be performed by several threads. This means that you can use a multi-core
processor system to optimum effect.
The number of processor cores used corresponds to the number of threads you have
selected.
11.2.8 Bitrate mode
The Bitrate mode entry can be used to make settings in relation to the bit rate mode and
quantization (see
Encoding mode).
11.2.9 General settings
The General Settings entry is used to make settings for the Decision Quality, the Motion
Vectors and the GOP Properties.
These setting options are only available if you have selected Nero Digital AVC in the Nero
Digital category.
11.2.10 Decision quality
The Decision Quality control indicates the required quality of the output file in relation to the
time expended.
High Quality produces the best quality with the longest encoding period.
High Speed requires the shortest encoding period with the poorest possible quality.
We recommend a medium value in the Best range.

Motion vectors
See Maximum MV range .
11.2.10.2
GOP properties

from which a P or B-Frame may draw its information.
If B-Frames are permitted, the number must be at least 2.
