8.1.2 Setting options
Click the Encoder settings tab to specify the settings for the respective
track.
Track:
The encoder settings apply jointly for all
the created tracks.
Track selection has no relevance,
therefore, for the encoder setting.
Input:
Here you can select which encoder you would like to use for digitalization.
„Encoder 1“ is set by default for DIS-1/S and DIS-1/L.
Bit rate:
The bit rate is a measure of the degree of compression of video data; it thus
has a direct impact on the picture quality of the recording. A low bit rate
stands for a high degree of compression with a relatively small volume of
data but poor picture quality.
A high bit rate stands for a low degree of compression with a relatively
large volume of data and very good picture quality. A bit rate of between 4
and 6 Mbps (megabit per second) is a good compromise between data
volume and picture quality. Most requirements in surveillance systems are
met with the quality of picture thus obtained.
GOP Value:
GOP (Group Of Pictures) is a variable for specifying how pictures are
used to generate the MPEG-2 data flow.
A GOP value of 6 and 15 enables good picture quality with high compression.
A GOP value of 1 denotes a low compression factor and should only be
used for special applications (e.g. multiplex mode).
