VN-Matrix 300 • System Conguration 36

Image Quality

The Image Quality controls the spatial compression. A setting of 4 provides a visually lossless
image. A higher setting results in higher compression whilst a lower setting applies a lower
level of compression.
Changes made to this setting will result in a corresponding change in the bit rate for the
encoded stream.

Bit Rate

Enter a value up to a maximum of 300 Mbs to set the limit for the aggregate (total) bit rate
for all data.

Click the Advanced button in the Bandwidth (simple) control area described in the previous
pages to access this sectopm.
The controls in this area provide access to the complete set of image quality and bit rate
tools for the VN-Matrix 300 encoder.
The controls are divided into to two main categories:
zVideo Quality
zBandwidth
Some of the controls that are available in the simple control interface described above are
also present in this area. Where controls are duplicated, the settings will track.
