Encoder Profile

Profiles are rather complex and include a number of parameters that interact with one
another, so it is generally best to use the pre-defined profiles. Only change a profile if
completely familiar with all the configuration options.
To change a profile, select it by clicking its tab and then change the parameters within that
profile.
If a setting outside the permitted range for a parameter is entered, the nearest valid value is
substituted when the settings are saved.
Profile name
If required, enter a new name for the profile.

Bit rate optimization
The bit rate optimization defines the optimization strength. These must be combined with the
appropriate scene mode. The Bit rate optimization and Maximum bit rate work in a quality-
driven mode. The encoder generates a bit rate up to the maximum setting if the scene
requires it.
For maximum image quality, apply minimum bit rate reduction (Maximum quality). This will
also greatly increase the file size. If maximum bit rate reduction is applied, the image will have
less quality, but the file size decreases significantly (Minimum bit rate).
Select the necessary bit rate optimization setting:

Maximum bit rate
The encoder does not exceed the maximum bit rate set, which limits the image quality when
necessary. Use the Averaging period to stabilize the maximum bit rate.
The Target bit rate is managed only when the Averaging period is set. If the value entered is
too low, it will be adjusted automatically.
This value is not the network transmission bit rate.
Averaging period
Select the appropriate averaging period as a means of stabilizing the long term bit rate.
Target bit rate
To optimize use of the bandwidth in the network, limit the data rate for the device. The target
data rate should be set according to the desired picture quality for typical scenes with no
excessive motion.
For complex images or frequent changes of image content due to frequent movements, this
limit can temporarily be exceeded up to the value entered in the Maximum bit rate field.
The target bitrate will be the average bitrate over the averaging period.
