Defines and displays the output quality in terms of video bit rate. A
default video bit rate is preselected by a calculation. The default bit
rate provides you good quality.
In order to adjust the quality individually, you can move the slider.
Note: The higher the required aspect ratio, the higher the needed bit
rate. Therefore, parts of the quality slider may be grayed out, if the
required aspect ratio would result in a bit rate which is not supported
by the selected encoder or technically impossible.
Only available when the check box Fit to target is cleared.
Displays the bit rate of the output in Kbps. The bit rate is the quantity
of data transmitted within a time unit.
The value is determined by the output settings you have selected
and is updated in real-time to any made change.
Defines what kind of bit rate the audio codec is using.
Constant bit rate (CBR): Specifies a constant bit rate, i.e., the data
flow per unit of time and thus the quantity of the saved data is the
same over the entire audio file.
Variable bit rate (VBR): Specifies a variable bit rate, i.e., the data
flow per unit of time and thus the quantity of the saved data adapts to
the dynamics of the audio file. The bit rate, for example, can be
lowered at quieter points in the track.
Average bit rate (ABR): Specifies an average bit rate, i.e., the data
flow per unit of time and thus the quantity of the saved data adapts to
the dynamics of the audio file but the average bit rate tends to the
defined value. In principle is it a variable bit rate with a limited bit
band width and thus combining the advantages of the variable and
the constant bit rate.
