Bit rate mode
Defines what kind of bit rate Nero Recode 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 media 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 media file. The bit rate, for example, can be low-
ered at quieter points in the track.
Average bit rate (ABR): Specifies an average bit rate, i.e. the data
f
low per unit of time and thus the quantity of the saved data adapts to
the dynamics of the media file but the average bit rate tends to the
defined value. In principle it is a variable bit rate with a limited bit
band width and thus combining the advantages of the variable and
the constant bit rate.
Input field
Bit rate
Displays the bit rate
of the output in Kbps. The bit rate is the quantity
of data transmitted within a time unit.
