Recoding Video Discs

Nero Recode

Audio & Subtitles window

For recoding DVD-Video or Blu-ray video to video file or to audio file, audio settings are

available for the single audio tracks. You can open the Audio & Subtitles window via the

button. The following options are in general available, depending on the chosen device:

File extension

Defines the audio file extension.

Only available for recoding to audio file.

Codec

Selects the audio codec used for the output audio format.

AC3 and DTS are only available for pass-through!

Bit rate mode

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.

Bit rate

Specifies the bit rate, i.e., the data flow per unit of time and thus the

quantity of the saved data.

If the bit rate is low, less data is transferred. The file is then small,
