Subtitle

Lists one subtitle of the selected video item. By clicking on the button

you can see all available audio tracks and you can also select / deselect

audio tracks for the selected video item.

Only available for DVD-Video.

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.

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, but

output quality is lower. If the bit rate is high, more data is transferred.

The file size is then large, but the output quality is high. A value of 128 is

near CD quality.

The values available are determined by the audio format you have

selected.

Quality

Defines the quality level if VBR is used for bit rate mode. You can set the

variable bit rate between 0 and 100. 0 means the lowest, 100 the highest

quality.

Compression

Defines the compression rate for lossless codecs.

Sampling rate

Selects the scan rate. The scan rate is the frequency that a signal is

scanned per time interval.
