4. Bit Rate and Output type

For 44.1 kHz and 88.2 kHz source files, only one bit rate (1234800) and
output type (.wav) are possible.

With 48 kHz source files for DVD encoding,

Bit rate

is selectable: 1509750

bits (1.5 Mbps) or 754500 (754 kbps).

With 48 kHz source files,

Output Type

is also selectable:

■

DTS wave format .wav (Intel byte order, wav header)

■

DTS padded format .dts (raw file, no wave header, Motorola format,
and zero padding to fill frames)

■

DTS compacted format .cpt (Motorola byte order, zero padding is
removed, timecode is removed but a start time is present). This is the
output type needed for the Apple DVD Studio Pro V3.0.

Wav format is used for music where there is no picture to lock to. Wav is
typically for 5.1 or 6.1 music surround discs. Cpt and DTS formats are used
in DVD authoring. Please refer to

DVD Authoring for DTS

on page 20, to

determine the correct bitstream to use. Typically, a .cpt file is used, because
the DTS format is a padded file that is used in older DVD authoring systems.

Dialog Normalization,

click the arrows to change the setting, if necessary.

3dB rear channel attenuation

is display-only here. This parameter is set in

the Packer. (See step 5 on page 8 for explanation.)

Matrix ES

into standard surround channels - (read-only flag) specifies mixing

of Center Surround into Left and Right Surround.

Phase shift

ES channels — Works only with ES source files, where it allows

for phase shifting of Left and Right Surround by –45¡ prior to addition of
Center Surround channel.

Note:

DTS strongly recommends Phase shift be set ON during 6.1 ES

encoding for film. For music, you may wish to experiment with both settings.
