Passes (not available
when you select
Uncompressed)
Defines the number of encoding passes, either 1 or 2. With 1 Pass encoding, the content
passes through the encoder once, and compression is applied as the content is
encountered. With 2 Pass encoding, the content is analyzed during the first pass, and
then encoded in the second pass based on the data gathered in the first pass. 2 Pass
encoding might result in better quality but takes longer.
VBR (not available
when you select
Uncompressed)
Variable Bit Rate. When you select this option, the formats available are VBR formats. If
you deselect this option, the formats available are CBR formats.
Format (These
options change when
you select VBR.)
You can encode audio and video content at either a constant bit rate (CBR) or a variable
bit rate (VBR). Use CBR if you plan to stream the content. Use VBR when you plan to
distribute the content for downloading and playing either locally or on a device that has a
constrained reading speed such as a CD or DVD player. Choose from one of the format
options.
Buffer Size Defines the number of seconds that you want content to be stored before encoding
begins. A larger buffer results in better quality content, but requires more memory. When
you encode content, the encoding process is delayed by the amount of time specified in
the buffer. The content is also delayed by the same amount of time when streaming to a
player.
Language Select from the list of available languages.
Option Description
Use Marks, Use
Enabled Tracks
See “Use Marks and Use Enabled Tracks Options” on page 1323.
Mono
Stereo
Use this option to export audio tracks in either mono or stereo.
Sample Rate Defines an audio sample rate, either Project rate, 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, or
96 kHz.
You can use this option if your sequence has a mix of sample rates and you need to create
a single sample rate. (You set the project rate in the Audio Project Settings dialog box. For
more information, see “Audio Project Settings for Capture” on page 168.) You can also use
this option to change the sample rate if the application to which you are exporting does not
support the current sample rate.
Bit Depth Defines the bit depth, either Project bit depth, 16 bit, or 24 bit.
