Codec (not available
when you select
Uncompressed.)
Select one of the following codecs:
• Windows Media Audio 9.1: This codec provides improvement in compression over
the Windows Media 8 Audio codec and supports VBR audio encoding.
• ACELP.net: In some instances, the Sipro Labs ACELP codec appears in the list of
codecs, for example, if you import a profile that was created by using Windows
Media Encoder version 7.1. If this occurs, Avid recommends that you use the
Windows Media Audio 9 Voice codec instead.
• Windows Media Audio 9 Voice: This codec provides superior quality for audio
content with a voice emphasis and provides for mixed-mode encoding of voice and
music. It is intended for playback at bit rates at 20 Kbps or lower.
• Windows Media Audio 9.1 Professional: This codec supports a full surround-sound
experience and dynamic range control. It is intended for data rates of 128 to 768
Kbps.
• Windows Media Audio 9.1 Lossless: This codec provides lossless encoding of audio
content. It supports multichannel audio encoding and dynamic range control.
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.
