Windows Media Audio Settings

The following table describes options available when you select Windows Media from the

Windows Media menu in the Export Settings dialog box and then select an audio track.

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. This option defines the quality of the video profile setting.

Quality Choose Constrained or Unconstrained. Choose Constrained when playing either locally

or on a device that has a constrained reading speed, such as a CD or DVD player.

Bit Rate Defines the size of the data stream in megabits per second.

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.

Quality Values for this option range from 0 to 100, with 100 being the highest quality.

Keyframe Defines the number of keyframes used as part of the encoding sequence. The value is the

number of keyframes used for every second of video. A lower number results in higher

quality, but larger files.

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 1384.

Uncompressed When this option is selected, your Avid editing application creates a high-quality export

in which no picture information is lost. This option does not compress the file and can

result in very large files.
