Custom Profile Audio Settings for Windows Media Export
The following table describes options available in Custom Profile Audio Settings.
Buffer Size Type 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 The setting can range from 0 to 100, with 100 being the highest quality.
Keyframe Amount 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
Option Description
Use Marks When Use Marks is selected, the current IN and OUT points in the selected clip or
sequence determine starting and ending frames for the export.
Use Enabled Tracks When Use Enabled Tracks is selected, your Avid editing application uses tracks that are
enabled in the Timeline. To export all the tracks in the sequence, deselect this option.
Uncompressed Select this option for high-quality export in which no picture information is lost. This
option does not compress the file and can result in very large files.
Codec (not available
when you select
Uncompressed.)
Select one of the following codecs:
Windows Media Audio 9.1: Provides improvement in compression over the
Windows Media 8 Audio codec. Supports VBR audio encoding.

Windows Media Audio 9 Voice codec instead.
