Windows Media
Windows Media Technologies is the Microsoft streaming-media architecture. Windows Media
only supports realtime streaming using a Windows Media Server, which is included as part of
Windows 2000 Server and Windows XP Pro Server. Macintosh users can view Windows Media
files with the Macintosh Windows Media Player, which is available for download at
http://www.microsoft.com/windows/windowsmedia/
Intelligent Streaming cannot be encoded on the Macintosh platform. You can encode only one
video track and one audio track.
Cleaner encodes with Windows Media Video V7 and Windows Media MPEG-4 Video V3 for
cross-platform viewers.
The current release of Windows Media for Macintosh is version 9.
Windows Media formats
Earlier versions of Windows Media Technologies used the Advanced Streaming Format (ASF)
to encode streaming files for the Internet. Windows Media Player contains numerous
enhancements, including improved video and audio quality, as well as support for metadata,
closed captions and URL links.
Windows Media Video
Windows Media Video (.wmv) is a subset of ASF that uses a specific set of parameters,
including the latest codecs, for the delivery of video over a network.
You can create Windows Media Video files by choosing one of the settings under Windows
Media Video in the Settings window.
Note:
Windows Media Video files require an audio track. If you want to create a video-only file,
you can set the volume for the audio track to zero.
Windows Media Audio
Windows Media Audio (.wma) is essentially a Windows Media Video file without the video
tracks. Windows Media Audio is positioned by Microsoft as an alternative to MP3 for
high-quality Web music. The use of the WMA extension enables these audio-only files to be
distinguished by audio players as audio files instead of Windows Media Video files.
You can create Windows Media Audio files by selecting one of the settings under Windows
Media Audio in the Settings window. If the source file contains both video and audio, the video
track won’t be encoded.
