movie is compressed in two passes in order to optimally use the bandwidth for
highly-compressed movies for the Internet.
Bit rate/quality/audio format: The bit rate is decisive in defining the
display/audio quality. The higher this is set, the better the videos will look and
the larger the files and the required encoding time will be. For variable bit rates,
the bit rate is adapted dynamically to the requirements of the corresponding
picture or sound material. Either the quality value may be set between 1-100
or, for two-pass encoding, an average or maximum bit rate. For audio, the bit
rate is set additionally by the audio format.
Import: For the most common applications (other than for playback on mobile
devices, for which you should use the supplied presets) like Internet streaming,
Microsoft provides diverse system profiles to choose from. If you have the
Windows Media Encoder 9 installed, which is available from Microsoft as a free
download, you can edit the profiles or create your own. These may be loaded
by pressing the "Import" button.
"Clip info" enables the title and artist names, copyright details, and
descriptions to be entered.

Video as MPEG-4 video
MPEG-4 is the most advanced video format available at the moment. Unlike
other formats, this provides very high-quality pictures at the same file size. The
presets list is correspondingly long. We recommend looking through this list for
settings for each application and corresponding device.
MPEG-4 refers to a highly complex "academic" standard that operates and is
supported variably according to make. To go into detail on these differences
and parameters would be beyond the scope of this documentation. For this
reason, indications, along with the operational manual of your device, are given
that should help create executable MPEG-4 files. For more experimental users,
the complete setup options of the MPEG-4 codec can be found behind the
"Advanced settings..." buttons.
Video/audio: MPEG-4 and the newer MPEG-4 H.264 are currently available,
and these are used with new devices especially. MPEG-4 video may be
combined with AAC or AMR sound (the latter is mainly for mobile telephones).
The combination of MPEG-4 H.264/AAC is more seldom applicable (Apple
iPod Video). MPEG-4 H.264 featuring AMR will almost never occur.
