558 20. Creating Video Output

The Audio Settings pane contains the
encoding options that will be used for the audio
stream of your video file. The basic rule of
thumb is that a higher Bitrate and Frequency
will result in better sounding audio but a larger
video. Again, the defaults here should work for
most all users.

Multiplexing is used during decoding of the
MPEG video and is another feature that should
not be adjusted unless you know precisely what
it does.

Click on Ok when you have made the changes
you want. Those changes will be applied to the
video during rendering.

Compression Options for Flash Video, Ogg Theora, MPEG4,
and Windows Media
When you are creating any of the stream-friendly video formats you will
find that the Compression options are all the same. You have a series of
settings for certain bandwidth connections, starting with 5 megabit and
going down to 56k modem.

These Compression methods control the overall quality level of the video.
The speeds listed are indicating the amount of data that the video must
stream to the PC to play correctly. The video will look better when it has
more data that it can stream.
If you click on the Settings button for each of these entries you will see the
data transfer rate in kilobits per second. Higher numbers translate to better
looking videos. If you want to specify your own transfer rating for both the
video and audio streams you can select Custom as the Compression
option.
