Replicate the input video as perfectly as possible, given
the constraints set by the maximum bandwidth and the video dimensions
128k Dual ISDN
This is the primary audience for dual-line ISDN. Although
DSL lines and cable modems are replacing ISDN use in many countries,
this audience can act as a substream for higher-bandwidth encodings.
12k Substream for 28k Dial-Up
This audience is used as a substream for the 28k Dial-up audience.
You can include it, along with the 16k Substream for 28k Dial-up,
when encoding a SureStream clip for modem users.
150k LAN

as a corporate intranet. This is the lowest-speed audience that
uses stereo music for video soundtracks, and that can encode
more than 15 frames of video per second.

Offers high fidelity downloads, with improved audio quality
over the 750k Surround Stereo (VBR) audience.
256k DSL or Cable
This audience targets 256 Kbps DSL and cable modem users.
This is typically the lowest speed at which these services are
offered.

350k Multichannel (VBR)
This is the lowest-speed audience that preserves multichannel
audio data.
350k Surround Stereo (VBR)
This is the lowest-speed audience offering stereo surround
encoding
384 DSL or Cable
This audience targets 384 Kbps DSL and cable modem users.
It provides the highest-quality, audio-only encoding for a general
streaming audience. Higher-speed audiences improve the video
and audio-with-video quality, but will have the same audio-only
quality.
450k VBR Download

the 350k Download (VBR) audience. Higher-speed audiences improve
the video quality but not the audio quality.

the 350k Multichannel (VBR) audience. Its higher bandwidth improves
video quality only.

(VBR) audience.
512k DSL or Cable
This audience targets 512 Kbps (one-half Megabit) DSL and
cable modem users. The music-with-video quality is better than
the 384k DSL or Cable audience, but the audio-only quality is
the same.
56k Dial-Up
The 56 Kbps dial-up audience is the primary audience
for users connecting to the Internet on 56 Kbps modems. This
audience setting encodes stereo music for an audio-only clip.
Lower-bandwidth substreams, such as the 26k Substream for 56k

user is listening to a stereo music clip, a drop in bandwidth
causes a shift to mono music.

Provides very high-quality playback for large
video clips
5M Multichannel (VBR)
