Alternates and Audiences options for encoding

In the Export Settings dialog box, specifying a streaming media codec in RealMedia or Windows Media formats enables Audiences options, while QuickTime streaming media codecs enable a similar set of Alternates options. Both allow you to output variations of a movie suited to different network speeds. The player software associated with the format detects and selects the most appropriate version to ensure smooth playback. For example, Windows Media includes Audiences such as Dial‑up Modems (56 Kbps) and Broadband Or Cable Modem/DSL (384 Kbps). Whereas QuickTime generates individual movies suited for each export type, RealMedia and Windows Media generate a single movie that stores the variations.

Note: Some codec-specific settings are not documented here. For more detailed information regarding a particular codec, check the documentation provided by its developer.
