multiple bit-rate mpg > could you elaborate on how to create a multiple bit-rate mpg video? Our video guys use Windows Media Encoder for this regularly. You can encode to single- or multi-bitrate files using the WME application, or automate it through the WME automation API. We do both. Download the docs & SDK here (tons of info): http://msdn.microsoft.com/downloads/default.asp?URL=/code/sample.asp?url =/msdn-files/027/000/960/msdncompositedoc.xml A multi-bitrate file is like an onion -- layers of encoded data. A streaming server and player together can determine a connection's bandwidth dynamically, and stream the appropriate portion of the file. The bandwidth is monitored continually, and the server can in/decrease the quality of the video by streaming a portion of the file that has a higher/lower bitrate. This is called "intelligent streaming", and it requires that you make a single .asf file that contains multiple streams, each one being encoded at a different bitrate. Fire up WME, start a custom encoding session, fill in the encoding parameters, and click OK. There are pre-fab MBR profiles in the PROFILE section of the NEW SESSION dialog, but you can make your own with the Profile Manager. Hope this helps Rob
