Analysis of information sources in references of the Wikipedia article "Microsoft Expression Encoder" in English language version.
Q. Does Expression Encoder replace Windows Encoder? A. The two products serve different purposes. Windows Media Encoder continues to be a freely available solution for encoding video for live and on-demand scenarios. Expression Encoder 2 is purpose built to enable you to produce rich interactive Silverlight Media Experiences. Expression Encoder 2 also uses the newest VC-1 SDK for better Windows Media quality and faster encoding that the previous technology used by the Windows Media Encoder.
Unfortunately, we don't support exporting anything under WMV9 (also called WMV3), which shipped with XP and above (simply use Baseline or Main).
