Microsoft Expression Encoder[1] (formerly Expression Media Encoder) is a Windows-based program for encoding digital video for Silverlight-based web video. Expression Encoder can be used to create video compressed VC-1 as well as H.264 for distribution via Microsoft Silverlight. Expression Encoder features a WPF-based modern graphical user interface as well as a command line interface. It supports Silverlight player controls and Silverlight templates.
Microsoft Expression Encoder is available in two different editions: Retail edition, which is the full-featured commercial incarnation of the product and Express edition, which is a free of charge but feature-limited version.[2]
According to Microsoft, Expression Encoder is not a replacement for Windows Media Encoder, despite having many similarities.[3]
