Overview
Expression Encoder is a transcoding and linear video editing program. It features a graphical user interface based on Windows Presentation Foundation (WPF) as well as a command line interface. It can export videos to H.264 or VC-1 formats or prepare video streams for distribution via Microsoft Silverlight. It supports Silverlight player controls and Silverlight templates.
Microsoft Expression Encoder is available in different editions:
- Pro edition, the full-featured commercial incarnation of the product is available through retail or volume licensing outlets as well as the BizSpark program.
- Pro edition without codecs, which lacks royalty-incurring codecs and is available to DreamSpark, WebsiteSpark or MSDN subscribers. This version does not support H.264 or Advanced Audio Coding (AAC) formats in its output, nor can it open AVCHD, MPEG-2 and Dolby Digital (AC-3) formats.
- Express edition is free of charge but feature-limited. This version has the same restrictions as the Pro edition without codecs, but also does not support live streaming.
