It can create video streams for distribution via [[Microsoft Silverlight]]. This utility is created to record the screen for various purposes such as [[YouTube]], [[Twitch (service)|Twitch]] etc.

== 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:<ref name=nrfaq>{{Cite web|url=http://www.microsoft.com/expression/products/FAQ.aspx?key=encoder|title=Frequently Asked Questions|work=microsoft.com|publisher=[[Microsoft]]|archiveurl=https://web.archive.org/web/20121214000917/http://www.microsoft.com/expression/products/EncoderPro_FAQ.aspx|archivedate=December 14, 2012 }}</ref><ref name=comparison>{{cite web|title=Expression Encoder 4 Pro Overview|url=http://www.microsoft.com/expression/products/EncoderPro_Overview.aspx|website=microsoft.com|publisher=[[Microsoft]]|archiveurl=https://web.archive.org/web/20121213172851/http://www.microsoft.com/expression/products/EncoderPro_Overview.aspx|archivedate=December 13, 2012 }}</ref>
#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]].

== History ==
Version 1.0 was released to manufacturing on September 6, 2007.

A beta of version 2.0 was released in March 2008 which included new VC-1 codecs (Advanced, Main, and Simple profiles) and better Silverlight support. Version 2 was [[Software release life cycle#RTM|released to manufacturing]] in May 2008. Expression The first [[service pack]] added [[H.264]]+[[Advanced Audio Coding|AAC]] encoding support for devices. According to Microsoft, Expression Encoder 2 was not a replacement for [[Windows Media Encoder]], despite having many similarities.<ref>{{cite web | url=http://www.microsoft.com/expression/products/FAQ.aspx?key=encoder | title=Frequently Asked Questions | publisher=[[Microsoft]] | work=microsoft.com | accessdate=June 27, 2009 | quote=''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. | archive-date=December 14, 2012 | archive-url=https://web.archive.org/web/20121214000917/http://www.microsoft.com/expression/products/EncoderPro_FAQ.aspx | url-status=live }}</ref>

Expression Encoder 3 added multi-channel audio output, more built-in device profiles, like support for [[Zune HD]], [[Xbox 360]] and [[iPod Touch]], as well as profiles for online services such as [[Facebook]] and [[YouTube]]. It also added Expression Encoder 3 Screen Capture, which allows users to create video screen captures.

Version 4 added IIS live smooth streaming, screen capture improvements and an H.264 encoder based on the [[MainConcept]] SDK.<ref>{{cite web | url=http://blogs.iis.net/alexzam/archive/2010/06/25/now-available-expression-encoder-4-iis-media-services-4-0-beta-ssme-1-0-smf-2-0-rc1-olympics-case-studies.aspx | title=Expression Studio 4 launch–Blend, Web, Encoder, Design | publisher=[[Microsoft]] | work=Alex Zambelli's Silverlight Media Blog | first=Alex | last=Zambelli | access-date=September 26, 2010 | archive-date=June 28, 2010 | archive-url=https://web.archive.org/web/20100628153833/http://blogs.iis.net/alexzam/archive/2010/06/25/now-available-expression-encoder-4-iis-media-services-4-0-beta-ssme-1-0-smf-2-0-rc1-olympics-case-studies.aspx | url-status=live }}</ref> Expression Encoder 4.0 SP1 was released in January 2011 and added [[CUDA]]-enabled GPU-assisted encoding, [[High-Efficiency Advanced Audio Coding|HE-AAC]], screen captures as a live source, live broadcasting templates, Selective Blend de-interlacing and other features.<ref>{{cite web | url=http://blogs.msdn.com/b/expressionencoder/archive/2011/01/28/10121701.aspx | title=Expression Encoder 4 SP1 released! | publisher=[[Microsoft]] | work=Expression Encoder blog | first=Jamie | last=Lang | access-date=July 12, 2011 | archive-date=July 29, 2011 | archive-url=https://web.archive.org/web/20110729003757/http://blogs.msdn.com/b/expressionencoder/archive/2011/01/28/10121701.aspx | url-status=live }}</ref> Service Pack 2 (SP2) with about 300 bugs fixes was released on November 2, 2011, and added new features such GPU-accelerated video encoding and the removal of 10 minutes screen recording limit.<ref name="4-sp2">{{cite web | url=http://www.microsoft.com/download/en/details.aspx?id=27870 | title=Microsoft Expression Encoder 4 with Service Pack 2 (SP2) | publisher=[[Microsoft]] | work=Download Center | date=January 28, 2011 | accessdate=December 2, 2011 | archive-date=November 26, 2011 | archive-url=https://web.archive.org/web/20111126202906/http://www.microsoft.com/download/en/details.aspx?id=27870 | url-status=live }}</ref><ref name="4-sp2-blog">{{cite web | url=http://blogs.msdn.com/b/expressionencoder/archive/2011/11/02/10233201.aspx | title=Expression Encoder 4 SP2 released! | publisher=[[Microsoft]] | work=Expression Encoder blog | date=November 2, 2011 | accessdate=March 9, 2012 | archive-date=March 16, 2012 | archive-url=https://web.archive.org/web/20120316040453/http://blogs.msdn.com/b/expressionencoder/archive/2011/11/02/10233201.aspx | url-status=live }}</ref>
