Windows Media Encoder
|Stable release||9.0 / January 7, 2003|
|Operating system||Microsoft Windows|
|Type||Video and audio encoding software|
Windows Media Encoder is a freely downloadable and free-of-charge media encoder developed by Microsoft which enables content developers to convert or capture both live and prerecorded audio, video, and computer screen images to Windows Media formats for live and on-demand delivery. It is the successor of NetShow Encoder. As of January 2013[update] it was still available for download. The download page reports that it is not supported under Windows 7. WME has been replaced by a free version of Microsoft Expression Encoder. The Media 8 Encoding Utility is still listed. WME was available in both 32-bit and 64-bit versions.
The latest version, Windows Media Encoder 9 Series, can encode video using Windows Media Video version 7, 8 or 9. Audio encoding uses a number of Windows Media Audio version 9.2 or version 10 (if the version 10 codecs are installed) profiles and a Windows Media Audio 9 Voice speech codec. Content can also be created as uncompressed audio or video.
Windows Media Encoder 9 Series enables two-pass encoding to optimize quality for on-demand (streamed or download-and-play) content. It also supports variable bitrate (VBR) encoding for download-and-play scenarios. True VBR can be applied over the entire duration of a high-motion sequence, ensuring the highest quality. This version also enables scripted encoding with the wmcmd.vbs VBScript file allowing content developers to encode large numbers of prerecorded media files. Bundled with the program are the applications Windows Media File Editor, Windows Media Profile Editor, and Windows Media Stream Editor.
The GUI encoder application is actually a "wrapper" of the encoder itself. Developers can write their own applications using Visual Studio to perform the same functions found in the application. These applications can be used to automate audio and video production. An SDK is also available.
