With the removal of Windows Media DRM in the Windows 10 Anniversary Update, Windows Media Encoder 9 is no longer compatible with the current version of Windows as of May 2017.
These applications can be used to automate audio and video production. Developers can write their own applications using Visual Studio to perform the same functions found in the application. The GUI encoder application is actually a "wrapper" of the encoder itself. Bundled with the program are the applications Windows Media File Editor, Windows Media Profile Editor, and Windows Media Stream Editor. This version also enables scripted encoding with the wmcmd.vbs VBScript file allowing content developers to encode large numbers of prerecorded media files. True VBR can be applied over the entire duration of a high-motion sequence, ensuring the highest quality. It also supports variable bitrate (VBR) encoding for download-and-play scenarios. Windows Media Encoder 9 enables two-pass encoding to optimize quality for on-demand ( streamed or download-and-play) content.
Content can also be created as uncompressed audio or video. 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. Windows Media Encoder 9 can encode video using Windows Media Video version 7, 8 or 9. WME was available in both 32-bit and 64-bit versions. The Media 8 Encoding Utility is still listed.
WME has been replaced by a free version of Microsoft Expression Encoder.
The download page reports that it is not supported on Windows 7. Windows Media Encoder ( WME) is a discontinued, freeware 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.
