This article refined by gives a complete review on a former Windows media file encoding software well known as Windows Media Encoder. It elaborates on the definition, versions, encoding theory, downloading, installing, as well as using. Since Windows Media Encoder is discontinued by Microsoft, this post recommended an easy-to-use alternative.

What Is Windows Media Encoder?

Windows Media Encoder (WME) is a discontinued free media encoder software developed by Microsoft. It allows content developers to capture or convert prerecorded or live screen images, audio, or videos to Windows Media formats for on-demand and live delivery.

Windows Media Encoder is the successor of NetShow Encoder. Its download page says that it does not support Windows 7. So, there is no Windows Media Encoder for Windows 7.

Now, Windows Media Encoder has been replaced by a free edition of Microsoft Expression Encoder. The Media 8 Encoding Utility is still listed. Windows Media Encoder is available in both 64 bit and 32 bit.

What Is Windows Media Encoder 9 Series?

Windows Media Encoder 9.0 can encode video taking advantage of Windows Media Video (WMV) version 7, 8, or 9. Audio encoding makes use of many Windows Media Audio (WMA) version 9.2 or 10 (if the version 10 codecs are installed) profiles and a Windows Media Audio 9 Voice speech codec. Besides, content can also be created as uncompressed video or audio.

Windows Media Encoder version 9 ensures two-pass encoding to optimize quality for on-demand (download-and-play or streamed) content. Also, Windows Media Encoder supports variable bitrate (VBR) encoding for down-and-play scenarios. The VBR can be used over the entire duration of a high-motion sequence while ensuring the highest quality.

Windows Media Encoder edition 9 also enables scripted encoding with the wmcmd.vbs VBScript file while permitting content developers to encode large numbers of prerecorded media files. Some Windows media programs are bundled with Windows Media Encoder 9 including Windows Media File Editor, Windows Media Profile Editor, as well as Windows Media Stream Editor.

The graphical user interface (GUI) encoder application is a wrapper of the encoder itself. Developers are able to write their apps using Visual Studio to perform the same features found in the program. Those programs can be applied to automate video and audio production. In addition to that, an SDK is also available.

With the removal of the Windows Media Digital Rights Management (WMDRM) service in the anniversary update in Windows 10, Windows Media Encoder 9 is no longer compatible with the later version of Windows since May 2017. Thus, Windows Media Encoder is discontinued by Microsoft.

Versions of Windows Media Encoder

The following are the historical versions of Windows Media Encoder. The Windows Media Encoder latest version is Windows Media Encoder x64 Edition.

  • NetShow Encoder 3.0
  • NetShow Encoder 3.0.1 (comes with PowerPoint 2000)
  • Windows Media Encoder 4.0 (part of the Windows Media Tools)
  • Windows Media Encoder 7.1 (for Windows 98, Windows Me, and Windows 2000)
  • Windows Media Encoder 8.0 Encoding Utility (command-line) for Windows 98, Windows Me, and Windows 2000
  • Windows Media Encoder 9.0
  • Windows Media Encoder x64 Edition (based on Windows Media 10 SDK)

Windows Media Encoder Studio Edition was a separate planned version for Windows Media Encoder 9 with support for segment encoding and multiple audio channels. After Beta 1, it was eventually canceled. Later, Microsoft published the commercial software, Microsoft Expression Encoder as part of its Expression Studio suite.


Windows Media Tools 4.1 was the last release for Windows 95 and Windows NT 4.0.

Windows Media Encoder Process Theory

Typically, an encoder converts uncompressed videos or audio into compressed packets in a format specified by the encoder software. To convert media files into Advanced System Format (ASF), you can rely on Windows Media video and audio codecs.

An encoder is identified by the globally unique identifier (GUID) that represents the category, video or audio. The encoder’s output type is represented by a media type’s major and the sub-type GUID.

The following are the codecs of Windows Media video and audio.

Windows Media Video (WMV) Codecs

  • Major type: MFMediaType_Video
  • SubType: MFVideoFormat_WVC1, MFVideoFormat_WMV3, MFVideoFormat_WMV2, MFVideoFormat_WMV1

Windows Media Audio (WMA) Codecs

  • Major type: MFMediaType_Audio
  • Sub-Type: MFAudioFormat_WMAudioV9, MFAudioFormat_WMAudioV8, MFAudioFormat_WMAudio_Lossless, MFAudioFormat_WMASPDIF

Those encoders are implemented as Media Foundation transform (MFT). Media Foundation offers access to the app through the IMFTransform interface of the encoder. If you are using pipeline layer components for ASF encoding, the encoder MFT is inserted into the pipeline as a transform node since its responsible for transforming media data that flows through the source to the sink. If the  source data is compressed, the pipeline will add the required decoders to convert the source into an uncompressed type.

An encoder has 1 input and 1 output stream. It receives input data. Then, it produces encoded data according to the configuration and format set by the app before the encoding session. The output stream format is described by a media type.

# New Session

When you open Windows Media Encoder for the first time, in addition to the main interface of Windows Media Encoder, the New Session window will also pop up guiding you to make your first activity.

There are two tabs in the New Session window.

1. Wizards

In the Wizards tab, you can do the following operations.

  • Custom session: create a custom encoding session.
  • Broadcast a live event (default): broadcast a live event from attached devices or computer screens.
  • Capture audio or video: capture audio or video content from attached devices and save it to a Windows Media file.
  • Convert a file: convert an audio or video file into a Windows Media file.
  • Capture screen: capture screen images from this computer and save them to a Windows Media file.

2. Quick Starts

  • Capture live content for local playback: use this template to capture audio and video content from devices and encode it to a file for local playback.
  • Capture live content for streaming (MBR): use this template to capture audio and video content from devices and encode it to a file for on-demand streaming from a Windows Media Server using Multiple Bit Rates.
  • Convert film content to video: use this template to convert file-based content that was originally produced on film to Windows Media Format. This template uses bit-rate-based variable bit rate encoding to produce content that is suitable for playback on CD or DVD. It also applies the inverse telecine filter to restore your content to its original 24 fps format.
  • Broadcast company meeting: use this template to broadcast a live event, such as a company meeting, via a Windows Media Server and create an archive of the broadcast for later viewing.

Windows Media Encoder Quick Starts


  • If you don’t want to see the New Session window whenever you launch Windows Media Encoder in the future, just uncheck the “Show this dialog box at startup” option at the bottom left of the New Session window.
  • In the main user interface (UI) of Windows Media Encoder, you can trigger the New Session window from the upper left toolbar.

How to Encode with Quick Starts / New Session Wizard?

Before encoding any content, you have to configure an encoding session. You can make easy access by the New Session Wizard or quick starts.

Quick starts are session files that are included with Windows Media Encoder. They are designed to deal with common encoding scenarios. Quick starts contain most of the settings you need to begin encoding without delay. With quick starts, all you need to do is to provide your source content specifics like file names or server names.

Besides, you can take advantage of New Session Wizard to encode your source files. New Session Wizard will guide you through the steps needed to set up 4 of the most common encoding scenarios.

After you customize your encoding session, you are ready to encode the content. If you want to run the same session in the future, you can save the settings to a session file of .wme extension.

1. In the Wizard tab in the New Session window, click on the Convert a file option and click OK.

2. Specify the source file and provide a name and location for the Windows Media file that will be created through this session.
