What is .WMV File Extension?

What does WMV stand for? "Windows Media Video" is a Microsoft format, created for the purposes of video encoding, playback, and streaming on PC. It can significantly compress a video while keeping its quality, which is important for the Web, or storing a large amount of files. At first, the format was inaccessible. But later, it was standardized by SMPTE and released to the public. However, it remains a licensed property of Microsoft. The format is widely supported on Windows systems, and mostly incompatible with macOS.

WMV Facts and Trivia

  • WMV video streams are packaged in ASF containers, despite having the .wmv file type.
  • WMV encoded video can also be stored in Matroska files and AVI.
  • WMV can contain DRM - for example, files from the Zune marketplace can't be played on other systems.
  • Besides video, a .wmv file can contain a slideshow or a screencast.
  • WMV file format is based on MPEG-4, one of its primary competitors.
  • Microsoft uses DRM-enabled WMV as a standard for video distribution, especially time-limited subscription-based services.

What is the WMV format good for?

  • High compression ratio, for faster streaming and easier storage. Reportedly, twice as high as MPEG-4.
  • Specifically, it's a good choice for an email attachment. It also used to be supported by Silverlight, but the plugin was discontinued.
  • If your video has a WMV file extension, it certainly runs on any Windows-powered device.
  • High backward compatibility, especially for MS software.
  • It's a proprietary, commercially developed format, likely to be of high quality.
  • Online playback supported by Google Drive.
  • Can be processed in most video converters.

What are its downsides?

  • Low compatibility with non-Microsoft systems. However, on Apple products, there are some popular solutions, such as QuickTime with Flip4Mac, and ShredWorx Smart Converter.
  • Brutal DRM. Microsoft peppers its media with multiple types of copy protection, locking videos down to specific times, places, and devices.
  • When decoding the video, many players can lag and stutter. It’s quite CPU-intensive.
  • "WMV" can refer either to the video codec, or a file format, which can have a different encoding. This leads to confusion, and a video player or a converter might fail to recognize a .wmv file.

The Two Kinds of WMV

Because "WMV" has a double meaning, it's recommended that you read the illustration below to discern between an MKV video file and an .mkv container.

As a Video Encoder

A codec is a program used to compress or extract video and audio data. Depending on its role, it can be either an encoder or a decoder. A good codec will save space, and a better one will minimize quality losses. Usually, it's a trade-off between quality and compression levels, but over time, there is always some improvement. There are separate codecs for video and audio, so to combine them, the two media types are stored together in a container.

As a Container File

Container files are used for their convenience. One of their obvious benefits is that you don't have to open video and audio tracks separately. They are also useful because of other features, such as subtitles, and storing multiple different audio tracks (for example, in different languages). The container itself also holds information on its contents, such as their codecs. The .wmv container format is a subtype of .asf, and it usually contains WMV-encoded video and WMA audio. File extensions are mainly used by humans; a format, if it's needed, is usually coded into the file. A .wmv and an .asf are virtually the same, as long as they contain the same set of video and audio files. Of course, there are also different formats of containers.
