What is WMV File Format and How to Open It

Nataliia Paraskeva Feb 4, 2025

WMV is a widely used format that was introduced by Microsoft in 1999. The WMV file type is designed to compress audio and video files, providing twice as much compression as the similar MPEG 4 format. As a result, it’s the ideal format for users looking for a way to easily share compressed media online. The extra compression does lead to a certain loss in quality.

However, given the impressive levels of compression and the added convenience this provides, WMV is still a very widely used format. Given the likelihood that you’ve already got numerous WMV files saved in your library, it’s worth investing in a player such as Elmedia Player that lets you make use of this format. The Elmedia WMV player for Mac can handle WMV, as well as a huge range of other file types.

The Two Kinds of WMV

Because "WMV" has a double meaning, it's recommended that you read the text 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.

User scenario:

Help! I can usually find out how to work problems out on my computer, but I can't understand how to do this. My friend sent me a video of her vacation and I'm trying to open the video. They're in different parts. The format is .wmv.001-12 and I don't know how to view them! — Tech Support Guy
