WMV files.
WMV (Windows Media Video) files are saved in the Microsoft Advanced Systems Format (ASF). They are then compressed with Windows Media Video (WMV) compression. WMV files store high-quality animation, TV episodes, films, and video clips in Windows. By compressing these files into smaller files without losing any quality, you can save space and/or send a video quickly.
Discover the history of WMV files, how they’re used, their strengths, weaknesses, and more.
What is a WMV file?
WMV files, identified with a .wmv file extension, are the short name for Windows Media Video files. They're compressed with one or more video formats by Microsoft, and are saved in the Microsoft Advanced Systems Format. WMV files consist of three video codecs — WMV screen, WMV image, and the original video compression system, WMV, which is used to compress ASF videos.
WMVs support high definition (HD) video and also support encryption for use with Digital Rights Management (DRM) systems. This makes WMV a popular method for streaming films online in high quality. It also means WMV features on Blu-ray discs. Animators also use WMV to make short animations via third-party programs.
You shouldn’t confuse WMVs with WMAs. This stands for Windows Media Audio, and those files only consist of audio data, not video. However, WMA is typically the audio format used in WMV files.
History of the WMV file.
Microsoft introduced WMV files to its Windows Media framework in 1999. The WMV format was very popular in the 2000s, thanks in part to the huge reach of Windows.
In addition to becoming the default video file format for Windows Media Player, WMV files were commonly used by various media players, often bundled with Windows. Streaming services such as YouTube also allow users to upload WMV files by way of converting through third-party programs.
However, the waning popularity of Windows Media Player over the years has affected the usage of WMV files. Developers looked to create cross-platform video file formats that could rival the compression ratio of WMV.
One file type in particular, MPEG-4 Video (MP4) has become much more popular, thanks in part to the fact they run on Apple devices.
How to use WMV files.
You can use WMV files in a number of ways to play back high-quality video, audio, and text.
Streaming.
As WMV files maintain good quality after compression, they’re great for high-quality streaming. Popular streaming services such as YouTube allow WMV file uploads.
Sharing.
WMV is one of the only file formats small enough to enable you to send video via email. But it’s best to only do so if it’s a small file. You may have to send it as a ZIP file or through another compression method.
Physical formats.
WMV version 9 is adopted for physical formats, including Blu-ray, after standardization by the Society of Motion Picture and Television Engineers (SMPTE). Physical formats are decreasing in popularity as streaming grows but Blu-ray is still popular with lovers of HD-quality movies.
Pros and cons of WMV files.
As with all file formats, there are pros and cons when it comes to using WMV files. Let’s weigh up the advantages and disadvantages of WMV.
Pros.
- Small size. WMV files can hold a large quantity of video and audio in small storage spaces. So, they’re useful if you want to stream or share online.
- Windows compatibility. WMV is the default video format for many Windows devices and is compatible with all Windows hardware and software.
- Lossless format. The video quality of WMV remains the same after compression. Its main rival, MP4, is lossy, so video quality suffers when it’s compressed.
- Convertible. Lots of third-party WMV converters are available, enabling you to convert WMV into files that are compatible with devices other than Windows.
Cons.
- Proprietary to Microsoft. One of the biggest disadvantages of WMV is the incompatibility with other operating systems. But there are ways around this, including WMV file converters and third-party media players.
- Digital rights management system (DRM). Critics of WMV often cite the DRM attached to WMV files, which can make it impossible to restore licensing information.
- Application usage. Some applications aren’t designed to work with the small size of WMV files.
