WMV is a digital video compression format developed by Microsoft, which is part of the Microsoft Windows media framework; WMV files are more suitable for playing and transmitting on the Internet, and allow audio to be played synchronously with video.

WMV (Windows Media Video) is a general term for a series of video codec and related video coding formats developed by Microsoft, which is part of the Microsoft Windows media framework.

WMV is a streaming media format and a digital video compression format developed by Microsoft. This kind of file is more suitable for online playback and transmission, and allows audio to be played synchronously with video.

WMV includes three different codecs: as a competitor to RealVideo, WMV's raw video compression technology was originally designed and developed for streaming applications on Internet; the other is WMV screen and WMV image compression technology to meet specific content needs. After being standardized by SMPTE (Society of Motion Picture and Television Engineers), WMV version 9 was adopted as a distribution format for physical media, such as HD DVD and Blu-ray discs, known as VC-1.

Microsoft has also developed a digital container format called ASF (Advanced Systems Format), which is used to store WMV video coding. Under the same video quality, files in WMV format can be downloaded and played at the same time, so it is very suitable for playing and transmitting on the Internet.

Container format

WMV files use ASF (Advanced Systems Format) container format to encapsulate encoded multimedia content. Because ASF can also encapsulate multimedia content with encodings specified by other non-WMV file standards, ASF files use .ASF as the file extension instead of .WMV.

Although WMV is usually packaged in ASF container format, it can also be packaged in Matroska or AVI container format, which has the extension .MKV or .AVI, respectively. A common way to save WMV to an AVI file is to use the WMV 9 video compression manager codec implementation.
