Microsoft has also developed a digital container format called ASF (Advanced Systems Format) to save WMV video encoding. Under the same video quality, WMV format files can be played while being downloaded, so they are very suitable for online playback and transmission.

Container format

WMV files use the ASF (Advanced Systems Format) container format to encapsulate encoded multimedia content. Because ASF can also encapsulate multimedia content using other encodings that are not specified by the WMV file standard, ASF files use .ASF as the file extension instead of .WMV as the file extension.

Although WMV is usually packaged into the ASF container format, it can also be packaged into the Matroska or AVI container format. The extensions of such files are .MKV or .AVI respectively. A common way to save WMV to AVI files is to use the WMV 9 Video Compression Manager codec implementation.
