Part 3. WMV vs AVI

While both WMV and AVI were created by Microsoft and are supported by hardware players, they are not entirely the same. One of the greatest advantages that AVI has over WMV (only works on Windows) is that it is compatible across different platforms. AVI also holds higher quality video content, but WMV compresses the contents better and therefore occupy lesser hard drive space. Because of this, if you are looking to stream your videos on social media or transfer them via removable media storage, WMV is your better bet. However, WMV is not an acceptable format to use for video editing. Here is a summary for your easy reference:

Developer Microsoft Microsoft
Cross Platform Functionality Compatible across different platforms i.e. Windows, Mac and Linux Compatible on Windows only
Compression Large file size Small file size
Video Quality High quality video Lower quality video
Uses Video editing and high quality playback on PC Online streaming and removable media storage
Supported by Hardware Players Yes Yes
