| Name | WMV | M4V |
| Full name | Windows Media Video | Raw MPEG-4 |

| MIME | video/x-ms-wmv | video/x-m4v |
| Developed by | Microsoft | Apple Inc. |
| Type of format | Video file format | Video container |
| Introduction | Windows Media Video (WMV) is a file type which can contain video in one of several video compression formats developed by Microsoft. The original video compression format used in the file, also known as WMV, was originally designed for Internet streaming applications, as a competitor to RealVideo. | The M4V file format is a video container format developed by Apple and is very similar to the MP4 format. The primary difference is that M4V files may optionally be protected by DRM copy protection. Apple uses M4V to encode video files in its iTunes Store. |
| Technical details | A WMV file uses the Advanced Systems Format (ASF) container format to encapsulate the encoded multimedia content. While the ASF can encapsulate multimedia in other encodings than those the WMV file standard specifies, those ASF files should use the .ASF file extension and not the .WMV file extension. | Unauthorized reproduction of M4V files may be prevented using Apple's FairPlay copy protection. A FairPlay-protected M4V file can only be played on a computer authorized (using iTunes) with the account that was used to purchase the video. |
