Convert WMV to M4V
About WMV
WMV (Windows Media Video) is a video compression format developed by Microsoft. It was designed for streaming purposes and was a key part of the Windows Media framework. While it offers good compression and was popular in the early days of internet video, its proprietary nature has led to it being largely replaced by more universally supported formats like MP4.
About M4V
The M4V file format is a video container format developed by Apple and is very similar to the MP4 format. In fact, they are often interchangeable. The primary difference is that M4V files may optionally be protected by Apple's FairPlay DRM copy protection, which is used for videos purchased or rented from the iTunes Store.

Frequently Asked Questions
Can I play WMV files on a Mac?
Playing WMV files on macOS is not natively supported. You will need to download a third-party media player like VLC, or install a component like Flip4Mac (though this is also becoming legacy) to enable playback in QuickTime.
Is WMV still used today?
WMV is largely considered a legacy format. Its use is now mostly confined to older Windows-based systems or specific enterprise environments that have not updated their infrastructure. It is not recommended for creating new video content.
What's the difference between M4V and MP4?
Functionally, they are nearly identical. An M4V file without DRM can be renamed to .mp4 and will play without issues. The .m4v extension is primarily used by Apple to identify videos for its ecosystem (iTunes, Apple TV), especially those that contain DRM or AC3 audio.
Can I play M4V files on non-Apple devices?
If the M4V file is not protected by DRM, it will play on most devices and players that support MP4. If the file is protected with FairPlay DRM, it can only be played on authorized devices, such as those signed into the Apple ID that purchased the video.
