How to convert m4v to mp4 on windows 11

You should not wast time on Windows Media Player (WMP) for converting m4v to mp4 on Windows 11.

Limited Format Support​: WMP struggles with many modern video and audio formats like MKV, AVI (with certain codecs), FLAC, and even M4V. You often need to install ​​separate codecs​​ or use a different player just to play your files.

​​No Format Conversion​​: As you've discovered, WMP can't convert files from one format to another (e.g., M4V to MP4). This basic functionality is expected in most media apps today.

​​Poor User Interface​​: The interface feels clunky and outdated compared to sleek, modern media players. Navigation is not intuitive, and features are buried in menus.

However, you can use this free m4v to mp4 converter instead:​​

1. Download and install VL1C Media Player if you don’t already have it.

2. Open VL1C. Go to ​​Media​​ > ​​Convert / Save...​​

3. Click ​​Add​​, then select your M4V file and click ​​Open​​.

4. Click ​​Convert / Save​​. In the ​​Profile​​ dropdown, select ​​Video - H.264 + MP3 (MP4)​​.

5. Click the ​​Browse​​ button next to "Destination file" to choose where to save the MP4 and give it a name.

6. Click ​​Start​​ to begin the conversion.
