Convert M4V to 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.
About MP4
MP4 is the most widely used video file format in the world. It's a multimedia container that can store video, audio, subtitles, and images. Its success is due to its excellent balance of high-quality compression, which results in relatively small file sizes, and its universal compatibility across virtually all devices, browsers, and platforms. It most commonly uses the H.264 video codec and the AAC audio codec.

Frequently Asked Questions
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.
Is MP4 the same as MPEG-4?
Not exactly. MPEG-4 is a compression standard, while MP4 is a container format. An MP4 file often contains video compressed with the MPEG-4 standard (specifically, codecs like H.264), but the MP4 container can also hold video encoded with other standards, like H.265.
Is MP4 better than MOV?
For general use, especially for web streaming and sharing, MP4 is better due to its universal support and smaller file sizes. MOV is a professional, high-quality format that is excellent for video editing, especially within the Apple ecosystem, but it is less compatible and results in larger files.
