What Is M4V? Apple Video Format | DRM, Playback & Conversion

M4V is a video format you might encounter while watching or downloading videos from Apple. This format is associated with iTunes, Apple TV, and Apple devices. It has been used for movies, TV shows, podcasts, and other video content. But what is M4V, exactly? Simply put, M4V is similar to MP4, but it has one important distinction: some M4V files are protected by DRM while others are DRM-free. That difference can affect how you play, rename, transfer, or convert an M4V file. In this post, you'll learn the definition of M4V, how it compares with MP4, and when you can rename it. Also, we will show how to play and convert these files.

What Is an M4V File?

What is an M4V file? M4V is Apple’s video format based on MPEG-4 and closely related to MP4. It can hold video encoded with H.264 or H.265 and AAC or AC-3 audio. Apart from video and audio, it can also contain metadata and an optional FairPlay DRM. To let you know, M4Vs have two types: DRM-free and DRM-protected. These types are used for podcasts, movies, and TV shows distributed through iTunes and Apple TV.

M4V with DRM vs M4V Without DRM: What's the Difference?

To better understand the two types of M4Vs, we will explain them in more detail in this section. The .m4v extension alone won't determine if the file is protected.

• M4V with DRM: Movies and TV shows purchased or rented from Apple TV, or iTunes use FairPlay DRM. It is a restriction that limits how protected media is accessed and played.
• M4V Without DRM: An M4V with DRM, or a DRM-free M4V, is a regular video without any encryption. It can be a home video, a personal recording, an exported video, or any M4V that falls into this category.

M4V vs MP4: Can You Just Change the Extension?

Referring to the outlined question, the answer is sometimes, yes. DRM-free M4V format contains media compatible with the MP4 container, and you can rename .m4v to .mp4 without re-encoding the video. However, renaming it does not convert and remove FairPlay DRM. Changing the filename of an M4V with DRM to .mp4 won’t decrypt its content. Likewise, even a DRM-free M4V requires a conversion if the codecs, structures, or other streams are incompatible with your target device.

How to Play M4V Files on Non-Apple Devices

Apple Devices

Apple TV app is Apple's built-in media application for watching movies and TV shows. Below are the two ways to play them:

• DRM-free M4Vs: Double-click the M4V file to open it in QuickTime Player, or transfer the video from the computer to the iPhone.
• DRM-protected M4Vs: Log into the exact Apple Account used to purchase the M4V to authorize the default media player to play it back.

Windows

You can use VLC Media Player to play unprotected M4Vs on your Windows system. This established media player can play nearly all media files and formats, including M4Vs.

To play: Navigate to Media and select Open File to import M4V. You can also drop the file directly into the interface to start the playback.

Android

Android devices cannot play purchased or rented M4Vs because these files use codecs that standard Android media frameworks cannot decode. It means you cannot play the files outside Apple-approved software. In this case, you need to convert M4V to MP4.

Chromecast and Smart TVs

Chromecast and Smart TVs cannot open and play M4Vs natively. However, if the file is unprotected and uses a codec similar to MP4, certain media players can cast it. Still, support is inconsistent on different brands and USB ports.

What Happens When Your Apple ID Authorization Expires?

When the Apple ID authorization expires, Apple’s FairPlay DRM blocks access to your purchased media. Apple uses FairPlay DRM to encrypt iTunes movies and TV shows in M4V format. You can only authorize up to 5 computers simultaneously per Apple ID. When you play a movie, iTunes checks your local authorization key against Apple's servers. If authorization expires, your computer loses the decryption key, causing playback to fail.
