Convert M4V to HEVC
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 HEVC
This refers to a raw video stream encoded with the HEVC (High-Efficiency Video Coding) codec, also known as H.265. HEVC is the successor to H.264 and offers about 50% better compression efficiency, meaning it can deliver the same quality at half the file size. This makes it ideal for 4K and 8K streaming. A raw .hevc file must be placed in a container like MP4 or MKV to be useful.

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 HEVC/H.265 the future of video?
It is the current standard for high-resolution video delivery (like 4K Blu-ray and streaming). However, its adoption has been hampered by complex and expensive patent licensing. Newer royalty-free codecs like AV1 are competing to become the next universal standard.
Why do I get an error playing an HEVC file?
Playing HEVC video requires either hardware or software support for the codec. Older devices may not have the necessary hardware decoders. You may need to update your media player, install a codec pack, or use a modern player like VLC that has built-in support for HEVC.
