I had a .m4v video file in my system, but the media player in my computer was unable to play it, and even if it starts playing, there was no audio or video output. Why my .m4v file is not playable with any media player?

Many inquires like the above were submitted on Apple Inc. and other media players forums, but no ideal solution is provided to repair and access m4v files. In this article, we will talk about how to repair m4v video files, but before that, let’s know a bit about this file format.

What is the M4V file format?

Apple Inc. developed M4V video file formats for encoding video files on the iTunes store. It is no different than the MP4 format, but they are encoded with DRM protection (Digital Rights Management), which makes their usage limited to iTunes and QuickTime supporting video files.
Well, it doesn’t matter whether the m4v file is DRM protected or not if it gets corrupt, it will not be playable on any of the platforms.

Reasons for the M4V File Corruption

There could be multiple reasons behind an m4v file corruption. However, the most common reasons include:

  • Virus or malware attack
    Almost every file format get corrupts due to virus/malware/spyware/trojan attacks on storage media, and this can be the case with your m4v file.
  • Due to file conversion
    If you try to convert the m4v file to any other format without using a proper technique to play it with non-Apple devices, then also the file gets corrupt.
  • Header corruption
    Sometimes after converting an m4v file to any other format, and try to play it, the header of the file gets corrupt, making it unplayable.
  • Immediate termination
    Situations like the immediate shutdown of the system while playing the video, power outages, or closing the media player accidentally often lead to forceful termination of video, which can cause m4v file corruption.

Methods to Repair Corrupt M4V Files

Repairing highly corrupt m4v files is not possible, though you can use the below-mentioned methods to access m4v files with minor corruption issues.

  1. Change the codecs
    Every video file is encoded with codes that help in faster transmission and is activated only when the file requests for it. But, if the codec is not available with the file, or doesn’t function properly, then the file will not be playable. Therefore, check for missing codecs or try to change them to access the corrupt m4v video file.
  2. Download file via a reliable source
    Many users around the world often download video files from uTorrent, which results in corruption in the file. So, prefer downloading the m4v video file from a reliable source to avoid any corruption in it.
  3. Update video drivers
    When the video drivers on your system are not updated, it might stop the m4v video from functioning. So, check whether media drivers on your laptop are up-to-date or not and if not, then download the latest drivers.
  4. Convert video format
    If m4v files are corrupt, consider changing the format of m4v video file to any other similar format like MP4, AVI, MOV, or any other. If the conversion is successful, you’ll be able to play your m4v video file.

These are just some common solutions that can be helpful in repairing corrupt m4v video files. However, if none of these solutions work for you, then you should opt for video repair softwareKernel Video Repair.
