“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?”
Numerous queries, such as the one mentioned, have been posted on Apple Inc. and various media player forums, yet a definitive solution for repairing and accessing M4V files remains elusive. This article will delve into the intricacies of how to repair M4V video files. However, before we embark on that journey, let’s gain a better understanding of this file format.
What is the M4V file format?
Apple Inc. introduced the M4V video file format specifically designed for encoding video files available on the iTunes store. M4V video files share similarities with the MP4 format; however, they come with Digital Rights Management (DRM) protection. This DRM protection restricts their playback to platforms that support iTunes and QuickTime. Surprisingly, even with this protective mechanism, issues may arise, and you might encounter situations where you need to learn how to repair M4V video files since they can become corrupted, rendering them unplayable on any compatible platform.
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
Practically any file format has the potential to become corrupted as a result of viruses, malware, spyware, or Trojan attacks targeting storage media or the system itself. Such incidents can result in significant harm to your M4V files.
File conversion
In an attempt to convert the M4V file to any other platform which is not supported by Apple, a proper technique and suitable software must be used. If not, the result can be a corrupted video.
Header corruption
Sometimes while converting an M4V file to any other format, the header of the file gets corrupt, making it unplayable.
Immediate termination
Situations like an immediate shutdown of the system, power outages, or closing the media player accidentally often lead to forceful termination of video, which can cause M4V file corruption.
Corrupted storage media
There can be times where the carrier of the video file can be corrupted and can spread the same to the M4V videos.
Repairing highly corrupt M4V files is not possible, but you can use the methods mentioned below to fix M4V files with a minor level of corruption-
Change the codecs
Each video file contains encoding that facilitates efficient transmission and is utilized only when necessary. However, if the codec is either absent within the file or malfunctions, it renders the file unplayable. Consequently, it is advisable to verify the presence of any missing codecs or attempt to substitute them in order to regain access to the corrupted M4V video file.
Download video from a reliable source
Many users frequently acquire video files from untrustworthy and unreliable platforms, leading to file corruption. Even readily available sources may not guarantee security. Therefore, it is advisable to obtain the M4V video file from a trusted source to prevent any potential corruption.
Update video drivers
If your system’s video drivers are outdated, they can potentially cause issues with the functionality of M4V videos. Therefore, it’s advisable to verify the currency of your laptop’s media drivers and, if necessary, obtain the most recent updates to ensure smooth operation.
Convert video format
If M4V files become corrupted, you may want to contemplate converting the M4V video file to an alternative format, such as MP4, AVI, MOV, or any other format that offers greater accessibility and compatibility. To facilitate this conversion, you can utilize Kernel Video Converter software, ensuring that your M4V video can be played without any hassle.
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 software.
