Part 1: Reasons behind unplayable MKV file

Not paying attention to the file format is very common unless you encounter an error when trying to play it. The first thing that appears on the mind of every user is the possibility of a damaged video file. However, there are other specific scenarios that make an MKV file unplayable. Let’s discuss them briefly.

Unsupported Media Players:

87.8% of computer users worldwide use PCs with Windows operating system. The default media player of Windows operating system is Windows Media Player which does not support MKV files. It is valid for versions older than Windows 10, and if you want to play a file in MKV format on this player, you need to download particular codecs to make it compatible. VLC is the most widely used video player that fully supports MKV files. So always play your files in a supported player before you conclude that it’s corrupted.

Drivers out of date:

Are you someone who does not update their operating system and keeps slowing them down? Then most likely your video drivers are outdated and causing a problem during playback. If you are using an old device and its drivers are not updated, this could be one of the reasons why your MKV files are not playing. Update the drivers from a trusted source and try replaying to see if the problem is fixed.

Device issues:

Playback problems with video files are sometimes not because there is something wrong with the file. If the general functionality of your PC is affected, perhaps due to a virus or malware attack or if the operating system is not installed correctly, the video players will also not work properly. The best way to confirm that the problem is with your device is to try playing it on another sound device to rule out this cause.

The MKV file is damaged:

Once you have ruled out all the above reasons, it will finally be concluded that the unplayable MKV file is corrupted. This data corruption can be due to various reasons. The most common is that the video data gets infected with a powerful malware or virus, making it unplayable. If you recorded the video yourself from a digital device and a sudden shutdown occurred, or the device was running on low battery while recording or saving, it may also damage MKV files. The use of the MKV format is prevalent in subtitled videos, commonly movies. People tend to get them from unreliable sources, so there is always a risk of them getting damaged – the sudden ejection of storage devices during transfer. MKV files are another factor that leads to the damage of such data.

  • Do not shut down your computer instantly and make sure to avoid all scenarios that lead to it. When you are playing videos, transferring them to/from another device or downloading them, an instant shutdown interrupts the process and causes changes that lead to file corruption.
  • When you want to transfer files to an external device, always scan them for potential malware and viruses. If the storage device is infected with any of them, it will damage your videos. To protect yourself, don’t use your USB flash drives and passport hard drives on public computers or without antivirus.
  • Videos are larger than any other type of data and may take some time to transfer. When the transfer is incomplete, please do not eject your device suddenly. Allow the process to finish and eject properly to prevent data corruption.
  • Take all the essential precautionary measures while recording videos. Don’t overplay them and turn off the camera when not in use. Transfer logged data to a healthy device and back it up to a secure cloud-based storage platform.
  • The Internet is an excellent source of content and you can download tons of informative and entertaining video format data. Just make sure you download them from trusted sources and websites, as they may contain viruses that will damage your existing videos.
