Part 2. The Causes of MKV Video Corruption

As mentioned earlier, though MKV is a dependable file format, it is still pretty sensitive to corruption challenges. Some of the major factors contributing to MKV video corruption are listed and elaborated on below.

1. Power Failure

A sudden failure of a power supply can be one of the leading reasons for a corrupted MKV video file. Power failure is not only dangerous for your video files, but it is equally harmful to your computers.

2. Abrupt Switch Off

Sometimes, while operating our system, we abruptly turn it off and get busy with other tasks, leading to a corrupt video file. If you are also involved in this activity, try avoiding it on priority and switching off your device once all applications are properly closed.

3. Media Player

If your media player is not compatible with the MKV files you are trying to play with, it can result in corrupted MKV videos. Therefore, before you play your videos, don’t forget to ensure whether or not your media player supports MKV files.

4. Improper Downloading

If you download your files from unverified online sources, they may get damaged. Always spend some time finding trusted sources to download your files from. Similarly, improper downloads have also caused video corruption many times. In addition, faulty or poor internet connection can also result in a corrupted MKV video.

5. File Conversion

Sometimes, we convert our files into different formats we feel comfortable with. But, you should be aware that conversion to an incompatible format can damage your MKV files.

6. Virus Attack

Malware can attack different files on your computer. It can also badly affect your MKV files. To deal effectively with this challenge, you must have powerful antivirus software installed on your computer to update regularly.
