Part 1: What Causes Leads to Corruption of MP4 Files?

To solve any problem, it is important to understand the reasons which cause it. Therefore, here are some of the causes that lead to the corruption of MP4 video files:

1. Physical Damage

If your video files are stored in some storage device like CDs or hard disks, they are likely to get corrupted by physical damage. Coming in contact with hard surfaces, handling them with a rough hand, or inserting them wrongly can damage the storage devices. Obviously, if these devices get damaged, the data present in them will also get damaged.

2. Error Reading and Writing of Data

Any file, whether it is audio or video, comprises an internal architecture along with some specific codes. While editing, their codes may redefine, and this internal architecture may vary. Moreover, if the problem is in your device, it will lead to the error of reading and writing data present in your device. No proper check and balance of the device can lead to this problem.

3. Power Outage

Improper shutdowns regularly affect the system and the data in a bad way. If you are working on a file and there is a sudden power outage, the chances of that file getting corrupt are high. Especially if your system shutdowns while an MP4 file is playing in the background, it can damage the file.

4. Virus or Malware Attacks

The video files can get corrupted if the virus enters the device and target specific or general files. Any virus can tamper with the file’s structure, whether audio or video, and lead to these being damaged. Opening inappropriate sites or downloading from defective links can be a gateway for a virus or malware to enter your device.
