How to Repair Your Corrupted MP4 or MOV Files

Video files play an essential role in the modern world as your life, in a way, revolves around them. Your important data is stored in video form if you are a professional videographer or a content creator. In personal life, many memories are stored in this form, from birthdays to weddings and more. MP4 and MOV are the most widely used video formats for creating and storing videos. So, if your important MP4 or MOV files get corrupted, it can hurt you greatly. 

Luckily, now files getting corrupted doesn’t mean that these are gone. With the Wondershare Repairit video repair tool, you can easily repair even severely damaged MP4 and MOV files. We will explain the difference between MP4 and MOV, the reasons behind data corruption, and how to repair MP4 and MOV files.

Part 1: Major Differences Between MP4 and MOV Video Formats

MOV, developed by Apple, and MP4, developed by ISO, are among the most used video format in the digital world. MOV is the default and goto format for all Apple devices, while MP4 is supported by all operating systems, video players, and editors. MP4 and MOV work on the lossy compression algorithm, but MOV still retains high quality and boosts larger video. 

MP4 vs MOV

Regarding size scalability, MP4 is ideal as it could be scaled to the desired size while maintaining quality, though not as high as MOV offers. Due to its ability to retain high quality and being easy to encode, MOV is widely popular when it comes to professional video creators. MP4 is mostly popular with content creators due to its availability on a wide range of devices and flexibility regarding file size.

Part 2: Primary Causes Behind MP4 or MOV Files Corruption

There are many reasons behind the corruption of your MP4 and MOV files. It can range from malicious virus attacks to failed file transfers or because of a sudden system shutdown. The files can also be corrupted if you try to run them with incompatible software. Below are a few of the main reasons mentioned in detail:

1. Virus or Malware Attack 

A virus or malware attack can affect and corrupt data on your system, making it useless to you. Video files are usually very susceptible to virus attacks making them a prime target. You should always create a backup of your essential data or use good anti-virus software.

2. Improper System or Software Shutdown

MP4 or MOV files can also get corrupted if you run them and a sudden system shutdown occurs. It can easily make the file being played corrupted. Similarly, if the software you use to play or edit MP4 or MOV files gets closed suddenly, it can corrupt the file.

3. Disruption in File Transfer or Download

Video files can also get corrupted if you export them from an external device like a USB or external storage device, and the process gets disrupted in between. It can also happen if you copy files from one place to another. Similarly, in the case of downloading the file, slow internet speed or loss of connection can result in file corruption.

4. Improper Conversion and Compression

Your MP4 or MOV files can also become corrupted during conversion to another format if the process is disturbed. It can also be the case that the converter you were using was lackluster. In the same way, if you are not able to properly compress the files, your MP4 and MOV files can get corrupted.

5. Inappropriate Read and Write and Broken Headers

All the media files have an internal structure and set of written code that is constantly being modified when we run those files. So, files can get corrupted if you are running your MP4 or MOV files with an incompatible or corrupted media player. Missing or broken headers of MP4 and MOV files can corrupt them.
