Part 1. What Caused MP4 Videos to be Damaged

Even with today’s advanced devices and software, MP4 videos remain vulnerable to damage. A single glitch during recording, transfer, or playback can corrupt the file, making it partially playable or worse, completely unplayable. The damage may range from minor visual distortions to total loss of audio and video. With this, understanding what causes MP4 files to fail is essential, as it helps you prevent issues before they happen and choose the right MP4 fixer tool to use. Below are some of the most common causes:

Interrupted File Transfer

If your computer, camera, or phone loses power, disconnects, or shuts down unexpectedly during a file transfer, the process may stop mid-way. This often leaves the MP4 file incomplete, missing vital data that prevents it from playing correctly.

Faulty Storage Devices

Physical issues with storage media, such as bad sectors in hard drives or corrupted memory cards, can damage the data they hold. Over time, wear and tear or manufacturing defects can cause these devices to corrupt your stored videos.

Improper Compression

Compressing MP4 files with low-quality or untrusted software can remove or damage essential metadata and video frames. This can lead to errors such as missing segments, distorted visuals, or audio-video desynchronization.

Software Crashes

Editing, converting, or exporting a video while using unstable software can result in a sudden shutdown or error mid-process. This can leave the MP4 file partially written or corrupted, making it unplayable afterward.

Virus or Malware Attacks

Harmful software can directly modify, overwrite, or delete portions of your MP4 file. In some cases, viruses may encrypt or scramble the data, making it impossible to open without repair or recovery.

Unsupported Codecs

MP4 files require specific codecs for proper playback. If these codecs are missing, outdated, or incompatible, your media player might mishandle the file, leading to playback errors or even damage during attempted processing.
