However, like any other multimedia files, MP4 videos are also susceptible to corruption and in such cases your videos will become inaccessible. Such errors usually arise due to incomplete downloads, file transfer errors, software issues, system crashes, etc. Whatever is the cause for the corruption of MP4 video files on your device, don’t lose hope. The good news is that you can always repair those videos by applying proper video repair methods. Here, in this quick guide, we will explain different approaches to repair MP4 videos and restore your precious memories.

Identifying the Exact Cause for MP4 Video Corruption

Before you apply any method to fix corrupted video files, it is important to understand the exact cause of this issue. Here are some common reasons why videos get corrupted on Windows/Mac devices:
  • Incomplete Downloads: If your MP4 video file is not completely downloaded or encounters network issues while downloading, it leads to corruption issues. Incomplete downloads usually leave the file with missing or damaged data, which makes it unplayable.
  • Codec Issues: Incorrectly installed or outdated codecs can cause video playback errors and corrupt video files. You can install compatible codecs or use a reliable video converter to resolve the codec incompatibility of MP4 files.
  • Improper File Conversion: When your MP4 video is not properly converted to another file format, it may introduce corruption issues. Usually, such instances occur due to incorrect settings, software errors, or using unreliable conversion tools.
  • Power Failures or System Crashes: Sudden power outages or system crashes while recording or saving an MP4 file can cause corruption. The sudden interruption disrupts the writing process, making the video file incomplete and potentially corrupted.
  • Header Corruption: The header of your video file contains important information like frame rate, resolution, and codec details. If the header anyhow gets damaged or corrupted, it results in playback issues and makes your video unplayable.
