MP4 is the most used format to store video files, along with multiple audios and subtitles. It is common to see various problems related to audio distortion, video black-outs to even read errors while playing an MP4 file. If you witness such problems, the MP4 file may likely have a corrupt file header. A header in an MP4 file contains crucial information that is read by both media players and video editing software to run videos.

In this article, we explain the common reasons that cause MP4 header damage, how to identify corruption and repair mp4 headers, and to prevent headers from getting corrupted again.

Part 1. What is MP4 Video Header Corruption

An MP4 header contains information such as the resolution, format, size, settings, etc. of a video. Any phenomena that destroy/change this data can leave the file useless. There are several ways to know that your file header has corrupted. Some of the most common ones are:

  • 1. The video won't play in any media player.
  • 2. Video blacks out or freezes in the middle.
  • 3. Jerky, blurry, or choppy video.
  • 4. The sound gets distorted or sometimes omitted.
  • 5. Out-of-sync sound and video.
  • 6. The MP4 file becomes unreadable.
