How the MP4 Corruption Tool Works

MP4 files contain video/audio data organized inside "atoms" such as moov, mdat, ftyp, and free. This tool targets portions inside these segments to disrupt video structure without entirely removing the container identity. As a result, most players will throw errors such as:

  • "Cannot play this video"
  • "Unsupported format"
  • "Missing metadata / corrupted header"
  • Playback freezes or refuses to load

Final Notes
