Part 1: Reasons behind M4V File Getting Corrupted

Are you wondering about the reasons behind M4V file corruption? Here are a few reasons why your M4V file may get corrupt:

  • Virus and Malware: Virus and malware attacks are one of the most common reasons for file corruption. If a virus attacks your M4V file, it is highly likely to corrupt.
  • Bad Sectors: Bad sectors on hard drives or other file system issues often lead to corruption. If the system faces an issue while reading or writing data, it can cause your M4V file to go corrupt.
  • Background Interruptions: If an application running in the background interrupts the file being played, it can break video codecs and render the file inoperable.
  • Abrupt Shutdowns or Transfers: Incomplete transfers, uploads, or downloads of an M4V file can cause it to go corrupt. If your system experiences sudden power outages or irregular shutdowns, it can also impact the file.
  • Incompatible Media Players: If you try playing your M4V file on media players that do not support the file format, it can damage the file. This can damage the file headers and make the stored data inaccessible.
