Why Do MTS Video Files Get Corrupted? How to Fix Them?

Have you recorded a video on your camera but now can’t access it? Your MTS videos could be corrupted. Fortunately, you can repair MTS video files with our detailed guide.

We’ll explain what MTS video files are, cover the most common causes and signs of their corruption, and the five proven ways to repair corrupted video files. Let’s get to it.

What Are MTS Video Files?

MTS stands for MPEG Transport Stream and is a file extension primarily characteristic of AVCHD (Advanced Video Coding High Definition) video files. Besides an AVCHD, an MTS file can also be a MadTracker sample or MEGA tree session file.

Panasonic and Sony cameras primarily record MTS files, which are high-definition videos. Moreover, they are easy to share or convert on a computer. AVCHD videos support 720p and 1080p videos and usually have the MTS format on devices.

Like any other video file format, MTS videos can get corrupted. Being unable to open and play your MTS videos due to file corruption can be frustrating. So, why does that happen?

These are the most common reasons for MTS video corruption:

  • Virus infection – If your MTS video file suffers a virus attack, it’ll get corrupted and become unplayable.
  • Interruption during download – Anything that suddenly interrupts your download process could damage your MTS video.
  • Hard drive corruption – If you store MTS videos on a corrupted disk, it will suffer the same fate.
  • Video compression issues – Compressing your MTS videos makes them prone to corruption.
  • Sudden power failure – Your MTS video file can get corrupted if you encounter sudden power loss while viewing it.

How to Recognize Corrupted MTS Videos

MTS video file corruption is easy to recognize. The inability to play the video or constant freezes are the tell-tale signs. Another way to be sure your MTS video file is corrupted is to check for error messages.

If you keep seeing the following error messages when attempting to play an MTS video file, you’re experiencing video corruption:

  • “Cannot open the MTS video file.”
  • “Problem with .mts file: incorrect length.”
  • “An error occurred loading the .mts file.”
  • “Disk is not formatted.”
