In this article, we’ve listed down ways to identify if a video file is corrupt and how you can repair it on your own Mac!
What causes video files to get corrupted?
How can you tell if your file has indeed been corrupted? Well, it could show any of the following symptoms:

- Damaged or broken video header
- Faulty storage device
Ways to Repair Corrupt Video Files on Mac

VLC Media Player
The VLC Media Player is a popular video and audio player, with multiple features that make it very convenient. But did you know that it is also a reliable way to repair corrupt MOV, M4V, or MP4 video files on Mac? It can fix the files in two methods:
Method 1. By converting the format or the codec of the video file.
- First, download VLC Media Player on your Mac and launch the software once it’s installed.
- Look for Media from the menu bar on top of the app interface. From there, select Convert / Save.
- A dialogue prompt will pop up. From there, select the video in question and click on Convert / Save.
- Next, provide a new name for the repaired video file. In the section below, choose the Encapsulation or file format of your choice and press Save.
After the software has taken all settings and changes into account, it will run a quick repair to fix any problem raised by an incomplete code or wrong format.
Method 2: Changing the file extension of the video.
This next method transcodes the file to another file through its settings. This way, any errors caused due to compression or editing are identified and fixed. Here’s how to do it:
- First, launch the VLC Media Player and then make a copy of the corrupt video file on your Mac.
- Next, change the file extension of the copy to “.avi” and save it in your preferred location. VLC will automatically identify errors in this format. Wait a few minutes for the file to completely convert.
- Then, click on the Tools bar from the menu section. Go down until you see Preferences.
- From the Preferences menu, choose the necessary input and codec and save it.
- Finally, select Always Fix.
The VLC media player will scan the corrupt file in the “.avi” format after you click on Always Fix and start the necessary repair by itself. Give the process a minute and then it will be ready with a brand new, fully functional video.
