  • Any sort of virus or malware attack on the AVI video file can damage the header and make the video unplayable. 
  • Most AVI header files also get corrupt, if you are continuing to record videos even when the camcorder is showing a low battery warning sign. 
  • There are chances of an AVI file header getting corrupt if AVI files are stored on an infected SD card. 
  • Any sort of corruption in the file system of the Windows / Mac operating system on which AVI files are saved is also responsible for AVI header file damage.

How do I Fix a Corrupted AVI file Header?

Here are top two recommended ways using which you can fix the corrupt AVI file header easily by yourself. One solution is fixing the damaged AVI header using VLC manually and the second method is using an reliable tool to do the task for you effortlessly. 

The header of an AVI file contains the metadata of the video such as the bit rate of the AVI file, number of video frames, size of a frame in pixels. So, a media player takes a header into reference when you play any AVI video. Hence, when the header file is broken or damaged you will receive a notification from the media player saying “Windows media player encountered an error while playing this video”, the file could not be played, etc.

Method 1: Fix Damaged AVI Header using VLC

The first recommendation to any user would be to fix the AVI video file using the VLC media player. Matter of fact, when you open an AVI file with a corrupted header in the VLC media player, the player will deliberately ask you to fix the video through a pop-up box with a “build index then play” option. 

You can enable an automatic repair program in VLC if you have more than one corrupt AVI video file. Follow the below-mentioned steps to enable the always fix option. 

  • Open VLC Media Player.
  • Click on Tools from the menu bar and then click on Preferences
  • Select the Input/Codecs option

Select Input/Codecs Option

  • In the Damaged or incomplete AVI file section, select Always fix and then click on the Save button.

Select Always Fix Option

But these broken AVI files will only become playable in VLC. If you try to watch the videos on another media player, you'll still encounter the same error. Along with this, the efficiency of the VLC media player repair process is also not always 100% reliable. Moreover, VLC doesn’t provide a permanent solution for the damaged AVI file, it only fixes the issue while playing the video.
