Corrupt MP4 files can be played using a VLC media player. But for that, one needs to install the VLC media player app. On most desktops, the application comes pre-installed. To play a corrupt MP4 video file:
1. Select the corrupt .mp4 video file.
2. Right-click on the selected file and a drop-down list appear, select “Open With” and select VLC player. Usually, the video file will start playing.
The VLC media player is not just a player, you also can use it to rip a DVD, convert video, and more. It provides an in-built index repair feature that resolves issues and repairs movie file indexes instantly. AVI files can be fixed easily using VLC as the option that comes built-in with the app.
If the above steps don’t work for the MP4 file, or if the file is extremely corrupted, then the next steps can come in handy:
1. You can make a copy of the MP4 file that needs to be fixed. Then, right-click on the MP4 file and choose “Rename”.
2. Change the file extension to “.avi”, and hit Enter.
3. Download and install the VLC media player. Then, launch the VLC software on the PC.
4. From the “Tools” menu, select “Preferences”.
5. In the Simple Preferences window, click on the “Input/Codecs” option; the settings window for Inputs/Codecs will roll open.
