Step 3. If your corrupted video is an AVI file, now you can simply try playing the corrupt AVI with VLC. If it is in other format, you need to rename the file extension of your corrupted video to .avi before importing it to VLC.

If it doesn't work, you can try converting your video to AVI instead of just renaming file extension. To convert video, you can still use VLC. You can’t find AVI preset from the drop-down menu of VLC Profile, but you can create an AVI profile yourself.

If you need a faster conversion, a dedicated video converter program like WinX HD Video Converter Deluxe might be a better choice. Supporting GPU hardware acceleration, this tool can convert any video to AVI at 47X real-time faster speed without damaging quality.

After transcoding video to AVI, try opening it again.

Well, above are the ways to repair corrupted MP4, MKV and other format videos with VLC. If none of them works, you may need to use professional video repair software.
