Memories are precious, and videos are a powerful way of capturing and saving them with us forever. Whether you have used a professional camera or your mobile phone to record video, it always allows you to relive those moments by revisiting them time and time again. And sharing them with your friends and family on social media like WhatsApp, Facebook, Instagram, YouTube, etc. 

But what if your video becomes corrupt and unplayable? Yes, there are many ways through which you might lose your (MP4/MOV/AVI) video. One of the common scenarios is video corruption.

A user on experienced a most common video corruption error and reported it as follows:

After migrating a large number of MP4 files from one drive to another, they show up as unplayable in VLC. Specifically they show a duration of 0:00. I've been searching around on the net about this, and found a suggestion that I use VLC to rename the files as AVIs and then force repairs. That has not worked. In my research I see many offers of commercial software offering to fix these files, but they all seem to be from no-name vendors and I am very reluctant to download this software.

Below is the screen recording of a corrupt MP4 video clip that I experienced on my laptop, and it is showing as 00:00:00 in length, as reported by the user on the VideoLAN forum, despite the file size being 271 MB. In this article, you will find reliable solutions using which I repaired the corrupt video successfully.

Why is My Video File Not Playing?

Some of the most common scenarios under which your video might get corrupted are as follows:

  1. Encoding or Decoding Errors: Video encoding is a great way to compress large-size videos into smaller ones. Any occurrences of errors during the process of encoding or decoding a video file can damage your complete video.
  2. Improper Conversions: Most of the time, converting a video file is due to compatibility issues, but it becomes risky if we use an unreliable video converting tool. Additionally, it is important to be careful when editing videos to avoid corruption. Incorrectly implementing steps during video editing can cause video corruption, making the MP4 video unplayable.
  3. File System Errors: A file system on a storage device is responsible for organizing and managing files saved on your SD card or storage device. When it becomes corrupt, it leads to missing data. Any video file with missing data leads to corruption and playback errors like audio-video out of sync, MP4 file not showing video or audio, etc.
  4. Outdated Drivers: A driver on a PC is responsible for enabling communication between the hardware and the Windows operating system. If it gets outdated, then it creates compatibility issues resulting in video errors.
  5. Virus Infection: A virus or malware attack is a common way through which your files on a device get modified or corrupted. If your device gets infected, then all the files, including your recorded videos from the camera, get corrupted and playable.

Suppose you are a tech enthusiast who wants to repair your corrupt MOV or MP4 video file for free; in that case, this information is for you. However, it is advised to take a copy of the corrupted video file before implementing the below methods to avoid further damage.

Part 1: Convert Corrupt MP4 Video to Another File Format

Corrupt MP4 or MOV files might indicate issues like video playback problems, audio video out of sync, codec compatibility, or file header damage. By converting the corrupt video with VLC, you can leverage its capability to handle different codecs, including popular ones like H.264, MPEG-4, HEVC (H.265) for video, and AAC, MP3, and Dolby Digital (AC-3) for audio.

Most users might only know VLC as a reliable media player to play a vast number of video and audio file formats, but it can also fix video corruption. During the conversion, VLC attempts to fix errors and inconsistencies present in the damaged video and reconstruct missing or broken parts of the file, leading to a more complete and playable video.

1. Open VLC Media Player. Click on Media and choose Convert / Save option.

Once the corrupt video file is converted to a new encoded video format (H.264 video codec and the MP3 audio codec), you can play the converted MP4 video smoothly.

In case, if you are still not able to play your video, then follow the below method.

Part 2: Use Always Fix on VLC Media Player

The Always Fix feature in VLC automatically detects and repairs different types of video errors during the video file conversion process. Essentially, it detects and fixes common issues such as damaged frames, audio-video sync errors, and file header corruption, thereby enhancing the video playback experience.

Step 1: On VLC, select Tools and choose Preferences

Go to Preferences on VLC to fix the corrupt video

Step 2: Click on Input / Codecs tab.

Step 3: Under Files section, choose Always Fix. You can find this option in the dropdown menu of Damaged or incomplete AVI file and click Save.

If you follow everything that you just read, you should be able to play the MP4 file with no corruption. However, if you still find that your MP4 or MOV file has playback errors, then you should rely on the best video repair software like Remo Video Repair for repairing corrupt or damaged MP4 or MOV video files on Windows or Mac operating systems.

Solution 3: Online Video Repair Tool

Online video repair tools are typically effective for fixing minor video corruption, but they cannot fix severe or major video corruption or damage. Moreover, Online video repair tools are generally designed to address common issues such as audio-video sync problems, playback errors, or minor corruption that can occur due to file transfer errors or software glitches.

Important Tips to Avoid Video Corruption

  1. Always take a backup of your important videos on an extra SD card or on your hard drive or cloud storage devices like Google Drive, OneDrive, etc.  
  2. If you are capturing video on your camera, do not abruptly stop recording them. For example, do not remove the SD card from the camera while the recording is still in progress. Make sure to safely eject the SD card on the computer as well while playing any video.
  3. Use high-quality SD cards with fast write speeds and high storage capacities. For this, you can always check your camera's user manual to find out which SD cards are recommended for your camera model.
  4. Installing antivirus software on your PC or keeping your Windows operating system up to date can help avoid malware or virus threats to your files and folders, including videos. This is because antivirus software can detect and remove viruses that can infect your system and damage or corrupt your files.
  5. Avoid using unreliable tools to recover or edit any video file. Some unreliable video converter tools might not support the correct codecs or file formats. Thus making your videos corrupt while editing them.


Repairing a corrupt video file can be a challenging task, but thankfully it’s not impossible.
