Whether you're a novice videographer or an experienced editor, corrupted files can occur at any time.

But don't worry, there is still hope! By understanding why such issues occur and applying the right methods and tools, you'll be equipped to fix damaged videos and get them running. In this article, we will discuss the most common causes of faulty videos and provide you with five simple yet effective methods to repair faulty video footages and make them playable again.

Potential Causes that Lead to Faulty Videos

To properly diagnose and repair corrupted video files, it's important to first identify what may have caused the issue. There are several potential reasons that are common sources of video file corruption.

Hardware malfunctions: Faults in hardware such as cameras, memory cards, hard drives or other storage devices can damage videos. Issues like bad sectors on a disk or damaged connectors introduce read/write errors that can corrupt data.

Abrupt shutdowns: Removing memory cards or accidentally shutting down cameras, computers or other devices while videos are still being recorded, edited or transferred interrupts the process. This leaves files in an unfinished state that can cause playback problems and faulty videos. 

Filesystem errors: Faults in file system like corrupt allocation tables, permissions errors or bad clusters can be a reason for faulty videos. Therefore, regular backups and file system checks can help in prevention.

Virus/malware attacks: Malicious programs can damage your files and sometimes target video files. Getting infected to malware introduces unexpected changes that interfere with decoding during playback. To avoid such issues, regular scanning of your devices and storage devices are a must.

Power outages: If power is unexpectedly lost while editing or file transfers or your battery gets discharged during recording, it can improperly corrupt videos, making them unviewable. Ensure uninterrupted power supply to avoid any issues.

Compression issues: Problems with the codecs, or settings used to compress and decompress videos lead to lost, corrupted or missing frames, audio sync issues, and other strange behaviors in a video file.

File corruption can strike even under normal usage from various failure. The key is to determine where a problem originated so the issue isn't repeated and files can be repaired when possible.

5 Methods to Repair Faulty Videos

Certain methods do exist to repair damaged and unplayable video files. Simple adjustments to playback settings, transcoding to an alternate format or updating media players can help to get the videos play. These solutions have the capacity to fix issues related to improper codec support, corrupt headers or indexing information.

1. Check and Adjust Playback settings

Many times video playback issues occur due to incompatible settings rather than video being actually corrupt. Try adjusting settings like screen resolution, audio/video tracks selected, etc., on your player to see if it helps resolve glitches. You can also try adjusting advanced settings like file caching or disc caching or metadata network access. 

• Open the problematic video file in the media player.
• Click on the Settings/preferences icon.

• Try changing things like resolution, audio track, network and file caching values, etc.
• See if adjusting any of these makes the video work properly.

2. Use the Video Fix Feature in VLC

• Play the video to check if it's working now.

3. Update Your Media/Sound Drivers

• Check for updates to your video player software.
• Make sure graphics/audio driver for your device is also updated.

• Download and install any available updates.
• Newer versions get improved codec support.
• Try playing the video again after updating drivers.

4. Use VLC for Transcoding Corrupt Videos

• Open VLC player.
• Select "Convert/Save" from the Open media menu.
• Click on Add to insert the faulty videos. Usually this supports MP4/MOV file format.

• In the Convert window, provide the file name and preferred destination for storing the file.
• Now, select the desired input codec from the Profile list.
