Do your dash cam videos fail to play, display error messages, or have freezing or skipping? This issue compromises the reliability of important recordings you may need for insurance or other purposes. We provide a detailed guide on how to diagnose and fix corrupted dash cam videos. Trust our expertise—we offer methods that we have personally tested, which have successfully fixed various types of corruption.
Signs That Your Dash Cam Video is Corrupted
First, we would like to provide you with the basic signs to help you identify corruption in your dash cam recordings and then choose the most appropriate method to fix it.
- If the video fails to play across various devices—be it the dash cam itself, computers, phones, or tablets—and the media player displays error notifications like “cannot render the file,” this serves as a clear sign of corruption. Such issues occur because the video file likely lacks necessary data or contains damaged data that media players cannot process. Most media players rely on specific data structures within the video file to decode and display the content. The player cannot execute the playback function if these structures are corrupt or incomplete.
- Another common indicator of a corrupted dash cam video is discrepancies, such as out-of-sync audio and video streams, pixelation, and unexpected flashes or stripes of different colors during playback. These artifacts usually result from errors in the video compression process where the data encoding the video and audio streams suffers corruption. This might occur due to abrupt disruptions during recording, such as power losses or memory card issues, which lead to incomplete or incorrect data being written to the file.
🔴 Note: If the video does not play on one particular device, the problem may be caused by a codec incompatibility rather than corruption. Installing a third-party media player capable of supporting a broader range of codecs might resolve the issue in such instances. This solution often allows the video to play back successfully on devices where native players fail.
4 Solutions to Repair a Corrupted Dash Cam Video
If you have confirmed that your dash cam video is corrupted, now is the time to examine how to fix it. We present four methods to tackle corruption within dash cam video files. Pay attention to the fact that each method addresses specific corruption scenarios, so it is important to review all of them before you decide which one to apply.
🔴 Note: In the sections below, we will outline only the basic methods; however, you can find more methods to repair corrupted dashcam videos on the web if you seek more custom solutions.
Method 1: Try to Play the Video File on the Dash Cam Again
When you first notice that a video does not play on your dash cam, restart the device and attempt playback once more. Users on forums often report that this simple action can address issues with videos that stopped recording unexpectedly. If the dash cam managed to create a file, it might try to finalize it upon restart, typically it results only in the loss of the last few seconds of footage.
If your dash cam successfully plays the video after restarting, the next step is to copy the file to your computer. This action will help you determine if the video plays on other devices to confirm the file’s integrity and playback capability. This method offers a quick initial test to salvage video files without complex procedures. It provides a simple solution to recover important recordings.
Method 2: Use an Online Video Repair Tool
The simplest way to fix a corrupted dash cam video often involves an online video repair tool. This method saves time and makes the repair process easier. We recommend Clever Online Video Repair, a tool well-suited for addressing issues where necessary playback components like the moov atom or metadata have been lost due to interruptions during recording. It supports over ten video formats, including the most commonly used by dash cams—MOV and MP4. The main advantage of Clever Online Video Repair is that it offers its services free of charge.
🔴 Note: For this method to succeed, you will need a reference file—a video shot on the same dash cam with identical settings. If you possess such a file, copy it to the device you plan to use for the repair. If you lack a suitable reference file, record a new one under the same settings.
- Prepare your corrupted dash cam recording and the reference video.
- Open a web browser and navigate to the Clever Online Video Repair website. Locate and click the ‘Choose file’ button to upload the corrupted video.
- A prompt will appear asking you to describe the circumstances that caused the dash cam video to be corrupted. You can provide details or skip this step and proceed directly to the repair.
- Select your dash cam’s brand and model from the dropdown menus. This information is typically in your vehicle’s manual or the dash cam’s packaging.
- Following the corrupted video, upload your healthy reference video to help the tool accurately repair the corrupted file.
- Sign up for an account, which you can do conveniently with your Google or Apple account, to initiate the repair process.
- Once the repair is completed, preview the frames of the fixed video. If you are satisfied with the result, proceed to download the video.
- After you download the repaired video, it is advisable to play it on any standard media player to confirm the repair was successful, and the video plays back correctly.
Method 3: Use the Repair Function of the VLC Media Player
For videos with minor corruption issues, such as indexing problems, VLC Media Player offers a reliable solution (indexing issues generally involve errors in the video file structure that disrupt the playback sequence, which makes the video difficult to watch). While VLC is widely recognized as a versatile media player, it also features a built-in function designed to automatically fix minor corruptions in AVI format videos. For videos in MP4 and MOV formats, you must first change the file extension to AVI before you proceed with the repair process.
- Locate the corrupted video file in your file explorer. Right-click the file, select ‘Rename,’ and change the file extension from .mp4 or .mov to .avi. Confirm the change to update the file format, which makes it compatible with VLC repair.
- If you don’t already have VLC Media Player installed, download it from the official VLC website. Then, follow the installation instructions to set up VLC on your device.
- Open VLC Media Player. Navigate to ‘Tools’ > ‘Settings’ in the VLC menu.
- Under ‘Input/Codecs,’ select ‘Always fix’ from the dropdown menu to enable automatic repair. Click ‘Save’ to apply these settings.
- Use ‘File’ > ‘Open File’ to locate and play the renamed AVI file. VLC will now attempt to fix the video during playback using the ‘Always Fix’ settings.
- If VLC successfully repairs the video and it plays correctly, you can save the corrected version.
- Click on ‘Convert/Save’. Choose your desired output format and specify a destination folder to save the file. Click on ‘Start’ to export and save the repaired video file to your chosen location.
Method 4: Re-encode the Dash Cam Video
If your dash cam video plays but displays visible artifacts such as pixelation, audio desynchronization, or color issues—problems we identified earlier—it may be necessary to re-encode the video. Re-encoding involves decoding the video’s data to an uncompressed format and then encoding it again into a new compressed file. This process can correct errors that occurred during the initial encoding and potentially bypass corrupted segments of the video.
While online converters offer a quick way to re-encode videos, they often have file size limits. Since dash cam recordings can span several hours, these tools may not suit your needs. A more powerful solution is HandBrake, a free, open-source software that can convert video files without size restrictions. It allows for detailed adjustments in video encoding settings, which helps maintain the quality of long dash cam recordings.
- Visit the official HandBrake website to download the software. Make sure you download the version compatible with your operating system. Then, follow the installation instructions to set up HandBrake on your computer.
- Launch Handbrake, click ‘Open Source,’ and select the corrupted dash cam video file you wish to re-encode.
- Choose the desired output format from the presets available or customize the settings according to your needs. Verify to select a format that supports your playback requirements, such as MP4 for compatibility across various devices.
- Choose a preferred location to save the re-encoded video.
- After you set up your output preferences, click ‘Start’ at the top of the Handbrake window.
- Handbrake will begin processing the video, which might take some time depending on the file size and your computer’s processing power.
- Once Handbrake completes the encoding, view the new video to check it plays correctly and the previous artifacts are no longer present.
Conclusion
In this article, we have outlined four methods to repair corrupted dash cam recordings that work on both Mac and Windows. These methods have been successful in our experience. However, the effectiveness of these techniques may vary based on the specific condition of each video file. For example, if a video has lost its visual track and only the audio remains, it is likely permanently lost. Additionally, if you often face issues with corrupted dash cam recordings, it’s a good idea to check the SD card used for storage. A damaged SD card can disrupt file structure and lead to recurring problems. Regular checks and replacements of your storage media can prevent future data loss and provide the integrity of your recordings.
