Due to a variety of reasons, DashCam videos may refuse to play or become missing. In critical situations, such as accidents, where the video files are vital in insurance claims, one cannot afford to lose those few seconds of video to prove their case.

This guide thoroughly explains the step-by-step solutions on how you can repair dash cam corrupt files and get them to play flawlessly. It provides tips on how you can make sure your DashCam videos don't get corrupted.

Part 1: Overview of Dash Cam Damaged Files

A dashcam is a video camera mounted on the car's dashboard or windscreen and continuously recorded through the windshield while driving. The camera saves video files, usually in MP4, MOV, AVI, M4V, file formats, on an SD card. You can transfer the video footage from the SD card to your computer and play them using standard video players.

Your dash cam may work just fine for years, and then when an accident happens and you need to review the footage, it appears that the video is missing or damaged, and the dashcam videos won't play. Besides the dashcam video not playing, they may turn blurry, become choppy or jerky, are flickering, frozen, grainy, have missing sound, or have audio-video sync problems.

Why? The error can either be with your dashcam, SD cards, or the often unintentional wrong handling of dashcam videos.

Part 3: How to Protect Dash Cam Videos

Manual fixes may fail to repair dashcam videos that won't play due to more serious corruption. Sometimes the best way is to take steps to avoid getting your DashCam video files corrupted.

To prevent your video files from being corrupted, you have to begin by understanding how DashCam files are stored. DashCams are designed to keep recording videos continually and, therefore, store videos in a manner that is slightly different from conventional cameras.

They record in what is called "automatic loop recording." This means that a DashCam records in an indefinite loop and continuously overwrites the oldest files with newer video files. The loop should start when you start your car and stop when you switch it off. All the videos are stored on an SD card that you can insert and remove from the DashCam. Steps that you can take to avoid getting your video files corrupted include the following.

Tip 1. Use the best memory card type possible:

If you use a slower SD card, your DashCam may have trouble writing data onto it, resulting in DashCam corrupt files. An 8 GB card only has a recording loop of fewer than two hours at 1080p resolution. This may result in excessive read/write cycles and video corruption. You should, therefore, use at least a 64 GB class 10 SD card.

Tip 2. Immediately lock your DashCam when an event occurs

The first thing you should do if you are involved in an accident is to use the emergency lock function on your DashCam and quickly remove the SD card. This will prevent the DashCam from powering on again and possibly overwrite the video's critical parts with new video data. After you have removed the SD card, you should put it in an SD card adapter and slide the switch on the adapter's left side to read-only mode. Doing that will ensure none of the memory card data is altered.

If you find videos lost from the SD card, you should read the guide for solutions - How to Recover Videos from SD Card.
- 2 minutes to read it.

Tip 3. DashCam shutdown and file writing

Under normal circumstances, if a DashCam loses power from the car battery, it should continue working long enough to record and save video files using its internal battery. Therefore, you should regularly check your DashCam battery to make sure it's charging and working at full capacity. If your DashCam battery is depleted or is not charging, a sudden loss of power can result in corrupted files.

Tip 4. Disable event detection

Most DashCams have an event detection function that senses shocks and immediately write-protects the last few seconds before the event. This feature is meant to ensure that the DashCam cannot overwrite videos of accidents or other damaging incidents. Problems usually arise when this feature senses minor incidents, like a door closing, and write-protects the file. This unnecessarily reduces the space available for the recording loop and, therefore, increases reading/write cycles.

Tip 5. Carry extra SD cards

Carrying a few spare SD cards is usually a good idea. If any accident or event occurs that you want to keep, immediately stop and swap the SD card in the dashcam to protect the video file from overwriting

If you were having a nervous breakdown because your dashcam videos are corrupted, I hope by now you have realized that it is nothing to worry about if you use the Wondershare Repairit to repair your videos in no time.
