Sometimes when we record videos in phone or screen recording, copying or moving a video, or in some other cases, videos get corrupted. Has any of your important videos been corrupted? This one happens to me when I recording a video on my phone (Using Screen Recorder App) and my phone suddenly switched off. When I restart my phone and I open that video and it shows that can’t play this file. I used this method which I have written below to repair video file.

I needed that video, I tried some desktop software applications like **stellar phoenix video repair** etc. But most of them are paid software which required to buy them first to repair video file. I have written a way to repair video file, you can use it to fix your video. You have to use your computer or laptop.

## **Step 1**

You can [download this video repair tool](http://grauonline.de/cms2/?page_id=5) to repair video file. Currently, this software repair only these formats ( **.mov, .mp4, m4v, .3gp** ).It repairs video files that are truncated, broken, corrupt or damaged. Repairs videos/movies that were not finalized by the camera. You can repair wmv video files and other formats by converting it to .mp4 using any video converter software.

**Note** – Only 50% of the video length can be repaired in DEMO mode. You have to purchase the full version of the software to get 100% repair output. However, I have mentioned one way by which you can repair your video 100% without purchasing the full version.

## **Step 2**

Extract this software to any drive.

## **Step 3**

In the image below, you see two video files. These two videos are screen recordings of my phone. when I was recording my screen my phone suddenly switch off and video (v1.mp4) got corrupted. When my phone was restarted then I made the remaining screen recording of the video again (a.mp4). So, I want to tell you that if your video is corrupted while recording, copying, moving or due to some other issue, You will need two videos, a video that is corrupted/unplayable and a video that is playable and both these videos must be recorded from the same device/phone. So, I have two videos one is playable (a.mp4) and another one is unplayable (v1.mp4).

## **Step 4**

Copy video v1.mp4 and paste it into the same folder. I copied this video in the same folder because I am going to combine this two videos (v1 and v1-copy), As this software repaired only 50% of the video. Combining videos give you the complete output of your video.

## **Step 5**

Rename v1-copy and type it as v2.

**Note** – You need to have your video names v1.mp4 and v2.mp4.

## **Step 6**

Open the command prompt by typing Win+R and then type cmd and hit enter. Then type this command.

- Type **cd** and then hit enter (cd is used to change the drive)
- Type **f:** and then hit enter (My videos are in f: drive, if your videos are in some other drive then type the name of that drive).
- **cd videos** and hit enter (My videos are in the f: drive and the folder name is videos, suppose folder name is abcd in which your videos are stored then you have to type the command as cd abcd).
- Type **copy/b v1.mp4+v2.mp4** (this command combine v1.mp4 and v2.mp4 video at v1.mp4 and note that there is the space between b and v1.mp4).

## **Step 7**

Open the software that you have extracted. Open gs.exe and choose your language. Now, you see two option **choose movie** and **choose reference movie.** In choose movie option select the corrupted/unplayable video file and in choose reference movie select a playable video which is made from the same phone then click on scan and wait.
