How to Fix Corrupt Videos - MP4, AVI, MOV, MPEG, ETC.

In this video, I show you how to effectively repair a corrupt video file.
Typically the video file is corrupt since the device failed to save the header information. You can use hex edit to copy the healthy header from another working video, or you can use Grau Video Repair Tool to automatically add the header information as well as repair the other portions of the video. Both methods have worked for me in the past.

Steps:
1.) Try copying only 99.9% of the video.
2.) Process and see if it is successful in repairing.

Hope that helps!

You're a genius David :D
Thanks for making this tutorial bro!

Spent half a day searching software online to repair my 3GP video file from an Android phone that got corrupted after the phone switched off during the recording due to low battery.

Grau was the only software I did not use even after downloading it because it really looked suspicious and even though I have sandboxie I did not want to take the risk.

After your video I saw that it was trustworthy after all and the way I recovered the entire video perfectly with the free version was by combining your 2 methods :)

I used the Hex editor and duplicated the contents of the corrupted video before inserting it to Grau and after that it recovered the full video instead of just half.

Thanks a million, another one will not bite the dust ;)

Could you explain 2:00 a bit more in detail? I've tried manually copying everything but that makes my corrupt video the same file as the healthy reference video. So I just need that header but I don't see how to easily copy-paste only that info that's needed to play the corrupt file with the codec/settings from the healthy file. Thanks!

the program doesn't work for me. I've tried scanning it several times, but when it's done, it doesn't say that anything was repaired. am I doing something wrong?

[corks]

wow it actually worked... wtf, my GoPro got wet as soon as i went underwater as it was in its case (yes, it was sealed and everything) ... the gopro broke but this helped save the file i really needed! i'm super hyped this worked

Does NOT Work on Mac. Every time you open the GS File it gives you a script error.

i went to a 2 day airsoft event and my gopro wire (hooked up to external battery) gets snagged and ruins footage.

i didn't understand your copy and paste header information? you said to copy header info from healthy video to corrupt video but you copied from currupt video and saving in the pc? please explain the process again. please

Need more details on step 5. How do I know what, where to copy from the healthy video? What part is the header info?

[dknecro]

everything worked up to where my repaired video is suppose to be located in the repair folder. Inside that folder i have just the 2 chrome html files. does anyone know why i dont have a finished video in that folder?

[tone]

how do you save the doubled length video to an mp4 file from the hex editor

[karizproductions]

I still cant get it to play any other advice. I have tried copying headers into healthy video but no luck. thanks

Does it work with corrupted video files from data recovery?

[gibranmohammad]

But the repaired video's audio was not synced properly....can you help?

[ScreaminModelKits]

I switched data from computers but accidentally rebooted, now I have all the pics, but only half the videos play, the other half won't, VLC and windows player don't work :?

[TheHondaOutlaw]

So it kinda worked, but the video is all jumpy and has no audio?

[TheFrantastic]

The software doesn't do anything when I try to repair a file

[thememphis]

Hi, David. I tried to backup my gopro video based on your video. However, I cannot get any sound for it. Do you have any idea?

[fatboyprojects]

[fbifido]

From @1:59 you did not show what was copy and from where?       

can you do that part in a new video?

[geeyanchanel]
