About today’s outage

MP4repair.org has experienced today (October, 28th) a five hours outage.
We’re sorry for the inconvenience.

Such events are fortunately very rare, since May 2013 we hadn’t faced such a serious problem.
This outage has originated at our hosting vendor and is not specific to MP4repair.org, so the good news is that MP4repair.org has not been compromised. It has just been offline for a few hours.

Now everything is working again. Business as usual.

How to create a Virtual Mac OS installation to repair damaged video files on your PC

Despite MP4repair.org service is able to diagnose and repair almost any damaged video file, there are some times that an offline service would be a more comfortable option.
Especially when dealing with huge amount of damaged files, or when needing to repair large files recorded with heavy encoding formats, Aero Quartet‘s Treasured repair service would be the best choice.

For those who have some files to be repaired and unfortunately have no access to a Mac computer there’s a way to achieve same results on your PC. Virtualization is the key to the success!

Instead of creating a Hackintosh, in essence, this method will let you run Mac OS X from inside a program window in Windows. Basically you will need a dual-core (two core) processor PC with at least 4 GB of RAM and some software (see below list).

  • VirtualBox : This virtualization suite is free, and though it doesn’t offer official support for Mac OS X, it works pretty well to our purposes.
  • iAtkos ML2: The most popular Mountain Lion distribution that works with VirtualBox.
  • Multibeast 4.6.1 : You will need to use this patching tool to set up the Mountain Lion virtual machine after the initial installation.

A detailed step by step process can be easily followed in the guide posted by MacBreaker at their entry How to install OS X Mountain Lion in Virtualbox with iAtkos.

Assuming that all the set up is done and you already have your virtual Mac OS X environment up and running, we will concentrate in how to repair those files which format (XDCAM, ProRes, REDCODE, etc.) is not intended to be repaired using MP4repair.org service.

Basically the idea is to use same tools as if you were in a real Mac computer. That means you can use Treasured to diagnose your damaged file and even place a repair request from it. But keep in mind that here, the main goal is to repair your damaged files in your virtual environment, and once done, use them in your real workflow.

So, in case you did not already placed a repair request at MP4repair.org, then do it now using Treasured by clicking the  button.

In a few minutes you will receive a preview of your damaged file repaired and a quote for the repair. Finally once confirmed, you will get the required Repair Kit that will repair the files.

Repairing them should be as easy as open the Repair Kit (by double clicking it as any other Mac OS application) and selecting you damaged files.


Typically issues found are due the lack of the appropriate codec installed. This is quite normal as you just set up a Vanilla virtual environment with no Video codec at all but the stock ones. So it’s highly recommended that you take a careful look at Treasured‘s configuration pane to get an idea of the missing codecs (in below picture XDCAM codec should be installed).

Alternatively you can take a look at the Movie Repair Guide to know how to proceed to install any missing codec.

Finally keep in mind that now you’re running a virtual OS but the devices available on it still depend of the physical ones present in your PC. Therefore to use a card reader or a USB disk you would need to mount them inside the VirtualBox.

To do so just look for the  Devices list that are displayed and inside the USB Devices should appear the one you are looking for. Just click it and it will be mounted on your Mac desktop.

If you have any question or doubt during the whole process simply get in touch with our technicians at info@aeroquartet.com.


New Player in Sport Cameras

Seems that those who love recording their sport adventures in full detail are really lucky.
Geonaute has just announced the launch of its new 360º high resolution action sports video camera.

With a full horizontal range of 360 degrees and a vertical range of 150 degrees there’s little you will miss from the scene for sure.

No need to worry about focus or point the camera to the action. Everything will be automatically recorded. Later at editing time, you will be able to select the desired point of view. Ever wanted to know what was happening on your back when skiing down the hill?
Now you can with this camera!

It is a specially designed camera for extreme sports, waterproof (for surface activity, although it also has a special case for sports like scuba diving) and shock. It is quite lightweight (270 grams) and, although it has its own range of accessories also all the well-known GoPro ones can be used.

But as you can imagine, shit happens, and a hard landing or empty battery will leave you with a corrupt video. So whenever you need us, we’ll be ready to help you dealing with that cool footage lost.

DIY Dash Cam using your GoPro

Dashboard cameras have drastically grown in popularity ever since a video of a meteor falling through the sky in Russia went viral last February. While you may never catch a glimpse of a meteor, these cameras can be great for proving fault in an auto accident, or even making sure your teen is driving safely.

You can purchase a dedicated dash cam for under $100, but the video quality isn’t great and you can’t easily use the camera for anything else. Instead, the GoPro Hero 3 is a small, slightly more expensive HD camera that can go nearly anywhere, including the dashboard of your car.

With some slight modifications, the GoPro Hero 3 quickly becomes a trusty, high-quality dash cam. Here’s what you’ll need:

  • GoPro Hero 3
  • GoPro suction mount
  • USB charging cable
  • USB car charger
  • Power drill

First, remove the GoPro from its plastic housing and drill a hole into the side where the USB input is located. This will allow you to plug your GoPro in and charge it while you drive. Just don’t expect the housing to remain waterproof after you’ve put a hole through it.

Next, suction mount your GoPro to your windshield. For the best angle of the road, you may have to mount the camera upside down. GoPro offers an in-camera option to flip the image, or you can rotate it using the software that comes packaged with the camera.

Finally, plug one end of the USB cable into the GoPro and the other into your vehicle’s 12-Volt outlet via a USB car charger adapter.

Once you have your GoPro set up, simply turn on the loop recording feature. That’s the key of the recording process.

Loop recording is a new feature and is kind of mysterious at a first glance. If you set it for, say, 20 minutes you’ll always be able to stop the camera and have at least the previous 20 minutes recorded.

The way it works is by actually splitting the 20 minute duration by 4, and keeps 5 sets of these clips on the SD card at any given time. 4 of the 5 clips are 5 minutes in length (20/4) which equals the full 20 minutes, the 5th is the current one recording (until it hits 5 minutes). So if you stop after 44 minutes you’ll have 4 clips each 5 minutes long and one clip 4 minutes long. This is why I say you’ll always have at least 20 minutes (or whatever duration you set).

Now you can capture everything that goes on in front of your vehicle. And even if you don’t end up with a video of a meteor falling from the sky, you can always speed up your footage and make a cool time lapse of your favorite driving route.

In case crash happens and your cam got damaged your footage could be repaired using MP4repair.org services. Drive safely!

How to Repair Damaged .3gp Files

Imagine you took your daughter’s first birthday party on your mobile phone and when wanting to share it with your family, the video is no longer playing. Ouch! that’s what chief4life11 thought when posting for help. Fortunately we could help him bringing back the clip. Wanna know how? Just keep reading.

3GP file format is a compressed file format of a larger video file. It acts like a container where several video files of small storage capacity are stored. These files have extension of either .3gpp.3gp or .3g2.

Unlike any other file container, .3gp files are small in size and because of this feature, this file format is used frequently for small hand held devices like mobile phones. However sometimes users have to face the problem of being not playable due to deletion or corruption of such files.

There are several reasons for loss of 3GP video files. Most of the time culprit is the lack of space left on your memory card. Other times simply your phone got locked up and required a battery pull making the file not get properly saved.

Due to any of the unforeseen reasons file gets inaccessible and throws various type of error messages. In such circumstances, backup files will surely helps you a lot but in case it is unavailable then you can take the help of MP4repair.org to repair your damaged .3gp files.

Alternatively you could try to change the container using ffmpeg to copy the contents of the damaged .3gp file into a new mp4 container. Just type below command in your system’s prompt to get it done.

ffmpeg -i input.3gp -vcodec copy -acodec copy output.mp4

(Please note that you would need to have installed ffmpeg on your system and you need to change the name of the files shown to match your damaged files.)

Recover Deleted Videos on an SD Card (Part 2 of 3)

Part 2: Find Deleted Videos


In previous post “Recover Deleted Videos on an SD Card (Part 1 of 3)” we explained how to create a image file from a damaged card. Now it’s time to go on and see how can we access to the damaged footage and finally, repair it.

You should have a .img file with a size similar to the damaged disk capacity. If the disk still contained video, the footage must now be inside your file as well.

Your .img file will now be split into tiles, like an archaeological excavation grid. We will search for video inside each tile. Keep in mind that as well as in an excavation, lots of sand could be dig out before finding a bone. So same could happen with your deleted video.


1. Figure out how many tiles
If the average size of the video file that you want to recover is 500 MB, divide your .img file into tiles of 500 MB. For example, a 32 GB card will give you: 32000/500 = 64 tiles.

You can reduce the number of tiles in the first pass, then narrow down once you have verified that your footage is present.

2. Split your .img file into tiles
You can use free software like HJSplit to perform this task.


Tiles files will have same name as your original .img file by default, but adding a .00x suffix that will be increased according to the number of tiles created. In the example below, 8 tiles of 500 MB were created from an .img file of 4 GB.

3. Run MP4repair.org diagnostics on each tile
MP4repair.org is a web tool to preview and repair video inside a corrupt file. Diagnostics are free. By trying every tile, you will map all the video present in damaged disk.

In the example below you can see the first tile diagnostics results. Looks promising.

As suggested before, check all created tiles to find the footage you need to repair. To do this, simply click on the blue New Diagnostics button that is shown below the preview.

In case some tile shows No Media or simply a different footage you’re not looking for, just remove it from your cart by clicking the blue cross that is shown in the upper right corner of its list entry.



In this case, third tile file usb.img.003 is showing a different format and should be removed.

Once all the footage that needs to be recovered is found go on with the repair.


Don’t be afraid of the price shown during the tiles exploration. Final quote will be adjusted accordingly to the number of files to be repaired. Also keep in mind that Aero Quartet experts will keep an eye on the repair process.

Let’s see how to repair it in the third and last post of this series…
