And the second is to embed the recovered video and audio streams into the final MP4 file. At this point, we recommend that you copy the second command into a text document so you can run it later.

To do this, run the command that you previously saved in a text document. This command will call the FFmpeg tool to merge streams.

It has a wizard-like interface and is much easier to use. It was created by a video blogger who was able to recover MP4 files using the tool:. The chance of successful video recovery in these cases depends on how fragmented your MP4 files are, and whether you have overwritten the deleted files. And it is almost certainly impossible to recover deleted video files from an SSD drive. This chapter will be useful mainly for those who have deleted their MP4 files from a flash memory card such as SD or microSD.

Fragmentation of files occurs due to the way most file systems work. Each storage device, be it a flash memory card or hard drive, is divided into small blocks.

When a file is written to storage, the file system splits the file into small chunks that are placed in blocks. However, blocks of free space are not always aligned continuously. This is a fairly common case where blocks of free space are in between some other files that you have previously written to the storage medium. So, when you save write some new video to a storage device, its file system fills all those free space gaps with a new file.

As a result, chunks of your MP4 video file may be scattered across the storage. Sometimes there can be hundreds or even thousands of file fragments, depending on how fragmented the storage is. Now, when you delete a file or do a quick format, the file system does not actually erase the file, but rather deletes the indices that indicate where all the chunks of that particular file are in storage. To recover such a fragmented MP4 video file, one would need to analyze the whole storage medium to collect all the file's chunks and then combine them frame by frame into a single video file.

Pro tip: Quickly format your memory card before shooting important footage. This ensures that no unnecessary data is left on the card, and new video files are written into contiguous blocks of free space, rather than scattered around the storage. So far, we are not aware of any software that could accurately recover such fragmented video files. But there is still a solution:.

If you accidentally deleted an MP4 file or quick-formatted your memory card, the first thing you should do is remove the memory card from the camera and lock it to prevent new data from being written to the card. Remember — the less manipulations you do on the memory card, the higher the chances of recovering your MP4 files. Now create an image of the entire memory card. Upload the image file to a file sharing service like Google Drive and email us the link to it.

Our video engineers will analyze the image of your memory card and try to recover the video files for you.
