Q3: How are video files damaged?


A: Most often, video files are damaged as a result of interruption of the recording process.

This can happen if the battery is suddenly discharged while shooting a video. Or if you turned off the camera before stopping recording.

Other examples include: faulty memory card, broken camera or dropped device, damaged camera in a car accident, water damage, drone crash, and other types of breakdowns.

Another common problem is when a video file was accidentally deleted and then restored using some "undelete" tool, but as a result, the "restored" file does not play.

In most of these cases, Restore.Media can repair damaged video files, provided the actual video data remains in the file.

We recommend that you read our detailed guides for each case to improve the chances of recovering your specific files.



Q4: I cannot download the recovered file due to disconnection. What can I do?


A: Use a download manager that can resume the file download process if the connection is interrupted.

We recommend using the Free Download Manager:

https://www.freedownloadmanager.org



Q5: What types of video file corruption can you fix? How does file recovery work?


A: Restore.Media can repair video and audio files with damaged headers.

Such files usually look like regular video / audio files, have the correct size, name and extension, but you cannot open them in any media player.

Headers in video / audio files contain information about the media format, indexes, and other metadata needed to play the files.

Restore.Media scans the video and audio tracks in the damaged file, determines their format, collects information about any missing or damaged metadata and indexes, and then recreates the file header.



Q6: What is a sample file and why do you need one?


A: Different cameras record media in different ways, even if you select the same settings.

To recover a damaged video file, Restore.Media needs information about the entries in the file's metadata, which are usually unique for each camera model and settings used to record video.

Since these entries are missing in the damaged file, Restore.Media can take them from a good playable file recorded with the same camera and with the same settings as the damaged file.

As a sample file, you can use a good file recorded just before the broken one (if you haven't changed your camera settings). Or write a new file with the same settings as the damaged file.

An inappropriate sample file is the most common cause of video recovery failure. For a detailed guide on how to choose the correct sample file, see this article.



Q7: What is the size of the sample file required to repair a damaged file?


A: The size of the sample file does NOT affect the quality of the recovery.

The recommended sample size is around 100 MB.

In this case, uploading the sample will not take much time, and the data in the file will be enough to restore the damaged video or audio file in automatic or manual mode.



Q8: I accidentally deleted a video file and then restored it with a data recovery tool. However, I still can't play it. Can you help recover such a video?


A: When recording video to a memory card, such as an SD, the file is usually split into fragments and saved in available blocks of free space, scattered throughout the memory card.

After deletion, the sequence of fragments of the video file is lost.

Most common data recovery tools can usually locate and recover only the beginning of a video file correctly. And of course, such a file will not play.


Generally, we can restore such a file so that it plays again. But it can contain many artifacts and fragments of other files.


Keep in mind that Restore.Media may not always be able to correctly repair a video file "recovered" after deletion.

This is because we only repair missing headers and indexes in the files.

But if the source video data in the file has been corrupted, there is little we can do.


The solution in this case can be the correct recovery of all video fragments from the memory card. For more details on how to do this, read our guide to recovering deleted video files.


Also note that some cameras (such as GoPro 4 and newer, Xiaomi, DJI, etc.) record multiple files at the same time, resulting in the files becoming highly fragmented.

We have special filtering algorithms for these cameras. When uploading such files, indicate that they were recovered after deletion.



Q10: The recovered GoPro 4 or Xiaomi Yi video contains artifacts every 3 seconds. Can you fix this?


A: Some cameras, like GoPro 4 and Xiaomi Yi, record two video streams simultaneously. One in high resolution and the other in low resolution for preview.

Both streams are recorded simultaneously, which leads to significant fragmentation of the file system on the memory card.

If the MP4 file was deleted and then recovered using some “undelete” tool, it will most likely contain fragments from both streams.

High resolution video parts will be shuffled with fragments of video in low resolution, creating artifacts in the image. The sound will most likely be duplicated.


Restore.Media has an algorithm that allows you to filter out garbage fragments from such video files.

To activate it, please select the option – "This file has been restored from the media after it has been deleted or the media has been formatted".

Please note that it is not always possible to filter out low-resolution fragments and synchronize the audio with the resulting video sequence.


If this option does not work, try another data recovery software that can more accurately restore the sequence of file fragments. Or send us a message detailing the problem and our engineers will try to help.



Q11: What about the privacy of the uploaded video files?


A: The video files you upload are recovered automatically.

No one will view them unless you explicitly make a request for our engineers to manually restore the files.

When you create a request to restore a file in manual mode, only in this case, our engineer may need to review a part of the file to determine how it can be repaired.



Q12: How long after uploading will the file be stored on the Restore.Media server?


A: You can delete any file you uploaded as well as recovered files at any time. Just delete the recovery task in your account and all associated files will be deleted too.

If you don't delete the files yourself, they will be removed automatically 7 days after the last action associated with the files in your account. In this case, both the original damaged file and its repaired version will be deleted at the same time.


Before the automatic deletion, you will receive an email notification, so you can save the files if needed.


Please note that we keep the sample files you uploaded for one month in your Restore.Media account, so that you can use them again to repair new files. You can manually remove sample files from your account at any time.



Q13: I was recording a game screencast. But the file got corrupted somehow. After recovering it, I hear distorted sound. How can I fix this problem?


A: Unfortunately, this cannot be fixed automatically. However, we can try to fix the sound distortion manually.

Most likely, the file contains 2 audio streams. We can try to split the streams, given that one of the streams contains no sound, but silence. However, if both streams contain sound, unfortunately there is nothing we can do.

Please always double check your settings when recording game screencasts.



Q14: I don't have a sample file and cannot record it. What should I do?


A: In this case, at the stage when Restore.Media will ask you to upload a sample file, you can instead upload any MP4 file.

For example, you can record a few seconds of video on your smartphone and use it as a sample file.

Most likely, Restore.Media will not be able to recover the damaged file in this case.

You will see a page with a report, where Restore.Media will inform you that the file has not been restored. On this page, click on the button "Ask for a manual recovery by an engineer".

Our engineers will do their best to find a suitable sample file or manually repair your damaged file.



Q15: I paid to restore the file, but after downloading it, I noticed artifacts in the repaired video. What should I do?


A: Please always check the preview of the repaired video before paying for the service.

We provide screenshots taken at the beginning, middle and end of the video, as well as a full-length preview of the recovered file.

If you notice any artifacts in the preview, select the option "Ask for a manual recovery by an engineer".

Our engineers will help you fix damaged video fragments.

If you have further questions, please contact us at: info@restore.media



Q16: I have recovered a deleted video, but the file size seems smaller than the original and cannot be played. Can you help?


A: This problem may be due to the fact that a part of the deleted video file was not recovered.

Our engineers can try to recover all parts of the deleted video from your SD card manually.

To do this, we need an image of your SD card (full copy in RAW format).

Please note that we will be able to recover the deleted video only if it has not been overwritten by other files.

Therefore, it is important to safely remove the memory card from the device as soon as you discover that a video file has been accidentally deleted.

For more detailed instructions, read our article on how to properly create an SD card image and recover deleted video files.



Q17: My GoPro HERO 6/7/8/9/MAX video freezes. Can you fix this?


A: There is a known issue with GoPro HERO 6/7/8/9 and MAX cameras where the video freezes at some point and you can only see a still image.

Unfortunately, this cannot be fixed as the still image is all the camera actually recorded. The problem is most likely caused by moisture that may have gotten inside the GoPro while you were changing the battery or SD card.


The only recommendation here is to avoid replacing the battery / SD card while near water or in cold weather. Make sure your GoPro battery is fully charged and there is enough free space on your SD card before going outside to take some great shots.


For more information on the issue, visit the GoPro support forum for HERO 6, HERO 7, HERO 8 and MAX.



Q18: I have recovered a voice memo from iPhone, but the duration should be much longer. Can you recover the entire file?


A: The iPhone Voice Memo app usually caches the recorded data before it is written to the phone memory.

If the recording process is interrupted unexpectedly, the Voice Memo application may not save the data from its cache to the iPhone memory, and the data will be lost.

In this case, the iPhone may mistakenly display the expected audio file size. Whereas in reality the damaged file is smaller due to the lost part of the audio recording in the application cache. Unfortunately, this part of the file cannot be recovered.


After repairing the file, Restore.Media shows the percentage of recovered data. If this value is close to 100%, it means that all the data in the file has been restored, regardless of the file size displayed by the Voice Memo application.



Q19: My GoPro HERO video gets jerky if I shoot with stabilization on. Can you fix this?


A: There is a known issue with video stabilization on some GoPro HERO cameras. If the stabilization function is active, distortion in the form of jerking frames may appear in the captured video. This is how the camera records video. Unfortunately, this cannot be fixed.


The only advice here is to try updating your camera's firmware and then testing it with stabilization enabled.

Here's a detailed guide on how to update your GoPro firmware.

You can also find more information on this issue on the official GoPro forum for HERO6 and HERO7 cameras.
