Whether you are a professional filmmaker, movie fan, hobby creator, or just someone who wants to watch a video on a PC, then seeing a warning message instead of an expected visual scene won't make you happy, but this article brings hope back!
It is much more to get a corrupted video file than you may think. Sometimes, you can use an r repair tool to recover your data. Still, knowing the reasons can help you to prevent the next failure.
Let's go through the whole process of video creation and mark some potential pitfalls:
A recording is nothing else as saving clips and metadata. In most cases, visuals do not cause much trouble. On the contrary, metadata is more vulnerable to damage. It takes more time to create it.
Your recording device may have finished capturing the beauty of this world. But the metadata ingestion continues after the filmed action has ended. If something breaks in, the video file disintegrates.
You are shooting. An exciting scene absorbs you so much that you forget to monitor the battery level. Or you know it was low but cannot do anything about it at the moment. Your camera turns off while the video is being recorded.
Cameras fall and crash, especially those installed on a drone or Go-Pros and dashcams. Even if the camera does not seem to have a single scratch, the integral parts may become loose.
Camera teams working outdoor are also familiar with such hazards as heat and humidity.
Apart from the video-related causes, storage issues may corrupt the footage. You may have used a damaged or improperly formatted memory card in your camera. The card slot may have problems. When a card gets almost full during the shooting, the last recorded video will appear as corrupted. You exhaust the storage before you saved the complete data.
Oddly enough, playback of already saved files on the recording device may lead to corruption.
File transfer between storages may fail for multiple reasons, mostly lousy network connectivity and loss of power. Shutting down one of the devices during the file transfer corrupts your videos as well.
If you managed to move your footage files safely, it is still too early to relax. Permanent storages may have bad sectors due to some physical damage. You may notice that the video has compression or formatting issues.
Once you have your footage on a final device, please treat it with care. You should preferably not reboot or shut down your OS or device during the video is played.
Converting the file into other formats has potential risks.
An unlicensed video editing software may cause file corruption. When you open your video in a third-party player, it can change the background's meta-data without informing you. After that, you cannot play the video anymore.
Something uncontrollable, like a malware attack, can happen. Last but not least, time pressure or little experience may lead to human errors. Imagine that you do a lot of multitasking with thousands of applications open at once. You click around and manage to open your video file in a text editor and type a few letters into it. If you save it without reverting the changes, then you will be reading this article soon!
Before moving to solutions, let's put it all together. In most cases, you can repair video file online, independently on the underlying cause:
When you first realize that your videos have a problem, first of all, do not panic. If you saw that the camera went off, do not take the card out of it. Change the battery or plug the camera into a power source. It may help.
After the camera is on again, and the recording and saving have stopped, you can proceed.
Instead of dealing with recovering lost data, try to avoid these pitfalls.
As a last resort, you may turn to look for a corrupted MP4 video and MOV video repair online.

VLC works as a video player and is a free MP4 video repair available online for download without any license costs.
In many cases, VLC will play a slightly corrupted video file without throwing you a warning at all. Its library of codes allows the opening of damaged videos that a less armored player won't cope with reading.
If you have some other video player set as default, you can just right-click on the video file to open it in VLC.
If no miracle happens, you can try three basic approaches:
As you can see, before repairing the MP4 video online or fixing the online MOV video with any other tool, you need to exhaust the repair capacities of VLC.
Let us start with the cache. Currently, the memory cache of VLC can store only 1,5 seconds of the video snippet. Increasing this number may help when your video keeps freezing due to some corruption.
Open the VLC player preferences.
Find "Show All" in the bottom left corner.
In the "Stream output" section, set the new cache value.
If this fails to open your video, you've got a chance to change the default video output module. Repeat the previous steps to view the foldable menu again. This time, find the "Video" section. Then go to "Output modules" and try different modules.
Each time you switch to the new module, try to open your video. Then turn to the next.
If the output preferences do not seem to change anything, it's time to convert your .MOV or .MP4 into .AVI. Create a duplicate of the original damaged file and try the next solutions on the copy. By using a new copy for each of the two workarounds, you'll be on the side.
To make the file conversion meaningful, you need to activate some in-built VLC magic first. You can do it in Preferences.
Choose the "Input / Codecs" tab from the top.
From the "Repair AVI Files" drop-down menu, select "Always fix." Do not forget to hit "Save."
Now, try to play your new .AVI file normally.
You can convert the file by simply renaming it. Right-click on it, then select rename and change the file extension to .AVI.
Your OS will probably argue with you a bit: just click "Use .avi." Now, you can try to play it again. If this dirty fix fails, try to convert the file into the .AVI format from inside the VLC player.
In the player, go to the "File" menu and select "Convert / Stream."
Use the "Open media" button to open your file system and pick up the copy you've reserved for this try.
Click the "Customise" button to access the output profiles.
Select "AVI" and click apply.
Now, just choose a destination for your output file. Click on "Save as File."
The interface will change, and the "Browse" button will appear:
Select a file name and hit "Save." Try playing it with VLC.
Still, no guarantee it will work. But if you want to discover new bright sides of the VLC player, you may practice with those workarounds.
Indeed, you may have too little time for so many steps. There is another mp4 fix online that is worth trying.
