3 Best Methods to Repair Corrupt MOV Files on Mac

Let’s cut to the chase: your video is corrupted, and you want it fixed as soon as possible. To get the best repair results in the shortest time, follow the methods below in the order presented. This way, you start with the simplest and most effective solutions before moving on to more complex and less likely-to-succeed options.

Method 1: Use a MOV Video Repair Tool for Mac

Video repair tools are specialized software designed to analyze the structure of your MOV file, identify corrupted sections, and attempt to bypass them. (Note: these tools do not restore lost video frames.)

You have two main types of video repair tools: online services and offline (downloadable) software. Each comes with its own advantages and disadvantages:

• Online tools are typically easier to use and don’t require installation (so you can use them even on mobile devices), but they may pose privacy concerns since you’re uploading your video to a third-party server. That’s why it’s extra important to choose a reputable online video repair tool and just the first one you stumble across.

• Offline tools offer more privacy and control, but they can be more complex to use and may require some technical know-how. Also, many need to be installed, which is something users who don’t have administrator privileges, such as those trying to repair MOV files on a library computer, can’t do.

Let’s look at the two best online and offline video repair tools, one from each category and both completely free:

Option A: Use Clever Online Video Repair Service

Option A: Use Clever Online Video Repair Service

Clever Online Video Repair is one of the best completely free online solutions for fixing corrupted MOV files, particularly those caused by improperly terminated recordings or interrupted downloads.

The tool is extremely simple to use and can repair videos up to 5 GB in size. It supports a wide range of formats, including MOV, MP4, 3GP, 3G2, M4V, M4A, M4R, M4B, FLV, F4V, F4A, F4B, GIFV, and QT. If you have multiple videos to repair, that’s not a problem—Clever Online Video Repair won’t limit you, even after repairing dozens of files. This makes it an excellent choice for users who need to fix multiple corrupted videos without spending a dime.

Unlike many similar online tools, Clever Online Video Repair takes user privacy seriously. All uploaded videos are automatically deleted from their servers, so you can feel confident that your private content won’t linger on an unknown server.

To use Clever Online Video Repair, you need to:

1. Visit the Clever Online Video Repair website and drag your MOV video file onto the designated area.

   

2. Provide a healthy sample video recorded by the same camera and using the exact same settings as the video you’re trying to repair. You can use an older video from your archive or record a new one to a different storage device than the one on which your corrupted video is located.

   

3. Download the repaired video file to your computer.

   

You will be asked to sign in or create a user account to access the repaired video.

Option B: Try Untrunc

For those who prefer an offline solution, Untrunc—with its optional graphical user interface (GUI)—is a solid choice. This open-source tool can repair MOV, MP4, M4V, and 3GP files by using a working video file as a reference.

However, the GUI is included by default only in the Windows build. macOS and Linux users need to build it themselves, which can be challenging even for advanced users.

That said, you can still use Untrunc on macOS via Terminal. While it’s not as convenient as a graphical interface, it’s a workable solution if you’re comfortable with command-line tools. Here’s how to do it:

First, download the latest version of Untrunc (download ZIP from GitHub). Next, download the latest version of Libav. Unzip both, and make sure to place the Libav contents inside the libav folder in Untrunc.

1. Open Terminal, navigate to the libav folder inside the Untrunc directory, and run the following commands:

   cd untrunc/libav

   ./configure

   make

   cd ..
   

   

2. Now, compile Untrunc. In the main Untrunc directory, run:

   g++ -o untrunc -I./libav file.cpp main.cpp track.cpp atom.cpp codec_*.cpp codecstats.cpp codec.cpp mp4.cpp log.cpp -L./libav/libavformat -lavformat -L./libav/libavcodec -lavcodec -L./libav/libavresample -lavresample -L./libav/libavutil -lavutil -lpthread -lz

3. After successful compilation, you can now use Untrunc. Place a working MOV file and the corrupted MOV video in the same folder. Run the command in Terminal:./untrunc working_file.mov broken_file.mov

   

4. If successful, Untrunc will create a new file named something like broken_file_fixed.mov that you can then try to play.

While it may require a bit more effort than online tools, Untrunc can be very effective, and it won’t cost you any money to try it.

Method 2: Change the File Format to AVI and Play It Using VLC

This method involves a bit of file extension trickery and leveraging VLC Media Player’s built-in repair capabilities. It’s not guaranteed to work for severely corrupted files, but it’s quick, easy, and free to try.

Here’s how to do it:

1. Make a copy of your original corrupted MOV file. We’re going to be messing with file extensions, and it’s always better to be safe than sorry.

2. Take your copy and change its file extension from .MOV to .AVI. For example, “corrupted_video.mov” becomes “corrupted_video.avi”. To do this on a Mac, you can right-click the file, select “Get Info,” and then change the extension in the “Name & Extension” field.

   

3. Download and install VLC Media Player from its official website. VLC is available for all major platforms, but only the Windows, macOS, and Linux versions have the repair feature we need—the mobile versions, for example, won’t help you.

4. Launch VLC and open Preferences/Settings in the top-left corner of the screen. Navigate to Input/Codecs tab. Look for an option called Repair AVI Files. Make sure the option is set to Ask for action or Always fix.

   

5. Try playing your renamed file in VLC. If the Repair AVI Files option is set to Ask for action, you will also need to confirm the repair process. With any luck, VLC will repair the file and play it without any major issues. Unfortunately, I wasn’t lucky, and VLC didn’t manage to repair my video, as the screenshot below shows.

   

Note: You might notice some skipping during playback. This happens because the method instructs VLC to play whatever data it can detect in the file, even if the structure isn’t perfect. While this trick has successfully rescued many videos in the past, it isn’t flawless.

Method 3: Re-Encode the Video with HandBrake

Re-encoding involves decoding the existing video data and then encoding it again from scratch. This process can often bypass corruption issues and essentially rebuild the video file’s structure.

For this method, we recommend HandBrake. It’s a powerful, open-source video transcoder that’s completely free and highly capable, which is why it’s widely loved and frequently recommended across forums and online Q&A communities.

Here’s how to use it:

Download and install HandBrake for macOS from its official website.

1. Launch HandBrake and click on “Open Source” to select your corrupted video file or drop it into the designated area.

   

2. Choose a preset. For general use, “Fast 1080p30” is a good choice. You can adjust the Constant Quality slider in the Video tab if you want to. A value between 18-24 usually provides a good balance between quality and file size.

   

3. In the Save As field, give your new video a name and choose where to save it.

4. Click the Start Encode button to fix MOV video file on Mac.

Tip: If HandBrake fails to make your video playable through re-encoding, consider giving Shutter Encoder a try. It’s a solid alternative to HandBrake, featuring a user-friendly interface and a range of impressive capabilities.

How to Use Recovery Software to Recover Videos Lost During Recording Interruptions

Sometimes, the problem isn’t corruption at all—your video may be missing entirely because the logical references pointing to its physical location on the storage device were never recorded. Since no file is visible, there’s nothing to repair.

In these cases, you first need to recover the missing MOV file using data recovery software such as Disk Drill.

Disk Drill is user-friendly yet powerful, capable of recovering lost video files in a variety of scenarios. It supports a wide range of formats, including MOV, and can recover files from virtually any storage device—your computer’s hard drive, an SD card from a camera, or even a USB flash drive.

Here’s how to recover your missing MOV files using Disk Drill:

1. Download and install Disk Drill for macOS from the official website.

   

2. Connect the device where your video was being recorded (e.g., camera, phone, or memory card) to your computer.

3. Launch Disk Drill and select the connected device from the list. Click the Search for lost data button to start scanning.

   

4. Once the scan is complete, use the file type filter or simply type “.mov” into the search bar to display all MOV files Disk Drill found. You can also preview the videos to locate your lost recording. However, if the video is severely corrupted, you may only see the MOV icon in the preview, as shown in the screenshot.

5. Select the video you want to recover and click the Recover button. Finally, choose a safe location on your computer to save the recovered video.

   

It’s important to understand that while Disk Drill can often recover lost videos, success is not guaranteed. The sooner you attempt recovery after an interruption, the higher your chances of success.
