Video Repair Tool

Do-It-Yourself Video Repair Tool (VRT)  –  MP4视频文件修复工具 – MP4 Repair

“We googled 2 days to find a solution to repair some broken .MP4 movie files – we couldn’t find one, so we
started to build our own.”

Our repair utility can repair and fix broken or damaged video files (MOV, MP4, 3GP, M4V) that do not play in your media player. Please check in our practical use cases if your video file issue is a mission for VRT .

What exactly means REPAIR? Repair means that only video and audio portions can be repaired that are not lost: On some of your corrupt files, it MAY NOT repair anything at all, on some files it MAY repair some video portions, and on some other files it MAY repair both video and audio portions (It fully depends on the grade of corruption).

  • Repairs video files that are truncated, broken, corrupt or damaged
  • Repairs video files that do not play in QuickTime or Windows Media player
  • Repairs movies that were not finalized by the camera
  • The repair does not depend on a valid/correct container format – the raw video and audio stream data is fully automatically reconstructed
  • Supports non-broken reference movies for finding missing movie meta-data and parameters

Currently, our software can automatically repair damaged .mov, .mp4, m4v, or .3gp movie files (generally, all movie files based on QuickTime container format) that use one of the following codec formats:

  • avc1 (H264/AVC, used by most digital cameras, HD video cameras, iPhone, etc.)
  • hevc (H265, used by modern digital cameras, video cameras etc.)
  • mp4v (H264/ISO, used by a few cameras)
  • MPG2 / xdvc / xd5d / xd5e (MPEG-2 / XDCAM, used by Sony cameras)
  • jpg (Motion JPEG,used by Panasonic cameras)
  • icod (Apple Intermediate Codec, used by Final Cut)
  • dvc / dvpp / dvhp (DVCPRO / DVCPRO HD, used by Panasonic cameras)
  • apch / apcn / apcs / apco / ap4h  (ProRes 4444/422/LT/HQ/Proxy, used by Final Cut)

Movies of the following cameras have been tested for correctness with our software (however we cannot test all camera models, and it generally works on most digital cameras):

Blackmagic URSA Mini 4.6KFor PCM audio, choose ‘Enable PCM detection’
Canon 60D, 5D, 7D, T1i, EOS 550D, Powershot SX20, S95For PCM audio, choose ‘Enable PCM detection’
Canon 574HDFor PCM audio, choose ‘Enable PCM detection’
Contour HD Helmet
DJI Mavic Pro, DJI Phantom Pro, DJI Vision Plus 2If video is stutters, choose ‘AVC1 single mode’ and ‘No CTTS repair’ under options.
Drift HD720Experimental: Choose custom repair parameters ‘-single’ under options.
Flip Ultra HD
GoPro, POV.HD, Contour+2, ActionPro X7If repaired video is hanging, try activating ‘No CTTS repair’ under options. If audio is missing, choose ‘Enable AAC detection’. If you recovered a GoPro/ActionPro video from an SD card media, your repaired video may freeze every few seconds. The reason is this camera stores additional files and your recovery software cannot filter out the additional files, and puts the data into the video files. Solution: use our data recovery tool (MaxDataGenius) to first extract the correct MOV files from your media.
iPhone, Nokia N82, Nexus One, all Android phonesIf repaired video quality is bad, choose ‘No CTTS repair’ under options. If audio is missing, choose ‘Enable AAC detection’ under options.
Liquid Image HD320, Toshiba Camileo S30, B10, P100,
AR Drone Quadcopter
Experimental: Choose custom repair parameters ‘AVC1 single mode’ under options
Kodak ZX1, ZX3, ZI8, Z7590
Nikon Coolpix P300Experimental: Choose custom repair parameters ‘AVC1 single mode’ under options
Olympus Tough TG-810Choose custom repair parameters ‘AVC1 single mode’ and ‘No CTTS repair’ under options.
Oregon ATC9K
Panasonic HVX200, HXDC1, DC-GH5If you have a corrupted .MDT file, use it for repair and rename it to .MP4 before running the repair. Choose ‘No CTTS repair’ under options if repaired video is hanging. If audio is bad, choose ‘Enable PCM detection’ under options. If video does not play at all, try option ‘Overwrite existing codec information by reference file’ . If importing of repaired videos does not work, reparied video must be converted after repair – reenconding/converting (using ffmpeg) for import is included in the program under options: If you choose ‘MP4 (same quality)’ it will use ffmpeg to convert the videos for import. Note: do NOT use Panasonic’s SD card file recovery (AVCCAM), the recovered MOV files are unrepairable. Solution: use our data recovery tool (MaxDataGenius) to first extract the correct MOV files from your media.
Samsung HMX200, HMXS10, MX20, SMX-F400BP/EDC and many other Samsung camerasExperimental: Choose custom repair parameters ‘AVC1 single mode’ under options
SIV M7Experimental: Choose custom repair parameters ‘AVC1 single mode’ under options
Sony XDCAM, EX1, F900,
JVC HM100,
Matrox MX02,
Other MPEG2 cameras
If audio is white noise, under options, choose custom repair parameter ‘-af twos’ for PCM big endian, or ‘-af sowt’ for PCM little endian.
If video is shaky, under options, choose:
1. Enable ‘reencode movie files’
2. Choose ‘Custom (ffmpeg) as ‘preset for reencoding’
3. Enter ‘mp4: -f mov -acodec copy -vcodec mpeg2video -sameq’ into ‘custom reencoder params’
Sony DSC-HX1Choose ‘Enable AVC1 single mode’, choose ‘Reencode repaired movie files (MP4 high quality)’, choose ‘Overwrite existing codec information by reference file’
Sony A6500, AX100, A7SII, A7RII, A7IIChoose ‘No CTTS repair’ under options. For PCM audio choose ‘Enable PCM detection’

Step 1: Add your camera model with a simple click here (we will update our software for your camera model as soon as possible)

Step 2: Verify that your camera model is supported by ‘reparing’ a non-broken sample file

If your camera model isn’t listed above, or the repair tool doesn’t seem to work with your movie, please first try the ‘repair’ using a non-broken (playable) sample movie of your camera to find out if the program fully supports your camera:

  1. Download the video repair tool DEMO version (.zip), and extract the downloaded archive by double-clicking it in the OS X Finder (Mac) or Windows Explorer (PC).
  2. Run the video repair tool by double-clicking the application ‘’ (Mac) or ‘gs.exe’ (PC).
  3. Click on ‘Choose movie…’ and choose a non-broken sample (playable) movie of your camera. Using a non-broken sample movie you can verify if the program fully supports your type of camera.
  4. Click on ‘Scan’ and wait until the scan finished (spinning cursor disappears).
  5. Click on ‘Preview’ to check if the movie could be ‘repaired’. If your sample file doesn’t repair, please send us a link to your non-broken sample movie (e.g. using some freely available online file sharing service such as or ask us for our FTP), so we can add support for your camera to the repair tool.

This approach ensures that there are not two issues at the same time (program does not support your model, and damaged files does not contain any data). If it properly supports your camera model, but doesn’t work on the damaged file, the damaged file is too broken for a repair.

After you sent us your sample movie, we’ll try adding support for your camera (this may take some weeks). All customer files are kept confidential.

Step 3: Your sample file repairs, but your broken movie doesn’t repair
If your sample movie correctly repairs (step 1), but your corrupt file doesn’t repair, we may check your corrupt file. Send us your corrupt movie (and one working sample movie of your camera) using an online file sharing service such as (up to 2 GB files),  (up to 5 GB files) or   (up to 30 GB files). After you sent us your truncated broken movie, we’ll examine it (this will take a few weeks). All customer files are kept confidential.  Please only send small sample files (max. 100 MB), as we do not have a fast Internet connection here.

Contact: Please always follow the two steps above to contact us via e-mail – Following those two steps is the only proper way we can help.   Click here to contact us!  NOTE: Due to the many requests we get, this will take time, and due to the many requests, we may not be able to answer to your specific request.

Part 2: Frequently Asked Questions about Playing 4K Videos

1. What is a 4K video?

A 4K video is a video that is recorded in the 4K resolution. The horizontal side of a 4K video has approximately 4000 pixels, while in most cases, 4K videos displayed on monitors and TVs have a resolution of 3840X2160 pixels. The movie industry standard is 4096x2160 pixels.

Ultimately, the 4K video’s resolution depends on its aspect ratio, as slight variations occur with either of the most commonly used aspect ratios for 4K videos. This, however, doesn’t affect the image quality.

2. How to play a 4K video on a PC?

You must install a media player that enables you to watch 4K videos on your PC in order to view 4K content. So, once you’ve installed a media player that can play 4K videos, you just have to open the video file with the media player of your choice.

In addition, you are going to need a 4K display to view the video in full resolution because HD or Full HD displays can’t play 4K footage in full detail.

3. Do you need a special media player for 4K videos?

At the moment, Windows and macOS don’t have a built-in media player that can play 4K videos. However, this is no cause for alarm because there are numerous media players you can install on either of these operating systems for free.

VLC or 5KPlayer are just a few options you will have at your disposal, but you should also keep in mind that you have to install appropriate codecs on your computer if you want to use it to watch 4K videos.

4. What is the difference between 1080p and 4K videos?

The total amount of pixels a 1080p and 4K video contains is not the same. Consequently, the amount of details a 4K video can depict is much more significant than on 1080p videos. That is also the reason why 4K video files are much larger than Full HD video files that contain significantly fewer pixels.

However, it is nearly impossible to spot a difference between a 1080p video and 4K video from afar, but as you zoom in, you will notice that pixelization occurs at different zoom levels.

5. Is 4K video available on YouTube?

Yes, it is. YouTube offers support for 4K videos since 2010, and you shouldn’t have too much trouble finding 4K content on this video hosting platform. In case you would like to upload a 4K video to your YouTube channel, you should arm yourself with patience since the duration of this process depends on the size of the file you’re trying to upload.

How To Copy Large Video Files to a USB Flash Drive or Other FAT32 Storage Device

Most of the time I deliver finished photos and videos to my clients via digital download. It’s quick, easy and saves me time and money by avoiding the hassle of uploading files to a physical storage device and sending it in the mail.

However, it is occasionally necessary to copy photography and videos to a USB flash drive for delivery to a client (some clients don’t have reliable high speed internet, some want a physical product, some don’t have a reliable PC and some are just not tech savvy enough to figure out how to download a large number of files from a link).

One issue that I have started to run into – especially with longer or 4K video – is transferring files larger than 4 GB to a USB flash drive.

Fortunately, the solution is relatively easy – here is how to copy files larger than 4 GB to a USB flash drive, memory card or other FAT32 storage device.

The Problem

Most USB flash drives (and memory cards) come pre-formatted with the FAT32 file system. While this is fine for day to day use, one key limitation of the FAT32 file system is that you cannot save individual files that are over 4GB in size.

Back in 1995 when the FAT32 file system was introduced, this wasn’t much of a problem – nobody had 4GB files! However, with 4K video, longer HD videos or ProRes / DNxHD video clips, exceeding that 4GB file size limit isn’t too hard to do.

If you try to copy a file that is larger than 4GB to a USB flash drive with the default FAT32 file system, you will get an error saying that there is not enough space to copy the file (even if its say a 6GB file being copied onto a 64GB USB flash drive with lots of room to spare).

The Solution

To solve this problem, all you need to do is format your USB flash drive with the exFAT file system.

exFAT has no file size limitations and is compatible across most modern devices including both Windows and macOS (although there may be some compatibility issues with older devices).

To format your USB flash drive with the exFAT file system: select the USB drive you want to format from your file explorer, right click and select “Format”, then in the format dialogue, choose exFAT under the File System drop down menu.

Warning! This will delete everything on the drive you are formatting, so make sure you have selected the correct drive and that you don’t have any critical data saved that you don’t want to lose.

If you are working in a strictly Windows environment, you could also format your USB drive to NTFS, but exFAT is more compatible across platforms and is specifically optimized for flash drives.

If you’re interested, here is a great article that explains the difference between FAT32, exFAT and NTFS.
