Part 1: Reasons behind the Inaccessibility or Corruption of Videos

MOV is a container format developed by Apple to be used on QuickTime player. It stores videos, audios, texts, 3D, virtual reality, graphics, and animations. MOV files usually store video files in high quality and size although they are slightly larger than MP4 files. On the other hand, MP4 is also a container format developed by the International standard. It is an upgraded version of the MOV file format that works with different media players and also supports mobile devices and USB drives. The MP4 container comprises Graphics, video, subtitles, and audio data. The output file size and quality of MP4 are much better compared to MOV. The beauty of these video formats is that they can be converted from one format to another format.

Whichever file format you choose to store your videos they still face a threat of being corrupt when you mishandle them. MOV, MP4, and other video files get corrupted due to different reasons.

  • To begin with, they get corrupt when they are not converted properly to other file formats.
  • Or when you are editing or transferring videos, and there is a sudden system failure.
  • Videos are prone to damage when a virus infects your computer or the storage devices.
  • Also, when there is a power outage, and your computer shuts off immediately leads to the corruption of files.
  • System crash has also proven to be another major reason for videos getting corruption.

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:

Video Repair Mac

  • 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.

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.

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

Mac Tool Replacement

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

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.
