Do-It-Yourself Video Repair Software (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.
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.)
- 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):

Help / Quick Start
- Download the video repair tool archive (.zip), and extract the downloaded archive:
a) PC: right-click the downloaded .zip file in Windows Explorer, and choose ‘Extract all…’.
b) Mac: double-click the downloaded .zip file in the Mac Finder.
Then go into the extracted folder.
- Run the video repair tool:
Double-click the file ‘gs.exe’. On some systems, it just shows ‘gs‘. That’s the executable to run. NOTE: If you get a message (‘missing script file’), the .zip file hasn’t been extracted properly (check step 1).
Double-click the file ‘gs.app‘. On some systems, it just shows ‘gs‘. That’s the executable to run. For Mac OS X 10.8 or higher: Right-click the app, and choose ‘Open’.
If you get a message (‘missing script file’), the .zip file hasn’t been extracted properly (check step 1).
- Click on ‘Choose movie…’ and choose your broken movie.
- Important: Click on ‘Choose reference movie’ and choose a non-broken (playable) movie of the same type. This is a required step if the broken movie is damaged (in most cases).
- Click on ‘Scan’ to start the repair.
- Wait until the repair has finished (the spinning wait cursor disappears). If the repair was successful, the found video clips can be found in the listbox. Click on one movie clip and choose ‘Preview’ to play back the repaired movie clip.
NOTE: If the repaired movie appears very choppy, try to load another reference movie of the same camera.
NOTE: Support for some cameras is experimental (see camera table at the top of this page how to enable experimental support for them!).

Do you have a camera or model that is missing in the software (not listed) or doesn’t seem to repair?
Step 1: 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:
- 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).
- Run the video repair tool by double-clicking the application ‘gs.app’ (Mac) or ‘gs.exe’ (PC).
- 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.
- Click on ‘Scan’ and wait until the scan finished (spinning cursor disappears).
- 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 www.wetransfer.com 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 2: 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 www.wetransfer.com. 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.
