Repair MP4 file - how it works
Broken MP4 files can sometimes be easily repaired so that the video can be played back without errors. We explain how to do this in this guide.
Repair MP4 file with free tool
A quick and free solution to repair your damaged MP4 file is the "Digital Video Repair" tool.
- Download the Freeware Digital Video Repair and install it on your PC. You can find the download at the bottom of the page.
- Start the program, click on "Input File" and select the damaged video file.
- With a click on "Repair!" the tool creates a repaired video file on your hard drive without overwriting the original file.
Alternative: Repair MP4 with shareware
If the tool does not bring the hoped for success, you can also try a trial version of the "Video Repair Service". With this, however, only half of the video can be restored; you need to purchase the full version for a complete repair.
- Download the Video Repair Service.
- Unzip the archive and double click on "gs.exe" to start the program.
- With a click on "Choose Movie ..." you can then add the defective video file.
- After clicking the "Scan" button, the file is examined and then repaired.
- Once the repair is complete, you will see the video in the list below.
