How to fix corrupt MP4 files with Repairit’s Video Repair Tool

If you’ve got a damaged MP4 file, it’s not difficult to fix the video with Wondershare Repairit.

MP4 is the most common video format because it’s high quality but lightweight. It’s also compatible with the vast majority of video players. However, as with other files and formats, MP4 files can become corrupted in various ways, with unfortunate results. Audio and video may no longer synchronize correctly. Or the audio or video might disappear. Obviously, those are serious problems if you don’t have a backup.

Fortunately, Repairit makes fixing corrupted videos easy (see steps below). It allows you to fix MP4 files with all levels of corruption. The Advanced Video Repair function can help you repair seriously corrupted or damaged MP4 video files compromised by virtually any cause: changes in format, file header corruption, improper system shutdown, file read and write errors, virus attacks, improper download and compression issues.

Step 1: Add your broken MP4 videos.

Add MP4 video files to the Video Repair Tool. Add or drag the repaired MP4 video files to the repair list.

Step 2: Start repairing corrupted MP4 files.

Select the damaged video files from the list and click the Repair button to start the MP4 video-repairing process.
