BandiFix is a freeware that can repair broken video files. It is a free recovery software that can be used for fixing corrupt video files. It allows you to recover corrupt/broken AVI or MP4 files that cannot be played.
BandiFix can repair broken AVI or MP4 files that have undergone an abnormal termination when recording through Bandicam. It will also help recover other corrupt AVI files that were downloaded from the internet. On the other hand, you cannot fix MP4 files that have been downloaded from the internet.

A .bfix file is an index file that contains the index information of an MP4 file being recorded by Bandicam. This file is created and disappears automatically when you start or stop recording.
If Bandicam is abnormally terminated while recording due to power outage or other issues, open the output folder (see below), then double-click the .bfix file in that folder. The broken .MP4 file will be repaired by BandiFix automatically.



If you cannot find a .bfix file, please email the following two video files to bandicam@bandicam.com:
1. The corrupted video file.
2. Record a short video (approximately 10 seconds) using the exact same Bandicam settings as the broken file.
We will attempt to repair the corrupted file using our recovery tools. Please note that the estimated success rate is around 20–30%.
