How to repair corrupted A7S files?

That's what happened to Craig, one of our customers:

"Camera was recording in 4K, there was an external battery source used to power the camera. The power got unplugged before the camera stop record button was pressed. Then the MP4 can not be opened by camera or computer."

Fortunately, we were able to solve the problem and provide him the Repair Kit to fix the file.
See how was his experience recovering the lost shot in following video.

“If you ever have a video file that corrupts and you're looking for a solution, I highly recommend Aero Quartet”

Solution: Your Repair Kit, developed by our technicians

All models from Sony Alpha series are supported. No matter whether the files are recorded using FullHD or 4K resolution, or even using slow motion recording mode.

The damaged files cannot be opened because recording did terminate abruptly. While the media — video and audio — is present and not corrupt, the index and header of the movie indicating what the data means, is not present.

Data inside is encoded using a XAVC-S Video track along with a Linear PCM Audio track. Repair process consists of reindexing the video frames.
