Corrupted braw Files repair

PostFri Jul 23, 2021 8:14 am

Hi,

We had a 3 Day shoot with the Pocket 6K, the workflow for backing up data was identical all days.

On the last day after copying (with terra copy, checksumms checked) I could not load any of the BRAW files into Resolve but one Clip - out of 96. The filesizes look normal. I can import the other days. Simultaneously the SSD with the source material appeared to be unformated (was fat32) after the copying process.

So I am stuck here with 95 corrupted braw files. Is there a way to repair the header, or something because I believe the Data is there. I uploaded a file to aeroquartets Tresured Tool and the preview showed the clip. Is there another way of restoring the braws?

Help and suggestions are very much appreciated!

Thanks

Totally not mandatory part of support responsibility as it's not necessarily directly related to camera itself.
When you have corrupted hard disk do you go to eg. Seagate to recover your files?
No. You go to a company which specialises in recovery. Same here. If you really need it then you have to pay someone to try to recover it. Sometimes it's easy, but sometimes it's simply impossible. Not that cheap kind of service either. If it happens a lot then it may be faulty camera and then it's BM support problem.
BRAW is similar to mp4, so fix may be simple, but you have 0 guarantee it will be simple. BM could write some tool to fix missing headers etc. but they won't help everyone with their lost files for sure. Doing it manually requires knowledge and it's not necessarily that easy.

Have you tried any solution which goole shows you, eg.
https://aeroquartet.com/treasured/black ... aw.en.html

You can at leats check if files are recoverable.

A company called Aeroquartet repairs corrupted BRAW files, but they're not cheap. To fix one 5-minute clip is $119. The reason I'm responding here is to ask about other potential methods to repair these files on my own. Does anyone know what they're using and how to approach this?

In the past, I've used a text editor to open the video file and correct the header, but I can't use Notepad due to file size.

Any help or resources that could point me in the direction of learning more about this would be greatly appreciated. As of now, I don't even know what to search for.

Use any HEX editing tool- this will let you open big files.
I don't think there is other/better manual way.
If you have other recordings then compare headers and try to copy header from good file to bad one.
