Corrupt BRAW

Hello partners. I would like you to advise me with this problem. Recently, in the middle of a recording (and the shot was really good) my BMPCC 4K's battery died. Already sitting in my study I discovered that this shot cannot be read, even though it occupies about 800Mb. I can see the cover images of the rest of the shooting, but not this one, in which I only can see the BRAW icon. I imagine that this is an error in the closing of writing of the recording.

I know there are software to recover other professional photo and video files. The question is: does it exist for BRAW? Any help will be greatly appreciated!! Thank you!

I can't help with this issue directly. But I can suggest looking into updating the camera's firmware. In my tests on the P4K, I didn't lose any files at the end of battery life. Things only went weird when I pulled the AC without a battery installed, something the camera can't "plan for".
