I have BRAW footage shot on my BMPCC 6K Pro, dumped to an external drive, that no longer exists on the cards. Somehow (oi) the footage wasn't reviewed before the card was wiped and shot on many times over, so going back to 'original' camera files isn't an option.
The 'corrupted' BRAW files (the whole card's worth) all play in Davinci/BRAW player, but when they do, there are random colored horizontal lines of varying sizes/widths which 'dance' across the video (changing every frame). The sound seems intact. I've tried using a HEX editor to compare the corrupted files to working BRAW clips, but I'm in over my head - I think the headers are intact. Especially odd is that the BRAW clips do open and play, just with digital noise on top of them.
I've managed to accidentally recreate the issue. It seems to appear when I transfer BRAW clips onto this particular external HD, and only occasionally. TerraCopy gives me the 'hashes mismatch' error. Unmounting the drive and restarting the computer seems to fix the issue, allowing for a normal transfer of the footage.
Has anyone else run into this? Does anyone have a solution or recommendations on how to recover? I have several clips that are distorted in this same way and would love to find a solution to recovering these files that doesn't cost arm+leg.
