"Once the card was recovered, an exact binary image of it was made so investigators could examine its contents. They discovered, however, that the data was encrypted, and would require encryption keys stored in the camera's CPU, which was broken. Authorities contacted the manufacturers of the different hardware parts used in the camera, and with their help, were able to use surrogate parts to extract the data."
"Authorities contacted the manufacturers of the different hardware parts used in the camera, and with their help, were able to use surrogate parts to extract the data. They eventually recovered 12 still images and nine videos from the SD card,all at 4K resolution or higher. But it turned out that there wasn't any footage taken during the accident, since it appeared that the camera had been configured to offload its data onto an external storage device on the submersible's onboard computer, which was destroyed."
Investigators recovered a single SD card intact from the OceanGate Titan wreckage inside a titanium‑cased SubC Rayfine Mk2 Benthic Camera rated to 6,000 meters. The camera's optical sapphire window protected the interior despite a shattered lens and damaged internal hardware. An exact binary image of the SD card was created, but the data was encrypted and required encryption keys stored in the camera CPU. Manufacturers provided surrogate hardware to extract the keys and unlock the data. Recovery produced 12 still images and nine videos at 4K or higher, but no footage of the accident because onboard offloading moved recordings to a destroyed external storage device.
