> What cameras shoot uncompressed 8K HDR video? That doesn’t even seem possible given current SSD bus speeds.

12-bit bayer RGB matrix 8k @24 fps: 7680 * 4320 * 12bit * 24/s = 1.2 GB/s uncompressed. Currently SSDs go up to 3 GB/s. And you could have a RAID 0 array made out of multiple SSDs.

So it is possible. Entirely another matter whether it makes sense.

One hour of video at this bitrate requires 4.3 TB.

Did you forget that there are multiple color channels? 12 bit should be 36 bit so even more is needed.

No. That's how practically all of the cameras work. Google RGB bayer matrix.

There's just one color component per pixel, thus 12-16 bits per pixel is enough.
