What resolution were the scans used for the official blurays? I don't know much about motion film, I've been scanning my still photo negatives at 4800 dpi and that works out to about 100mb a frame too. I would love to see a frame of motion film scanned at 4k (or 10k, wow!).
The official blurays were done at 1080p. They were originally for the DVD release.
