Could someone please confirm my math and if I'm wrong show me where I'm wrong. I'm having this debate with someone.
My argument is that a 720P scan of a regular 8 frame is approximately a 5200 dpi scan. A regular 8 frame is .137 inches high. So...if there is 720 dots per .137 inches then that is equal to about 5200 dots per full inch making that a scan resolution of 5200 DPI on a regular 8 frame. This would make scanning at 720P of regular or super 8 film and upscaling to 1080P virtually indistinguishable from scanning directly at 1080P from such a tiny frame.
Thanks
