Makes you wonder what resolution of video could be encoded digitally if you used the entire frame. With compression algorithms and a good encoding method, surely the image quality could be improved over the standard analogue print.
There is actually a reason to do this - and people do. For long term archival film is king - it's store and forget, unlike hard drives that require migration every few years. So people write digital data to film, either in the form of text documents as images, or some digtal encoding of the data, and then it's put into long term storage.
GitHub did this with its Archive Program https://archiveprogram.github.com/, and Piql https://www.piql.com/ is a company that specialise in doing this. They're the company that created the Cinevator, a high speed data to film transfer machine that was originally used for creating film prints, but since film is kinda dead these days, they've pivoted to archival storage.
