Movies routinely have 8 or 9 digit budgets, with teams of hundreds of people who have to collaborate to make footage coming from dozens of different cameras look seamless and consistent. Meanwhile, $1M would be an insane budget for a photo shoot.
You can see this in the actual skills of people working in the field as well. Anyone working in video has a solid understanding of the technical underpinnings of their craft. On the other hand, it’s not uncommon for working photographers to not understand some really basic stuff about color science/data formats/etc.
