A drone operator (UAV pilot) flies for establishing shots, landscapes, and some commercial work. Renting a drone without a pilot is how Nepal productions lose aircraft and permissions. Hire the operator; they usually bring the aircraft they know.
Confirm local rules, no-fly zones, and whether the location (heritage sites, airports, crowds) even allows flight. Pair aerials with a cinematographer so the look matches the rest of the film. CineGrid lists drone operators and drone equipment when vendors list them.
