Commercial Movies: Film vs Digital
Not in modern terms, but the BBC did this for years. Many a series was shot multicam video on a sound stage, with any location footage shot 16mm, for portability. The blend was anything but seamless. My take on this was a mock scene from such a series... Woman: "What's it like outdoors?" Man, peering through window: "Hmmm. It's a bit soft and quite grainy."
