Film production requires resources of mainly budget, time, and available talent. The production technologies a good producer selects will strike a balance that does not strain any of those resources. So if there is a technology that offers some clear benefit to the production, and it will not drain resources to the extent of compromising other parts of the production, go for it. Otherwise, don't. I sense Black Magic could strain the resources of a real production, in that it is a very new technology that at some levels looks like it's built on a house of card. At the very least complicates post production, and on the set there is a higher than normal risk that some hitch might appear that could cost production hours or days. Job #1 is to deliver the production. Job #2 is don't look like a bunch of clowns on the set. But if you're just screwin' around, WTF! Sure looks good, doesn't it?
