What generative tools actually change
Every previous revolution in filmmaking lowered one wall. Portable cameras freed the frame from the tripod. Digital editing freed the cut from the razor blade. Generative tools lower a different wall — the one between imagining a shot and having it. A storyboard that talks back. A location scout with no plane ticket. Coverage of a scene you could never afford to stage.
What doesn't change is the underlying physics of story. An audience still needs a character to want something, an obstacle worth fearing, a reason to lean forward. A model can generate a thousand beautiful establishing shots; it cannot tell you which one your second act needs, because that answer lives in the arc, not the pixels. The bottleneck has moved — from access to taste.
When anyone can render anything, the scarce resource is knowing what's worth rendering.
The honest fear — that the flood of synthetic footage drowns out the good stuff — is real, and the honest answer is that it makes authorship more visible, not less. A distinct voice was always the rarest asset in the business. Now it's the only one.
