Lesson 2 of 22
The two-artifact rule
Script plus composite is the whole spec. If the video layer is deciding things, you skipped a step.
A finished ad spec is two things: the script (what is said, in what order, with what beats) and the composite (the starting frame — who, where, what light, what camera position). Together those are complete. Nothing else should be left to chance.
The video model's job is narrow: take that spec and execute it with fidelity and performance. It is not there to decide what the room looks like, how far away the camera is, or whether there's a second person. Every time you leave one of those to the model, it invents — and invention is where the AI tells come from.
The practical test
Read your spec and ask: could two different people produce meaningfully different videos from this? If yes, the spec is incomplete and the gap will be filled by whatever the model likes. Usually that means tighter framing, prettier sets, and extra hands.
This is why the rest of this course is ordered the way it is. Chapter 2 nails the script. Chapters 3 and 4 nail the composite. By the time anything reaches the video model, there should be nothing left for it to decide.
Takeaway
Script + composite = the complete spec. Anything you don't specify, the model invents — and its instincts are wrong.
