A tiny Dubai skyline on a film set, hit by a controlled wave. Fifteen seconds, vertical, one prompt in Luma Labs.
It's a shot that either reads as a practical-effects miniature or as obvious AI. The difference isn't the prompt length — it's knowing what to check before you accept a take.
Understand the layout before you generate
The prompt describes a set, not a disaster: miniature buildings, visible studio floor, controlled water. Ask for "a tsunami hitting a city" and you get stock-footage chaos. Ask for a miniature under studio lights and you get the shot.
The four checks
After the first generation, look at exactly four things: scale consistency between buildings and water, whether the water behaves like water at miniature scale, camera stability, and whether the set edges stay believable.
If one fails, regenerate with a correction aimed at that one thing. A vague "make it better" reroll changes everything and usually trades your problem for a new one.
Then leave it alone
The temptation is to grade and add effects. This shot works because it looks captured, not processed. A light CapCut pass for pacing and sound is enough.
The guide has the complete prompt, the four checks in detail, and the correction phrasing for each failure mode.
