Steam That Talks
Density is the clock. Fresh or forgotten — the steam says which.
The brief
Steam whose density and speed encode temperature, and therefore elapsed time — a fast dense column early, a thin hesitant wisp later, in the same frame.
Why it's hard
The model renders identical decorative steam throughout, so temperature never changes and the passage of time reads as nothing at all.
Let the effect narrate. Volume encodes temperature, temperature encodes time, and no dialogue has to say it.

Starter prompt
Built with the CEMI MediaMax system for Google Veo 3.1. Prompts stay in English — that is the language these models take instructions in. Treat it as a starting point and start varying it.
Static handheld two-part shot, 65mm at f/2.4, a café window table on a grey mid-morning. A smeared water glass and a crumpled paper napkin sit in the dirty foreground. A thick-walled stoneware cup of black coffee rests on scratched zinc: at first the steam rises as a fast, dense, sharply defined column that leans hard when a door opens off frame. Time passes in the same frame; the same cup now gives only a thin, hesitant, intermittent wisp that dies twenty centimetres up, and a dull cooled skin has formed on the surface. Density is the clock — the shot says forgotten without anyone saying it. Backlit by the window so the vapour reads white against a dark interior. Hirokazu Kore-eda's patient domestic observation. The operator shifts weight once. Vintage glass, warm rendering, gentle halation on the window edge.

Steam carries information for free if you let it: volume and speed encode temperature, and temperature encodes elapsed time. Putting both states in one frame turns the effect into a piece of narration that no dialogue or caption has to do. The cooled skin on the surface is the corroborating detail that keeps the model honest about which state is which.
Identical thick decorative steam in both halves of the shot, so the temperature never changes and the passage of time reads as nothing.
