Two hundred and seventy characters is short enough to read in one breath, and it still makes six decisions. That ratio is what makes it the most useful prompt on this page to copy the shape of.
It opens with the camera. That is deliberate and it is worth adopting. The official prompt writing guide puts camera near the end of the within-shot order, but a prompt this short has only one shot, and leading with the move tells the model what kind of clip this is before it has decided anything else. Everything after reads as detail attached to a dolly rather than as a still that something later has to move through.
The move itself is written the way movement has to be written for this model: as plain English with a type and a rate. "Slow dolly forward" has both. "Cinematic camera work" has neither, and a phrase with neither leaves the model to pick a type, an amplitude and a speed on your behalf — three decisions you did not make.
The lighting clause is the one that repays study. "Practical lights only, wet cobblestones doubling every highlight" is two constraints in eight words. The first bans light sources that are not in the frame. The second tells the model that the ground is a mirror, which turns every neon sign and every cart lamp into two light sources instead of one. That is why a five-second clip from this prompt looks lit rather than rendered.
The sound half is three items long and every one of them is a thing you can see or infer from the frame: the wok on the cart, the rain on the awnings, the sign that is already described as buzzing. Because H3 Max generates audio in the same pass, sound tied to visible sources is sound that lands in sync with them.
And because fal publishes the parameters with this one, it doubles as a settings reference. 768P is the resolution the model is tuned around. Five seconds is the floor. Balanced is the expansion mode that decides per request how much to rewrite you, which keeps the total time close to the render time — quality can spend up to thirty seconds on the rewrite before rendering starts.
