Final prompt (paste into Veo / Gemini / Flow):

Premium commercial look, photorealistic, vertical close-up at counter height of a matte black ceramic pour-over coffee dripper with a thin polished copper rim, sitting on a clear glass carafe on a walnut kitchen counter by a window in the early morning just after sunrise. A thin stream of dark coffee trickles from the dripper into the carafe while soft steam curls up from the rim, and the dripper and carafe turn a slow quarter turn. Slow dolly in, 85mm-style telephoto feel, shallow depth of field with the kitchen background in soft bokeh. Soft low-angle morning sunlight from a window on the left with gentle fill and a warm rim light catching the copper, palette of matte black, warm copper, honey-brown walnut and soft cream highlights, calm and quiet mood. Real-time pace; the final second holds still on the dripper's front.
Audio: close, clear sound of coffee trickling into a glass carafe, a faint soft drip, quiet low morning room tone, no music.

Before

A cool cinematic shot of a woman drinking coffee in a nice cafe, make it 10 seconds.

After

Style: Contemporary 35 mm film look, natural and understated, soft contrast, fine grain, warm-neutral grade.

A small neighbourhood cafe on a quiet weekday morning. A woman in her early 30s with shoulder-length dark hair tied loosely back, wearing an oatmeal knit sweater, sits alone at a round marble table by a large street-facing window. In front of her: a white ceramic cup of black coffee on a matching saucer and a folded paper napkin. Behind her, out of focus, a wooden counter with an espresso machine and a barista moving between shelves of cups. Thin steam rises from the cup and catches the window light.

Cinematography:
Camera: medium close-up, eye level, from across the table at a slight angle; slow dolly-in
Lens: 50 mm feel; shallow depth of field, sharp on her face and the cup, background soft
Lighting: soft morning daylight through the window from camera left as key; warm tungsten pendant glow from the counter as background fill
Palette anchors: cream, warm walnut brown, soft white, muted sage, coffee black
Mood: calm, quiet, unhurried

Actions:
- She wraps both hands around the cup and lifts it slowly (first two seconds).
- She blows lightly across the surface, then takes one small sip.
- She lowers the cup to the saucer and looks out the window with a faint, relaxed smile (final two seconds).

Background Sound:
Low hiss of the espresso machine, soft clink of cups at the counter, muffled murmur of a few voices; no score.

What changed and why

- Removed "make it 10 seconds". Duration is an API parameter, not prose, and 10 is not a supported value (4, 8, 12, 16, 20). Set `seconds: 8` in the call; the prompt now fits 8 seconds of action.
- "Cool cinematic shot" became a named style. A specific aesthetic instead of a vague adjective, set first so it frames everything else.
- "Drinking coffee" became three timed beats. Lift, blow and sip, lower and look out. Beats with timing cues are far more reliable than a single vague verb.
