PromptEN187 characters
Time passes over the same rooftop: flat grey dawn warms to low amber, shadows stretch across the gravel, laundry on the line begins to move as the wind picks up. The camera does not move.Written in English, exactly as we sent it.

Why this prompt works
The two keyframes are one rooftop shot twice — flat grey morning, amber sunset — so the model covers a transition it already has both ends of. The prompt adds what a still can't: shadows stretching, laundry catching wind. In the output the laundry sits pale under dawn light, then moves and warms to gold by the close, the water tank holding its place. `resolution` is `1080p`.
Settings used
| Setting | Value | What it does |
|---|---|---|
| resolution | 1080p | Output resolution, 720p by default and reaching 4k; no upscaled tier is offered here. It sets a rate tier, and higher tiers mean bigger files and longer renders. It governs the delivered format only and adds no detail the source frame does not have. |
| aspect_ratio | 16:9 | Output framing, `adaptive` by default: the clip follows the ratio of the image you supplied, which removes the pre-crop step and keeps the subject away from the edges. Choose a fixed ratio only when the placement format is already set; the still is then centre-cropped to it. No effect on billing. |
| generate_audio | true | Whether a native soundtrack is rendered in sync with the picture. On by default; switch it off for silent loops or when sound is added in post. |
| duration_seconds | 10 | Length in whole seconds, 4 to 15, defaulting to 5, and the billed quantity. Pass -1 and the model picks the length itself: the estimate assumes the 15-second maximum and the final charge follows the delivered length. A shot driven by one frame drifts further the longer it runs, so confirm the motion at 4 or 5 seconds, and build longer pieces from several takes cut together. |
