PromptEN449 characters
The black dress flares as she spins away from the glass wall, the slit opening the full length of her thigh, and she catches herself mid-turn and looks back over a bare shoulder into the lens. Snow bursts past the window behind her and the city lights smear through it. Her hair whips across her mouth and she pushes it back. Slow orbit around her as she turns, cold blue light against warm skin. Cinematic, shallow depth of field, heavy film grain.Written in English, exactly as we sent it.

Why this prompt works
The still already holds the burst at its peak — fragments frozen mid-explosion, one arm raised — so the prompt only sets it moving: the spin, the skirt flaring with the turn, a look thrown back over one shoulder. `duration_seconds` `4`, `aspect_ratio` `adaptive`; `generate_audio` is `true`, unlike most of this family. `resolution` `720p` keeps the flying edges sharp.
Settings used
| Setting | Value | What it does |
|---|---|---|
| resolution | 720p | 480p, 720p or 1080p, default 720p, and it feeds the billed quantity directly. Note that the output tier is independent of the source still: a soft low-resolution frame rendered at 1080p is just enlarged softness. The tier you pick is the render tier, with no upscaling or enhancement layered on top. |
| aspect_ratio | adaptive | Only `adaptive` is accepted here: Seedance 2.5 always frames an image-to-video clip on the geometry of the opening frame, and a fixed shape would make the task fail. If the delivery format is fixed, crop or pad the still to it before you send it. No effect on billing. |
| generate_audio | true | On by default. Produces a native soundtrack synchronized to the picture — room tone, movement effects, voice. Turn it off for product pieces that will be scored in post; leave it on when footsteps and ambience are part of the point. |
| duration_seconds | 4 | 4 to 30 seconds, default 5. The longer a frame-driven shot runs, the more it drifts — anatomy and set dressing deform gradually. Confirm the direction of the motion at 5 seconds, then extend. For genuinely long sequences, several shorter takes cut together usually hold better than one 30-second take. Length scales the billed quantity linearly. |
