PromptEN516 characters
Time is frozen: the rain and the wall of shattered glass hang dead still for a beat. Then the camera charges in fast and whips around her as she closes her raised hand into a fist; the suspended shards snap into a spiralling orbit around her, the frozen raindrops streak into long lines, and the whole shockwave blasts outward past the lens as the rain crashes down all at once. Her gown and hair whip in the blast. Extreme camera move, anamorphic flares, cold blue-white grade, shattering glass and a deep low boom.Written in English, exactly as we sent it.

Why this prompt works
The still frame does all the setup for the frozen time: raindrops stopped in mid-air, a shattered glass facade holding its shape as a motionless shockwave. The prompt only has to start it moving — she closes her fist, the shards spiral into orbit, and the whole wave blasts past the lens as the rain falls again. The camera charges in and arcs around her while several million shards each move on their own; this one is here to test the ceiling.
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 | 5 | 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. |
