PromptEN376 characters
She holds the look back over her bare shoulder, then turns and continues up two more steps, the velvet train dragging heavily behind her across the marble, her gloved hand sliding along the brass banister. The chandelier flares a little brighter and the gilt catches, deep shadows swinging across the wall. Slow dolly following her up the stairs, hushed hall reverb, no music.Written in English, exactly as we sent it.

Why this prompt works
Almost the whole frame is black with one chandelier holding the highlights, and the shot is a following dolly up marble stairs with a velvet train dragging behind. Heavy fabric in motion and a moving light source together are the expensive part; the audio is left on for hall reverb rather than music.
Settings used
| Setting | Value | What it does |
|---|---|---|
| resolution | 720p | Output resolution: 480p, 720p by default, 1080p or 4k. ByteDance's own Seedance 2.5 renders natively at most in 1080p, so the 4k tier here is delivered by an extra upscaling pass on top of that native render — it is upscaled output, not native 4K, and the extra pass makes the task slower than 1080p at the same length. Resolution selects a rate tier and governs the delivered format only — it adds no detail the first frame does not already have. Higher tiers mean bigger files and longer renders. |
| generate_audio | true | Whether a native soundtrack is rendered in sync with the picture. On by default. Switch it off for silent loops, for material you will score in post, and whenever you are only checking framing. |
| duration_seconds | 5 | Length of the finished clip in whole seconds, 4 to 30, default 5, and the billed quantity — the charge scales directly with it. Thirty seconds is a lot to ask of one opening frame: confirm the motion short, then extend only what holds together. |
