Best use cases

Locked camera city scenes (camera_fixed)Product shots with controlled motion (clean, repeatable takes)Smooth continuity with end frames (I2V resolves / match landings)Repeatable looks with seed control (variant testing)Short ads and social clips with audio on/offMoodboards / key beats before longer edits

Why Seedance 1.5 Pro is powerful

  • Camera-fixed stability (Lock the camera for steadier motion and cleaner results in city/product scenes)
  • Seed control for repeatability (Reuse a seed to iterate without the look drifting — great for campaign variants and A/B hooks)
  • Start + end frame control (I2V) (Provide an optional end frame to guide how the shot lands (transitions, match cuts, clean finishes))
  • Native audio in the same render (Generate dialogue, ambience, and SFX in one pass — or toggle audio off for silent drafts and post finishing)

How to Write a Great Seedance 1.5 Pro Prompt

Seedance 1.5 Pro API Docs

Seedance 1.5 Pro performs best with clear subject/action, controlled camera direction (often camera-fixed), and concise audio notes when audio is enabled.

Tip: duration + aspect ratio are set in the UI — your prompt controls subject, action, camera, lighting, style, and sound.

Quick prompt (fast iteration)

Use 1–2 sentences when you want variations.

Quick = variations. Use for fast iteration.

Template (copy/paste)

[Subject] [one clear action] in [setting], [framing], [lighting/style].
Audio (optional): [ambience + 1 key SFX OR one short line].
Negative: no text, no logos, no subtitles/overlays.

Example

Handheld smartphone UGC clip of a woman unboxing a new skincare bottle at a kitchen table. She peels the seal, smiles, and turns the bottle toward camera. Soft window daylight, natural colors, subtle room tone + packaging crinkle.

Seedance 1.5 Pro • Text-to-Video • 12s • 16:9 • Audio: on • camera_fixed: true Director brief: Cinematic locked-off night city shot after rain. Visually rich reflections, calm controlled motion, premium look, no chaos. Continuity anchors: * Location: rainy city intersection, zebra crossing, wet asphalt mirror reflections, neon cyan/magenta, light drifting mist * Lighting: one streetlight + neon spill, deep shadows, soft bloom highlights * Atmosphere: light rain, subtle fog, crisp puddle ripples Camera: Wide shot, low tripod height, perfectly locked (no shake, no pan, no zoom). 35mm feel, medium depth of field, sharp reflections. Action beats (single continuous shot): 0–4s: A gust of wind pushes mist across frame; puddles ripple softly. 4–8s: A cyclist passes once through the zebra crossing, leaving a clean spray trail. 8–12s: In the far background, a car turns; headlights sweep across wet asphalt, reflections flare briefly then settle. End on a stable “hero frame”. Audio: Ambience: distant city hum + light rain. SFX: one clean tire spray + subtle headlight pass-by. Constraints: No logos. No readable text. No subtitles/overlays. Avoid storefront signs and billboards. Negative: no text, no letters, no numbers, no logos, no captions, no subtitles, no watermark, no jitter, no glitch, no shaky cam, no excessive motion blur.

Tips & Limitations

What works best

  • Use camera_fixed for locked-off shots and steadier motion.
  • Reuse a seed for repeatable variations.
  • Add an end frame for smoother I2V resolves and cleaner landings.
  • Keep clips short (4–12s) and actions simple for best coherence.
  • Use audio sparingly: one short line + ambience + 1 key SFX.

Common problems → fast fixes

  • Motion feels messy → enable camera_fixed; reduce action speed; simplify background.
  • Drift across takes → lock a seed; keep the same prompt structure; change one variable.
  • Audio/lip sync drifts → shorten lines; avoid fast head turns; keep the shot calmer.
  • Random text/logos → strengthen negative ("no text, no logos, no UI") and keep signage out of frame.

Hard limits to keep in mind

  • Short-form only (4–12s).
  • 24 fps.
  • Resolution and pricing vary by tier; check the live spec chips before rendering.
  • Still no reliable tiny on-screen text — overlay critical copy in post.

Safety & people / likeness

  • Don’t generate real people or public figures (celebrities, politicians, etc.).
  • No minors, sexual content, hateful content, or graphic violence.
  • Don’t use someone’s likeness without consent.
  • Some prompts and reference images may be blocked — generic characters and scenes are fine.
