SUPPORTED SEEDANCE LEGACY PRO ROUTE

Seedance 1.5 Pro

Camera-fixed shots, seeded variants and start/end frame control for supported older Seedance workflows.

Use Seedance 1.5 Pro when you need the older supported Seedance route: repeatable short clips, optional audio, seed control, camera-fixed setups and image-to-video landings. Use Seedance 2.0 for current 2.0 production work.

Camera-fixed renders

See locked-camera shots possible with Seedance 1.5 Pro — supported older Seedance model for short cinematic clips.

Recreate a variant

Open the app with the same seed, ratio and camera setting.

Audio on/off

Keep native audio or switch it off for a lower quote.

Start/end frames

Use a start image and optional end frame in I2V.

Controlled legacy route

Useful for repeatable Seedance 1.5 tests before moving to 2.0.

Use 1.5 Pro or Seedance 2.0?

Use 1.5 Pro for legacy-compatible camera-fixed and seeded tests. Use Seedance 2.0 for the current native-audio production workflow.

Need repeatable variants?

Keep one prompt structure, reuse seed control, then change only the action, timing or audio cue you are testing.

How to Write a Great Seedance 1.5 Pro Prompt

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

Source: Seedance 1.5 Pro API Docs

How to prompt Seedance 1.5 Pro

Text prompt

Write one subject, one action, lighting, style and an optional audio cue.

Camera-fixed setup

Use camera_fixed for locked-off product, city or storyboard shots.

Image-to-video

Start from one image, then add an end frame when the landing pose matters.

Seeded variant

Reuse the same seed to compare small prompt changes without changing the whole look.

Upgrade path

Use Seedance 2.0 when the project needs the current 2.0 workflow.

Quick prompt (fast iteration)

Use 1–2 sentences when you want variations.

[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.

Global principles

  • Prefer camera-fixed shots when you want steadier motion and fewer artifacts.
  • Keep one readable action per clip (or per beat).
  • Use a seed when iterating — change one variable at a time.
  • If audio is on: keep dialogue short and add only 1–2 sound cues.

Engine quirks / what to watch for

  • camera_fixed is a strength: use it for locked camera realism and product shots.
  • Seedance is short-form: keep beats simple and avoid cramming multiple actions.
  • End frame (I2V) helps land transitions; don’t introduce new actions in the last second.
  • Audio is best with minimal cues; long monologues can drift.
  • If text matters, plan to overlay it in post (tiny text is unreliable).

Tips & Limitations

Best practices, common fixes, and important limitations to help you get the strongest results with Seedance 1.5 Pro.

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.

FAQ

What does camera fixed do?

It locks the camera for steadier motion and stronger continuity between frames.

Can I disable audio?

Yes. Audio is on by default but you can toggle it off for lower cost.

How should I use seed control?

Use -1 for random exploration, then reuse a fixed seed when you want to compare small prompt, camera_fixed, timing or audio changes without changing the whole look.

Does Seedance 1.5 Pro support start and end frames?

Yes for image-to-video: use one start image and an optional end frame when the final pose, product position or transition landing matters.

What resolutions are supported?

T2V supports 480p and 720p. I2V supports 480p, 720p, and 1080p.

Is Seedance 1.5 Pro still the main Seedance Pro workflow on MaxVideoAI?

Seedance 1.5 Pro is the supported older Seedance Pro workflow on MaxVideoAI, but Seedance 2.0 is now the main current Seedance model for broader production work.
