Capabilities

What it does best.

Seedance capabilities

Resolution

  • Three output tiers: 480p (faster generation), 720p (quality-cost balance), and 1080p (highest quality)[^1]

Aspect ratios

  • Six supported ratios: 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16. Covers ultra-wide film, landscape, square, portrait, and vertical social[^1]

Duration and frame control

  • Clip length is configurable from 2 to 12 seconds in 1-second increments[^1]
  • Override duration at the frame level with num_frames for precise control[^2]

Conditioning and reproducibility

  • Text prompt drives generation. Supply a seed integer for fully reproducible outputs[^2]
  • Camera-fixed mode locks the camera position for stable, controlled scenes[^2]

Safety

  • Built-in safety checker is enabled by default. Toggle it off via API parameter when needed[^2]

Delivery and integrations

  • Async queue system with webhook support handles long-running jobs without blocking[^2]
  • Input files accepted as publicly hosted URLs or Base64 data URIs[^2]
  • Native SDKs for JavaScript/Node.js and Python via the @fal-ai/client library[^2]

FAQ

Seedance 1.5 / 2.0 FAQs

How much does Seedance cost on Coinis?

Seedance 1.5 Pro (720p) runs at $0.06/sec on Coinis. Seedance 2.0 Fast (WaveSpeed route) runs at $0.17/sec. Seedance 1.0 Pro via BytePlus is priced at $0.794 per 5-second 720p clip. Dreamina Seedance 2.0 Fast is priced at $0.938 per clip. All routes are available under one Coinis account with no separate vendor contracts.

What is the difference between Seedance 1.5 Pro, 2.0 Fast, and 1.0 Pro?

Seedance 1.5 Pro at 720p is the cost-efficient route, best for high-volume production at $0.06/sec. Seedance 2.0 Fast via WaveSpeed prioritizes inference speed at $0.17/sec and is the go-to for rapid turnaround. Seedance 1.0 Pro via BytePlus delivers up to 1080p output and is billed per clip, making it ideal when maximum quality matters more than per-second cost. Dreamina Seedance 2.0 Fast covers longer 15-second UGC clips at $0.938 per clip.

Is there a Seedance API I can call directly?

Yes. POST to https://api.app.coinis.com/v1/video/generate with your variant ID, prompt, resolution, aspect ratio, duration, and optional seed. The API uses an async queue system with webhook support. Full schema and code samples for JavaScript and Python are on the Seedance API sub-page.

Can I use Seedance-generated videos commercially?

Yes. Commercial use is explicitly permitted across all Seedance routes available on Coinis. This applies to ad creative, branded content, product demos, and UGC. No additional licensing agreements are required through the Coinis platform.

What resolutions, aspect ratios, and clip lengths does Seedance support?

Seedance supports three resolution tiers: 480p, 720p, and 1080p. Six aspect ratios are available: 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16. Clip duration is configurable from 2 to 12 seconds in 1-second increments. Frame-level control is also available via the num_frames parameter.

How do I reproduce a Seedance generation?

Pass a fixed seed integer in your API request to lock the generation to a specific output. Use -1 for a random seed when you want variety. Enable camera-fixed mode to lock the camera position across retries. These two parameters together give you consistent, repeatable results for product shots and templated content.

Why is Seedance 2.0 routed through WaveSpeed instead of Volcengine direct?

Seedance 2.0 on Volcengine direct is currently restricted to enterprise partners and is not publicly available via the standard API. The WaveSpeed route provides the same Seedance 2.0 Fast inference at $0.17/sec without requiring a separate enterprise agreement. Coinis will update routing as Seedance 2.0 reaches general availability on Volcengine.
