Provide a URL to the image for relighting. Use S3 URLs for consistent results.
Set video length in seconds. Opt for 5 seconds for quick previews, 10 for detailed scenes.
Allowed values:
Detail the animation scene vividly. E.g., A sunset beach scene with waves lapping, people playing, sky turning orange.
Choose video clarity; 720p for most uses, 480p for faster processing.
Allowed values:
Define a seed for consistent outputs. Any number 1-999999 suffices.
min : 1,
max : 999999
Whether to fix the camera position.
Defines the width to height ratio of the video. Use 16:9 for landscapes or 9:16 for vertical videos.
Allowed values:
To keep track of your credit usage, you can inspect the response headers of each API call. The x-remaining-credits property will indicate the number of remaining credits in your account. Ensure you monitor this value to avoid any disruptions in your API usage.

Everything you need to know to get the most out of Seedance 1.0 Pro
Seedance PRO Usage Guide
Seedance - PRO is a text-to-video engine that transforms your prompts and reference images into coherent multi-shot videos at up to 720p. Follow this comprehensive guide to tune parameters, optimize quality, and match your workflow—whether you need a quick preview or a polished cinematic cutscene.
Core Inputs
Understanding the essential parameters will help you get started quickly:
- •prompt (required): A vivid description of scene, action, style and camera moves
- •image_url (required): S3 link to your reference or relighting image
- •duration (required): Choose between 5s or 10s
- •resolution (advanced): 480p for speed or 720p for detail
- •seed (advanced, optional): Integer (1–999,999) to reproduce consistent results
Prompting Best Practices
Master these techniques to create compelling videos:
1. Be Specific
Break down your vision into clear components:
- •Setting: "Sunset beach with rolling waves"
- •Action: "Surfers riding close to camera"
- •Camera: "Wide-to-close pan over the shoreline"
2. Style & Lighting
Set the mood with descriptive language:
- •"Photorealistic dawn mist"
- •"Cyberpunk neon reflections on wet asphalt"
3. Multi-Shot Sequencing
Guide camera movement with professional terminology:
- •Use "dolly in," "track left," "cut to close-up"
4. Duration Choice
Select the right timeframe for your needs:
- •5 seconds: Fast A/B tests, thumbnails, previews
- •10 seconds: Narrative beats, longer camera moves, stable storytelling
5. Consistency Across Runs
Maintain visual coherence by using the same seed for multiple variants or shots.
Parameter Presets by Use Case
Choose the optimal settings for your specific workflow:
| Use Case | Duration | Resolution | Seed | Prompt Style |
|---|---|---|---|---|
| Quick Preview | 5s | 480p | (none) | "Midday forest clearing, static cam" |
| Social Media Teaser | 5s | 720p | 42 | "Close-up product spin, soft lighting" |
| Storyboard & Prototyping | 10s | 480p | 2023 | "Two characters talk, over-shoulder cut" |
| Game Cinematic Sequence | 10s | 720p | 999999 | "Epic battle, wide shot → tight focus" |
| Mood-Board Concept Art | 10s | 720p | 12345 | "Neo-Tokyo alley, rain, neon signs" |
Tips to Maximize Quality
Fine-tune your approach with these professional insights:
- •Shorter resolutions reduce rendering time but sacrifice detail
- •Higher seeds produce subtle variations; lower seeds create bolder differences
- •Iterate quickly: Lock your prompt structure and change only one variable per test
- •Combine styles: Mix photorealism with stylized color grading for unique visual flair
Pro Tip: By following these guidelines and parameter presets, you'll achieve stable frames, accurate prompt fidelity, and cinematic polish with Seedance PRO—whether creating a rapid storyboard or a full 10-second hero sequence.
