SEEDANCE 1.0 PRO

Seedance 1.0 Pro is a professional image-to-video generation model, developed by Bytedance, designed to animate static images into natural-looking, dynamic video clips. The model utilizes advanced AI motion synthesis to create smooth, realistic movements while preserving high visual fidelity and temporal consistency throughout the output sequence. Seedance is targeted at users seeking to enhance creative projects, marketing materials, and social media content by transforming static visuals into engaging motion content.

Key Capabilities

Seedance 1.0 Pro is engineered to generate fluid, realistic motion from a single input image, maintaining the original image's quality and coherence across frames. The model is capable of understanding complex scenes, creating movement that obeys physical plausibility and honors the spatial relationships between objects. Example use cases specifically include:

• Portrait photos where facial expressions and subtle movements are animated naturally.
• Landscape scenes brought to life with dynamic elements such as flowing water, swaying trees, or changing skies.
• Product shots enhanced with smooth rotations or dramatic camera transitions.
• Abstract artwork animated with creative motion effects.

Input and Output Modalities

The model accepts both image and text as input modalities: users provide a single image (supported formats include jpg, jpeg, png, webp, gif, avif) and a text prompt describing the desired motion or scene details. Output is in MP4 video format, with the additional option of receiving result metadata in JSON.

Technical Details and Configurations

Seedance 1.0 Pro supports a range of customizable parameters for granular control over video generation:

• Aspect Ratio: Choose from standard presets such as 21:9, 16:9, 4:3, 1:1, 3:4, 9:16, or auto.
• Resolution: Select from 480p (for fast generation), 720p (balanced), or 1080p (highest quality, available in the Pro model).
• Duration: Specify the video length in seconds, with options ranging from 2 to 12 seconds (default is 5 seconds).
• Camera Fixed: Option to fix or move the virtual camera during animation.
• Seed: Set a specific random seed for reproducibility or allow random generation.
• Safety Checker: Can be enabled or disabled; enabled by default for safety compliance.
• End Image URL: Optionally provide a second image for the video to resolve into (defaults to none).

Performance and Quality

Seedance is designed for high-quality video generation, supporting output resolutions up to 1080p in the Pro model and 720p in Lite mode, both typically generating five-second video clips. The model ensures smooth, physically plausible motion and visual stability, making it suitable for scenarios demanding professional visual fidelity. Processing time varies with input complexity and system queue.

Integration and Support

Users can easily get started by installing the official client libraries (available for JavaScript, Python, Swift, Java, Kotlin, and Dart/Flutter) and configuring API credentials. The model is available via API and playground interfaces. Comprehensive documentation, code examples, and sample applications are provided for streamlined integration into production or creative workflows.

Best Practices

For best results, it is recommended to use high-quality source images with clear subjects and good lighting. Consider the intended motion while composing the input image and adjust parameters incrementally to achieve the desired animation effect. Testing various configurations helps optimize output for different content types and use cases.

Limitations and Considerations

Only topics covered in the documentation are included: the model generates video content based on single images and supporting text prompts, with customization options for output duration, resolution, and aspect ratio. Best results are achieved with high-quality input. Output video length and quality are controlled by model settings. The model supports a defined range of video durations and standard output formats (MP4). Further technical or operational limitations are not explicitly documented.

Seedance 1.0 Pro empowers creators and professionals to transform static visuals into high-impact motion content efficiently, while offering detailed control and maintaining a robust support ecosystem for development and deployment.
