Introduction to Steady Dancer Animation Generator
Steady Dancer is a 14-billion-parameter human image animation model that advances video generation through a unique video-to-video framework. It transforms static reference images into motion by learning posture and rhythm from a driving video while keeping identity and appearance consistent from the very first frame. With its robust first-frame preservation, temporal coherence, Condition-Reconciliation Mechanism, and Synergistic Pose Modulation Modules, Steady Dancer bridges creative animation and scientific precision for reliable, lifelike output that maintains motion fidelity without losing character integrity.
Steady Dancer video-to-video lets you turn a still reference image into a seamlessly animated clip that dances, moves, and performs naturally. Built for creators, marketers, and virtual idol designers, its generation tool delivers polished motion transfer videos that preserve the look and feel of your subject while adapting smoothly to any performance style.

Model overview
- Task: video-to-video
- Resolution/Specs: Up to 720p output; duration follows the input driving video; deterministic seeds for reproducibility
- Key strengths: 1) Strong identity preservation from a single reference image 2) High temporal consistency with minimal flicker 3) Faithful pose and motion following from the driving video 4) Simple browser and API integration for rapid prototyping
Steady Dancer transforms a single image into realistic, identity-preserving motion aligned to a driving video, producing smooth video-to-video results. It builds on diffusion-based motion transfer techniques with temporal attention and pose/motion conditioning to deliver lifelike dance and movement generation.

Input parameters
Below are the inputs supported by Steady Dancer. Provide a clear reference image and a stable, well-framed driving video for best results.
Core inputs
| Parameter | Type | Default/Range | Description |
|---|---|---|---|
| image | string (image URI) | "" | Reference image for identity. Use a clear, well-lit portrait or full-body image depending on your use case. Provide an accessible URI (e.g., https URLs). |
| video | string (video URI) | "" | Driving video that defines motion and timing (e.g., a dance clip). Use stable framing, minimal occlusion, and typical 24–30 fps footage. Provide an accessible URI. |
| prompt | string | "" | Optional text to guide style and appearance (e.g., outfit, lighting, background). Motion is sourced from the driving video; keep the prompt focused on look and tone. |
Generation settings
| Parameter | Type | Default/Range | Description |
|---|---|---|---|
| resolution | string (enum) | 480p (choices: 480p, 720p) | Output resolution. Use 480p for faster previews and 720p for higher fidelity final renders. |
| seed | integer | -1 to 2147483647 (default: -1) | Random seed. Set to a fixed value for reproducibility; -1 selects a random seed each run. |
Recommended settings
- For fastest iteration with Steady Dancer, start at 480p, verify identity and motion fidelity, then switch to 720p for final export.
- Use a high-quality, front-facing reference image with consistent lighting; avoid heavy occlusions, sunglasses, or extreme angles for better identity preservation.
- Choose a driving video with stable framing, moderate motion, and minimal motion blur. Center the subject and avoid rapid cuts for best temporal consistency.
- Keep the prompt concise and descriptive for styling only (outfit, color palette, background). Let the driving video determine poses and timing.
- When reproducibility matters, set a fixed seed; when exploring variations, set seed to -1 to randomize.
Output quality and performance
- Output format: MP4 video at the selected resolution; duration follows the driving video. Audio is typically not included.
- On RunComfy’s cloud GPUs, Steady Dancer provides low-latency, production-ready inference with no cold starts. Runtime scales with video length and resolution (480p for speed; 720p for quality), and concurrent requests are handled by the managed infrastructure.
Recommended use cases
- Social content and short-form video: Turn a static portrait into engaging dance or movement clips with Steady Dancer.
- Virtual try-on and fashion demos: Preserve identity while showcasing outfits and styles with natural motion.
- Character and avatar animation: Drive stylized or semi-realistic characters from reference images using real motion.
- Marketing and creative production: Rapidly prototype motion-led visuals while maintaining brand identity.

Frequently Asked Questions
What is Steady Dancer and what does its video-to-video capability do?
Steady Dancer is a human image animation model that uses a video-to-video process to transform a reference image and a motion-driving clip into a realistic animated video. It preserves the identity of the person from the image while replicating motions from the driving video.
How does the Steady Dancer video-to-video model differ from traditional motion transfer tools?
Unlike many other motion transfer systems, Steady Dancer uses advanced modules to reconcile appearance with motion in its video-to-video generation. This results in smoother animation, reduced identity drift, and better alignment even when the reference and driving sources differ structurally.
Is Steady Dancer free to use or does it have a credit-based pricing model?
Access to Steady Dancer currently requires user login on the Runcomfy platform. It operates on a credit-based system, with new users receiving free trial credits. Once the free credits are used, additional credits can be purchased to continue using Steady Dancer’s video-to-video service.
What kind of inputs and outputs does Steady Dancer support for video-to-video generation?
Steady Dancer accepts a static reference image and a driving video as inputs. The output is an animated video where the character mimics the poses and movements from the driving clip. The model supports various resolutions, such as 480p for previews and 720p for higher-quality outputs.
Who can benefit most from using Steady Dancer’s video-to-video technology?
Steady Dancer’s video-to-video system is ideal for creators in social media, entertainment, VTuber production, cosplay previews, and content marketing. It’s also valuable for researchers studying motion synthesis or virtual avatar animation.
What are the main advantages of using Steady Dancer compared to older motion generation models?
Steady Dancer offers strong first-frame preservation, temporal coherence, and identity stability across frames in its video-to-video outputs. Compared with earlier models, it minimizes flickering and misalignment, producing smoother and more consistent animations.
What limitations should users be aware of when using Steady Dancer for video-to-video animation?
Steady Dancer performs best with compatible reference images and driving videos that share similar body framing and angles. Performance may degrade with very fast or occluded motions, and it’s optimized for short to medium-length clips rather than extended sequences.
Can Steady Dancer be used on mobile devices for quick video-to-video creation?
Yes, Steady Dancer is accessible through the Runcomfy web platform, which is optimized for desktop and mobile browsers. Users can create video-to-video animations conveniently without requiring any specialized hardware setup.
Does Steady Dancer offer an API for developers integrating its video-to-video generation into other apps?
Yes, Steady Dancer provides a RESTful API that allows developers to integrate its video-to-video animation features into third-party platforms or custom workflows, enabling automated content generation or creative app experiences.
