It preserves facial consistency, body alignment, and visual clarity across frames. SteadyDancer is a first-frame-preserving image-to-video animation framework built on the Wan 2.1 I2V model, enhancing it with pose-driven motion modeling to generate stable, identity-consistent character videos. You'll gain refined control over pose and rhythm without losing character identity. Perfect for dance, portrait, or character motion projects. Create high-fidelity, natural movement animations efficiently using next-gen I2V modeling.</p><p><strong>Important nodes:</strong></p><h2 id="key-nodes-in-comfyui-steadydancer-workflow">Key nodes in Comfyui SteadyDancer workflow</h2><h3 id="wanvideoaddsteadydancerembeds-(71)"><code>WanVideoAddSteadyDancerEmbeds</code> (#71)</h3><p>This node is the SteadyDancer heart of the graph. It fuses the image conditioning with pose latents and CLIP‑vision cues so the first frame locks identity while motion unfolds naturally. Adjust <code>pose_strength_spatial</code> to control how tightly limbs follow the detected skeleton and <code>pose_strength_temporal</code> to regulate motion smoothness over time. Use <code>start_percent</code> and <code>end_percent</code> to limit where pose control applies within the sequence for more natural intros and outros.</p><h3 id="poseandfacedetection-(89)"><code>PoseAndFaceDetection</code> (#89)</h3><p>Runs YOLOv10 detection and ViTPose‑H keypoint estimation on the driving video. If poses miss small limbs or faces, increase input resolution upstream or choose footage with fewer occlusions and cleaner lighting. When multiple people are present, keep the target subject largest in frame so the detector and pose head remain stable.</p><h3 id="vhs_loadvideo-(75)"><code>VHS_LoadVideo</code> (#75)</h3><p>Controls what portion of the motion source you use. Increase the frame cap for longer outputs or lower it to prototype rapidly. The <code>force_rate</code> input aligns pose spacing with the generation rate and can help reduce stutter when the original clip’s FPS is unusual.</p><h3 id="layerutility:-imagescalebyaspectratio-v2-(146)"><code>LayerUtility: ImageScaleByAspectRatio V2</code> (#146)</h3><p>Keeps frames within a chosen long‑side limit while maintaining aspect ratio and bucketing to a divisible size. Match the scale here to the generation canvas so SteadyDancer does not need to upsample or crop aggressively. If you see soft results or edge artifacts, bring the long side closer to the model’s native training scale for a cleaner decode.</p><h3 id="wanvideosamplersettings-(119)"><code>WanVideoSamplerSettings</code> (#119)</h3><p>Defines the denoising plan for the Wan 2.1 sampler. The <code>scheduler</code> and <code>steps</code> set overall quality versus speed, while <code>cfg</code> balances adherence to the image plus prompt against diversity. <code>seed</code> locks reproducibility, and <code>denoise_strength</code> can be lowered when you want to hew even closer to the reference image’s appearance.</p><p>…</p><h3 id="notes">Notes</h3><p><strong>SteadyDancer in ComfyUI | I2V Human Animation Workflow</strong> — see <a target="_blank" rel="ugc" href="https://www.runcomfy.com/comfyui-workflows/steadydancer-in-comfyui-i2v-human-animation-workflow?utm_source=civitai&amp;utm_medium=referral">RunComfy page</a> for the latest node requirements.</p>
