Kling 3.0 Motion Control API
Kuaishou Kling 3.0 Motion Control — transfers motion from a reference video to animate a still character image. Upload a character image plus a motion clip (dance, action, gesture); the model extracts the movement to generate smooth, realistic video. Standard and Pro tiers.
Standard and Pro tiers, with pricing scaled to the reference video's duration (3-30 seconds). Pair a character image with a motion reference; output is smooth, realistic video of the character performing the referenced motion.

The Kling 3.0 Motion Control family on WaveSpeedAI ships 1 REST endpoint covering Motion-Control workflow. Each variant carries its own pricing, parameter knobs, and example outputs — pick the one that matches your input modality and production constraints, or call several from the same API key to compose multi-step pipelines.
Run Kling 3.0 Motion Control through the same API key, billing account, and rate-limit envelope you use for the other 1,000+ AI models on WaveSpeedAI. No separate vendor setup, no per-provider SDKs, no per-vendor rate-limit envelopes — one integration covers everything from text-to-image and text-to-video through audio synthesis, 3D generation, upscaling, and editing.

How to use the Kling 3.0 Motion Control API
Four steps from signup to a finished generation. Full Python, Node.js, and cURL examples are in the API section below.
- 1
Get an API key
Sign up for a WaveSpeedAI account and copy your API key from the dashboard. New accounts come with free starter credits — enough to run the playground a few dozen times before billing kicks in.
- 2
Submit a prediction
POST your input as JSON to https://api.wavespeed.ai/api/v3/kwaivgi/kling-v3.0-std/motion-control. The endpoint returns a prediction id immediately — generations are async so you don't hold an open connection during inference.
- 3
Poll for completion
GET https://api.wavespeed.ai/api/v3/predictions/{request_id}/result every 1-2 seconds. The response includes a status field; keep polling until it flips from"queued" or"processing" to"completed".
- 4
Read the output URL
Once status is"completed", read the URL from data.outputs[0]. The URL points to your generated media on the WaveSpeedAI CDN — image, video, audio, or 3D file depending on the Kling 3.0 Motion Control variant you called.
What you can build with Kling 3.0 Motion Control
Common workflows developers and creators use the Kling 3.0 Motion Control API for.
Dance and choreography videos
Catalog example: "dance." Pair a character image with a dance reference clip; the model transfers the choreography to the character. Useful for music videos, social content, and brand-character animations.
Action and gesture transfer
Catalog examples:"action, gesture." Drive any character with sports motion, expressive gestures, or stunt-style action from a reference video.
Character swap in existing motion
Use a reference video as the motion source and a different character image as the subject. Effectively a character-swap workflow on the motion of an existing clip.
Mocap-alternative for indie creators
Single character image + a phone-recorded motion reference replaces studio mocap for many use cases — particularly content where the motion is the headline and rig-quality isn't critical.
Std vs Pro tier choice
Standard tier for default; Pro tier for top-tier output. The Pro motion-control endpoint pairs with the standard Pro pricing in the Kling family.
Tips for prompting Kling 3.0 Motion Control
Practical advice for getting better outputs from Kling 3.0 Motion Control — drawn from the patterns that work across video models in production pipelines.
Isolate the motion in your reference clip
Fewer subjects in the reference clip = cleaner motion transfer to the target character. If your reference video has multiple people moving, crop or re-record so the motion source is unambiguous.
Match the target character pose to the reference start
If the reference starts with a standing pose, supply a standing character image. Closer match between starting poses = smoother handoff and fewer first-frame artifacts.
Vertical aspect ratios for choreography content
Most use cases are dance / sports / TikTok-style — generate at 9:16 to match delivery platforms. The model trains well on vertical and avoids the post-crop quality loss.
Use as a mocap-rig alternative
A single character image + a phone-recorded motion clip replaces studio mocap for many use cases — stunt content, dance reels, character-driven brand work — significantly faster and cheaper than producing the motion conventionally.
Combine with standard Kling for context shots
Generate the establishing shot or scene context with standard Kling 3.0 (text-to-video), then motion-control the action sequence. Editing these together produces longer narrative-coherent pieces than either tool alone.
Kling 3.0 Motion Control API pricing
Pricing is per-output. The final charge scales with the parameters you set in each variant's playground (resolution, duration, output count, references).
| Endpoint | Type | Starting price |
|---|---|---|
| kwaivgi/kling-v3.0-std/motion-control | motion-control | $0.63 |

When to pick Kling 3.0 Motion Control over similar models on WaveSpeedAI.
Kling 3.0 Motion Control vs Wan 2.2 Animate
Both transfer pose/motion to animate a character. Wan 2.2 Animate produces up to 120s 720p clips and is open-weight-derived. Kling Motion Control is constrained to the reference video duration (3-30s) but is built on Kuaishou's video corpus for motion priors.
Kling 3.0 Motion Control vs Standard Kling 3.0
Standard Kling 3.0 (text-to-video / image-to-video) generates from text or image WITHOUT an explicit motion reference. Motion Control accepts and follows a driving video — the right pick when a specific movement is required, not a generated approximation.
Kling 3.0 Motion Control vs Wan 2.2 Fun-Control
Wan 2.2 Fun-Control uses Control Codes (preset motion templates) and is Apache 2.0 licensed for commercial use. Kling Motion Control accepts arbitrary motion reference videos rather than preset codes — different control mechanism, different licensing terms.
