Kling 3.0 Motion Control API
Drive any character with a reference motion video — Kling 3.0's motion-controlled generation lets you replay any movement on a new subject without mocap rigs.
About the Kling 3.0 Motion Control API
What Kling 3.0 Motion Control does, how it fits in the Kuaishou model lineup, and why teams reach for it.
Kling 3.0 Motion Control is a video generation model from Kuaishou, available through the WaveSpeedAI REST API. Drive any character with a reference motion video — Kling 3.0's motion-controlled generation lets you replay any movement on a new subject without mocap rigs.
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.
Choreography videos
Upload a dance reference + a character image — get a video of that character performing the same choreography. Useful for music videos, brand content, and creator pipelines.
Sports action with custom subjects
Drive any character with sports motion references — useful for brand mascot animations, athlete-themed promos, and educational sport content.
Character swap in existing motion
Replace the subject of an existing video with a new character while keeping the original motion. Useful for stunt-double-style workflows and creative re-castings.
Animated character reels
Single character image + a library of motion reference clips → a full animation reel showcasing the character in different actions.
Indie-creator mocap alternative
For solo creators without access to a mocap studio — record yourself doing the motion, drive a stylized character with it. No suit, no rig, no studio.
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.
Be specific about camera moves
Mention concrete cinematography vocabulary — orbit, dolly-in, push-in, pan-left, crane shot, handheld follow. Generic prompts produce static or arbitrary camera choices; named camera moves map directly to motion intent in the model's training data and dramatically improve shot quality.
Anchor character identity with reference images
If your prompt depends on a specific person, character, or product, upload a reference image alongside the prompt. Without a reference, identity drifts across frames and across shots — the same character ends up looking like a slightly different person each generation.
Describe lighting and time of day
Lighting cues like 'golden hour, soft warm directional light' or 'overcast diffused light, slate-grey sky' improve quality and consistency far more than vague quality modifiers. Lighting is one of the strongest priors the model conditions on.
Use negative prompts to suppress common failure modes
Useful negatives for video: 'frame flicker, motion blur, watermark, text artifacts, distorted hands, low resolution, jpeg compression'. Negative prompts cost nothing and noticeably reduce the rate of generations you'd otherwise re-roll.
Pick the shortest duration that captures your beat
Most prompts work best at 5-8 seconds. Longer clips amplify temporal inconsistencies (subject morphing, environment drift). If you need a 20-second sequence, generate three 6-8 second clips and edit them together — quality stays higher than one long generation.
Match aspect ratio to platform up front
9:16 for TikTok / Reels / Shorts, 16:9 for landscape feeds and YouTube, 1:1 for post grids. Models train slightly differently per aspect ratio — cropping a 16:9 to 9:16 after the fact loses both fidelity and the composition the model intended.
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 are pose-driven animation endpoints. Wan 2.2 Animate is open-weight-derived and supports LoRA fine-tuning. Kling Motion Control has stronger identity preservation and motion priors trained on Kuaishou's massive video catalog.
Kling 3.0 Motion Control vs Standard Kling 3.0
Standard Kling generates from text or image without explicit motion reference. Motion Control accepts and follows a driving video — the right tool when you need a specific movement, not a generated approximation.
Kling 3.0 Motion Control vs Runway ML motion tools
Runway's motion tools require multi-step workflows in their editor. Kling Motion Control is a single REST call — simpler to integrate into your own pipeline.
