What can you build with the Motion Control API?

Avatar and character animation from reference video

Animate a still character image from a reference performance video without manual rigging or frame-by-frame editing. This workflow is useful for creator tools, virtual avatars, short-form content, and character-driven video production where natural human motion matters.

Start creating
Avatar animation from reference video

Dance, gesture, and performance transfer for social content

Transfer dance moves, gestures, and body performance from one clip to a different character for social media production, marketing assets, and creator workflows. Teams can turn a single motion source into multiple character-led outputs for faster iteration across campaigns.

Reference-driven motion workflows with orientation control

Control whether the generated character follows the direction of the source image or the reference video, then choose 720p or 1080p output based on budget and production needs. This gives developers a more structured motion-control pipeline than generic image-to-video generation.

Why teams choose Motion Control

Kling 3.0 Motion Control gives teams a more controllable way to turn real performance footage into character animation, with predictable per-second pricing and a production-ready API workflow.

More controllable than generic video generation

Instead of asking a model to invent motion from scratch, Motion Control uses a reference performance video as the motion source. That makes output behavior easier to steer for character-driven workflows.

Faster production without manual rigging

Teams can turn a still image plus a motion clip into usable animated output without building a traditional animation pipeline. This reduces setup friction for prototypes, campaign assets, and creator tools.

Predictable API pricing for repeated workflows

Per-second billing, 720p and 1080p modes, and explicit duration limits make it easier to estimate cost before production. That matters for batch jobs, user-generated workflows, and automated content pipelines.

How to integrate the Motion Control API

From reference inputs to delivered animation in three practical steps.

1

Prepare a clean character image and motion source video

Upload a reference image for the target character and a reference video containing the performance you want to transfer. Clear body visibility and stable source motion improve output consistency.

2

Submit an async generation request with motion settings

Send the image, video, quality mode, and orientation parameters to the API. The task runs asynchronously, which makes it easier to integrate into production pipelines, queue systems, and automated workflows.

3

Poll task status, review output, and iterate

Check task status until the result is ready, then review the generated clip and refine inputs when needed. This iteration loop works well for creator products, internal tools, and repeatable video workflows.

Core capabilities of the Motion Control API

Reference-driven character animation with production-oriented controls

Motion

Reference video motion transfer

Use a source performance video to drive movement in a target character image, making motion output more repeatable and easier to control than prompt-only generation.

Orientation

Character orientation control

Choose whether the output character follows the facing direction of the reference image or the source video, depending on the type of motion transfer you need.

Consistency

Subject element consistency support

Combine Motion Control with Kling Custom Element workflows when you need more stable character identity across repeated generations and production variations.

Audio

Original sound preservation

Keep the original sound from the reference video when the workflow calls for motion plus source-audio continuity in the final output.

Pricing

Per-second pricing with explicit output limits

Estimate cost more easily with per-second billing, visible duration constraints, and clear quality tiers. This helps teams plan usage for creator tools and automated pipelines.

Quality

720p and 1080p delivery modes

Choose a lower-cost or higher-quality output path based on production goals, turnaround needs, and budget sensitivity.

Frequently Asked Questions

Everything you need to know about the product and billing.

The Motion Control API transfers human motion from a reference video onto a character in a reference image. It uses Kling's 3.0 model to synthesize natural-looking animation. Both the reference image and reference video are required inputs.
You need a reference image (the character to animate) and a reference video (the motion source). The character should have clear upper body or full body visible. The video should contain clear human motion without cuts or camera movement.
Maximum duration depends on character_orientation: up to 10 seconds when set to 'image' (character faces like the image), or up to 30 seconds when set to 'video' (character faces like the video). Minimum is 3 seconds. Actual duration depends on extractable motion from the reference video.
Motion Control uses per-second billing at 8.1648 credits/second base rate (720p). 1080p quality is 1.333x the base rate. Billed by actual generated duration, rounded up to the nearest second. Check your EvoLink dashboard for your group's specific pricing.
This parameter controls the facing direction of the generated character. Set to 'image' for the character to face the same direction as in the reference image (max 10s video). Set to 'video' for the character to face the same direction as in the reference video (max 30s video).
Yes, you can reference subject elements created via Kling Custom Element using element_list. When using elements, character orientation is currently limited to video orientation only. Maximum 1 element is supported.
Limits, pricing, and available modes are determined by your provider and region. Use your EvoLink dashboard and API responses as the source of truth. Check the API documentation for the most current constraints and parameters.
