How much does the Kling Motion Control API cost?

Pricing is per second × mode (std or pro). The billable second count is the source video's server-probed duration, not a client estimate. See current per-second rates for both tiers in the pricing table on this page; failed jobs refund automatically.

What is the difference between kling-v3-motion-control and kling-v2-6-motion-control?

Both Kling Motion Control tiers share the exact same request shape and parameters. Kling v3 is the latest tier with higher motion fidelity and subject consistency; Kling v2.6 is the budget tier at a lower per-second rate. Switch by changing the model string.

What does character_orientation do?

In Kling Motion Control, character_orientation controls whether the subject's facing follows the reference image (character_orientation = image, reference video 3 to 10s) or the reference video (character_orientation = video, reference video 3 to 30s).

What is the difference between std and pro mode?

In Kling Motion Control, std balances speed and quality; pro renders higher quality and usually takes longer. Both tiers (v3 and v2.6) support both modes, and mode affects the per-second rate — see the pricing table on this page.

What clip lengths does the Kling Motion Control API support?

Kling Motion Control output tracks the reference video's length. With character_orientation = image the source video must be 3 to 10 seconds; with character_orientation = video it can be 3 to 30 seconds. Billing uses the probed source length.

Where is the full Kling Motion Control API reference?

The full parameter list, error codes, and runnable cURL examples live at /docs/kling-motion-control.

Is Kling Motion Control API free or paid?

Paid. Completed generations are charged at the rates in this page's pricing table. Eligible new accounts may receive promotional test credits; availability and amount are shown at signup or in the dashboard. Technical or provider failures are refunded automatically, except where this page documents a charged output-moderation block.

Does Kling Motion Control API require a monthly subscription?

No. Pricing is pay-as-you-go: $1 buys 1,000 credits and credits never expire. Cost scales with what you generate rather than with a recurring fee.

How do I get a Kling Motion Control API key?

Sign up and create a key in the dashboard, no card required. Pass it as a Bearer token in the Authorization header.

Kling Motion Control API — Reference-Driven Motion Transfer

What is the Kling Motion Control API?

Kling Motion Control is Kuaishou's motion-transfer video model: you supply one reference image for the subject and one reference video for the movement, and it maps that movement onto your subject. reAPI serves both version tiers — kling-v3-motion-control and kling-v2-6-motion-control — on one async endpoint, each in std or pro quality, with a character-orientation switch that decides whether the framing follows the image or the video. Billing is per second of the source video's measured length.

What you can build with this model

Real-world workflows and production use cases you can build and ship with this model.

Bring a still subject to life with a reference clip

Upload a subject image and a short motion video. The Kling Motion Control API maps the reference motion onto your subject and returns a clip that keeps the original identity while adopting the movement, rhythm, and timing of the reference.

Generate a clip

Reuse one performance across many subjects

Record a single reference performance once, then swap the reference image to apply the same choreography to different characters. Consistent motion, different subjects — useful for avatars, mascots, and recurring social formats.

Match the take to your shot direction

Pick image orientation to anchor the facing to your reference photo, or video orientation to follow the reference clip and allow up to 30 seconds. Set keep_original_sound to carry the reference soundtrack into the output.

Why reAPI

Reference image plus reference video

The Kling Motion Control API reads the subject from a reference image and the motion from a reference video, so the output keeps identity while adopting the reference movement. No keyframes, no rigging.

Two tiers, one request shape

Kling Motion Control ships two tiers: Kling v3 maximizes motion fidelity and subject consistency, while Kling v2.6 is the budget tier with the same parameters. Switch tiers by changing one string — the request body is identical.

Pay for the seconds you use

Kling Motion Control billing is per second of the source video, measured server-side from the actual clip length rather than a client estimate. Pick std or pro to trade cost for quality. Failed jobs refund automatically.

Kling Motion Control vs Runway Act-Two

Both transfer motion from a driving video onto a target subject. Kling Motion Control takes a reference image plus a reference video, supports image or video orientation, and bills per second across two tiers. Here is how the two compare on publicly documented behavior.

Capability

Kling Motion Control on reAPI

Runway Act-Two

Motion source

In Kling Motion Control, a reference video drives the motion; the subject comes from a single reference image.

A driving performance video animates a character image or generated character.

Subject input

One reference image fixes the subject's appearance and identity.

A character image or a generated character reference.

Orientation control

Kling Motion Control's character_orientation picks whether facing follows the reference image or the reference video.

Facing follows the driving performance; no separate orientation switch documented.

Source audio

keep_original_sound retains the reference video's soundtrack in the output.

Audio is tied to the driving performance video.

Clip length

Kling Motion Control runs up to 10s with image orientation or 30s with video orientation, set by the source clip.

Short performance clips; length follows the driving video.

Pricing model

Kling Motion Control bills per second of probed source footage; two tiers trade cost for fidelity, pay-as-you-go credits.

Credit-based pricing tied to plan and resolution.

Comparison reflects publicly documented behavior at the time of writing. Model behavior and pricing can change; check the pricing card above and the API docs for current values.

Frequently asked questions

Common questions about this model.

The Kling Motion Control API is a reference-driven motion-transfer video model. You pass a reference image (the subject) and a reference video (the motion), and Kling Motion Control returns a clip of your subject performing the reference motion. An optional prompt refines camera, motion, and style.
