Kling Motion Control API
Generate motion-controlled video with reference image + reference video — billed per reference-video second.
Access Kling v3 motion control through APIMaster with model id kling-v3-motion-control. Upload a subject reference image and a motion reference video; choose image or video character orientation and std/pro quality. Billing follows the probed reference video duration.

Upload a reference video or paste its URL to estimate cost.
Estimated cost = reference video billing duration × price per reference video second
Used only for estimation/pre-deduction. Final settlement uses the actual reference-video duration detected by the server and upstream billing data; a shorter output does not reduce the billable duration.
Estimate at the lowest active public route price. Your account group and routed channel may change the effective price; check your billing log for the final charge.

Capabilities
Reference-driven motion
Lock identity from the image and transfer motion from the reference clip.
std / pro modes
Balance speed and quality — pro for higher fidelity output.
Reference-video billing
Pay for server-detected reference video seconds × the effective mode rate. Shorter output does not reduce the charge.

}'Kling Motion Control API — Câu hỏi thường gặp
Which model id do I use?
Always kling-v3-motion-control in the model field.
What inputs are required?
image_url and video_url (public URLs). prompt is optional.
How is duration billed?
The server detects the motion reference duration in video_url. Estimated cost = billable reference seconds × effective per-second rate. A shorter output does not reduce the charge. See live route pricing; account/group rates may differ.
Why was I charged for 29 seconds if the output was only 3 seconds?
Motion Control processes the reference video. Complex or fast motion can produce a shorter result; consumed credits are not refunded or recalculated from the shorter output. At an example effective STD rate of $0.10288 per reference video second, 29 × $0.10288 = $2.98352, even for a 3-second output.
Does duration control the output or cap my charge?
No. duration is optional and used only for estimation/pre-deduction. The server detects the actual reference-video duration and reconciles with upstream billing data. The playground detects video metadata automatically where supported.
Which endpoint?
POST /v1/videos/generations with JSON body — see Quick start and docs.
Is my data safe?
Yes. Requests are encrypted and not used for training.
