Kling V2.6 Motion Control API Limits: Resolution, Inputs and Request Boundaries

APIMART serves Kling V2.6 Motion Control through POST /v1/videos/generations. The current documentation describes an asynchronous submit-and-poll workflow. The boundaries below were checked on September 2, 2026.

Verified boundaries

• Both image_url and video_url are required; prompt is optional.
• character_orientation=image accepts a reference video from 3 to 10 seconds.
• character_orientation=video accepts a reference video from 3 to 30 seconds.
• mode is required and supports std or pro.
• The endpoint can preserve original sound and accepts optional watermark configuration.
• Processing is asynchronous, returns task_id and bills the server-detected reference-video duration.

Minimal integration rule

Send the documented model ID, required prompt and only compatible optional inputs. Persist the returned task_id, implement bounded polling and backoff, and keep 400, 401, 402, 429 and 5xx responses out of completed-output metrics.

FAQ

Which endpoint serves Kling V2.6 Motion Control?

Use POST /v1/videos/generations with the documented model ID and Bearer authentication.

Is processing synchronous?

No. A successful submission returns a task ID that must be polled for completion.

What is the first production safeguard?

Validate model ID, quantity or duration, resolution and input combinations before submission.

Can documented limits change?

Yes. Treat the live endpoint documentation as the source of truth and version your request profile.

Should a submitted task be counted as completed output?

No. Count success only after the task endpoint reports a completed result.
