model: kling-v2-6-motion, save the returned img_uuid, then poll or use a callback for asynchronous completion.Kling 2.6 Motion Control API for Character-Driven Video
Access Kling 2.6 Motion Control through GoEnhance with one character appearance image and one motion reference video. Submit
Get API Key
Pair appearance with continuous motion
Define the character with one image
Provide a required JPG, JPEG, or PNG through image_url. The file can be up to 50MB, must be at least 300px per side, and needs a 1:2.5 to 2.5:1 aspect ratio with the character's head and upper or full body clearly visible.
Transfer motion from a reference video
Supply a required MP4 or MOV through video_url. Choose whether the output faces like the motion video or appearance image with character_orientation; that setting also determines the 30- or 10-second input limit.
Validate both reference files before submission and omit unsupported duration or 4K fields.
Kling 2.6 Motion Control API capabilities
Exact model ID
POST to <code>https://api.goenhance.ai/api/v1/videos/generations</code> with <code>model</code> set to <code>kling-v2-6-motion</code>.
Required prompt
Describe appearance details or wardrobe in a required prompt of up to 2,500 characters.
Appearance image
Use one required <code>image_url</code>; Kling 2.6 Motion Control does not accept the 3.0 model's element-based appearance input.
Motion video
Use one required MP4 or MOV up to 100MB, with dimensions from 340px to 3,850px and continuous usable motion.
Orientation limits
<code>video</code> is the default and accepts 3–30 seconds. <code>image</code> follows the appearance image's facing and accepts 3–10 seconds.
Resolution and sound
Choose 720p or 1080p; there is no 4K tier. <code>generate_audio</code> can keep the motion video's original soundtrack but does not generate native audio.
Estimate the maximum request cost as measured motion-video seconds multiplied by the exact resolution rate.
Kling 2.6 Motion Control API pricing
720p pricing
3.5 tokens per generated second, equal to $0.07 per second at the documented $0.02-per-token conversion.
1080p pricing
5.6 tokens per generated second, equal to $0.112 per second at the documented $0.02-per-token conversion.
Measured-duration billing
GoEnhance first copies and measures <code>video_url</code>, then charges that measured input duration as an upper bound. Kling bills the generated output length, which may be shorter when motion cannot be continuously extracted.
Integrate motion control in six steps
1
1. Create an API key
Create a GoEnhance API key and send it with your authenticated request.
2
2. Validate the appearance image
Check format, file size, pixel dimensions, aspect ratio, visibility, and unobstructed head and body framing.
3
3. Validate the motion video
Check MP4 or MOV format, the 100MB limit, pixel range, and the 3–30s or 3–10s orientation-specific duration.
4
4. Submit the generation
POST the model ID, prompt,
image_url, video_url, orientation, resolution, and optional callback URL. 5
5. Persist the task ID
Store
data.img_uuid from the accepted response and use it as the durable job identifier. 6
6. Track terminal status
Poll
GET /api/v1/jobs/detail or handle callback updates for processing, success, and failure idempotently.Use only appearance and motion assets you are authorized to process, especially when preserving source audio.
Developer use cases for motion-controlled video
Character performance pipelines
Apply approved motion references to a consistent character image for reviewable short-form video production.
Dance and choreography concepts
Prototype movement-led clips from licensed or original motion footage while preserving application-level review gates.
Product mascot animation
Animate a clearly framed mascot or spokesperson image from a controlled motion reference for campaign variants.
