Kling VIDEO 2.6 Standard

Kling AI
by Kling AI

Kling VIDEO 2.6 Standard is a high-quality AI video generation model focused on producing visually coherent short clips with stable motion, expressive camera movement, and strong prompt adherence. It generates video from text prompts or an optional input image, making it suitable for cinematic previews, social content, and creative prototyping where audio is not required.

API Options

Platform-level options for task execution and delivery.

taskType

string required value: videoInference

Identifier for the type of task being performed

taskUUID

string required UUID v4

UUID v4 identifier for tracking tasks and matching async responses. Must be unique per task.

outputType

string default: URL

Video output type.

Allowed values 1 value

outputFormat

string default: MP4

File format for the generated video.

Allowed values 3 values

outputQuality

integer min: 20 max: 99 default: 95

Compression quality of the output. Higher values preserve quality but increase file size.

webhookURL

string URI

Specifies a webhook URL where JSON responses will be sent via HTTP POST when generation tasks complete. For batch requests with multiple results, each completed item triggers a separate webhook call as it becomes available.

deliveryMethod

string default: async

Determines how the API delivers task results.

Allowed values 1 value
Returns an immediate acknowledgment with the task UUID. Poll for results using getResponse. Required for long-running tasks like video generation.

uploadEndpoint

string URI

Specifies a URL where the generated content will be automatically uploaded using the HTTP PUT method. The raw binary data of the media file is sent directly as the request body. For secure uploads to cloud storage, use presigned URLs that include temporary authentication credentials.

Common use cases:

  • Cloud storage: Upload directly to S3 buckets, Google Cloud Storage, or Azure Blob Storage using presigned URLs.
  • CDN integration: Upload to content delivery networks for immediate distribution. 
// S3 presigned URL for secure upload
https://your-bucket.s3.amazonaws.com/generated/content.mp4?X-Amz-Signature=abc123&X-Amz-Expires=3600

// Google Cloud Storage presigned URL
https://storage.googleapis.com/your-bucket/content.jpg?X-Goog-Signature=xyz789

// Custom storage endpoint
https://storage.example.com/uploads/generated-image.jpg

The content data will be sent as the request body to the specified URL when generation is complete.

safety

object

Content safety checking configuration for video generation.

Properties 2 properties
safety » checkContent

checkContent

boolean default: false

Enable or disable content safety checking. When enabled, defaults to 'fast' mode.

safety » mode

mode

string default: none

Safety checking mode for video generation.

Allowed values 3 values
Disables checking.
Checks key frames.
Checks all frames.

ttl

integer min: 60

Time-to-live (TTL) in seconds for generated content. Only applies when outputType is 'URL'.

includeCost

boolean default: false

Include task cost in the response.

numberResults

integer min: 1 max: 20 default: 1

Number of results to generate. Each result uses a different seed, producing variations of the same parameters.

Inputs

Input resources for the task (images, audio, etc). These must be nested inside the inputs object.
inputs » frameImages

frameImages

array of objects min items: 1max items: 2

For image-to-video workflows, each item can be a plain image input (UUID, URL, Data URI, or Base64), or an object with an explicit frame position.

When no frame is specified, images are distributed automatically:

  • 1 image: First frame.
  • 2 images: First and last frames.
  • 3+ images: First and last frames, intermediates evenly spaced.
