Request Body

application/json

These parameters come from the selected model form_schema. Switching models updates this list and the request example.

Generation Mode

Choose the generation mode. Text to Video: generate from storyboard prompts only. Image to Video: upload a first-frame image (optional last frame) as the start/end of the video, combined with storyboard prompts. Only one mode at a time.

image*string

[Image to Video] The starting frame for video generation. JPG/PNG, ≤10MB, min 300px.

RequiredExample Value: https://p2-kling.klingai.com/kcdn/cdn-kcdn112452/kling-qa-test/multi-2.pngValue Range: 0 ≤ value ≤ 1

image_tail?string

[Image to Video] Optional. End-frame control for precise first-to-last frame transition.

Value Range: 0 ≤ value ≤ 1

multi_prompt*array

Add multiple shots with unique prompts and durations. Total duration must match the setting below. Each prompt up to 2500 characters.

RequiredExample Value: [{"index":1,"prompt":"A wide panoramic shot of a bustling futuristic city street at dusk, with neon lights reflecting on wet pavement.","duration":"5"},{"index":2,"prompt":"Cinematic transition to a detailed close-up following a pedestrian's cybernetic details.","duration":"5"}]

size?string

Output video resolution. Default 1080P.

Example Value: 1920x1080

Enum/Options:

1080P (1920x1080): 1920x1080720P (1280x720): 1280x7204K (3840x2160): 3840x2160

multi_shot?boolean

When enabled, multiple storyboard shots can be controlled separately.

Example Value: true

shot_type?string

Customize: you set each shot's prompt and duration; Intelligence: the model plans the shot layout automatically.

Example Value: customize

Enum/Options:

Customize: customizeIntelligence: intelligence

watermark_enabled?boolean

When enabled, the generated video carries a watermark. Disabled by default.

Example Value: false

negative_prompt?string

Describe content you don't want to see. Max 2500 characters.

Example Value: blurry, low quality, distorted, flicker, watermark

mode?string

Generation quality mode. Pro is higher quality but slower; Standard is faster. Pro is required when sound is enabled.

Example Value: pro

Enum/Options:

Professional (1080P): proStandard (720P): std

duration?number

Total video duration in seconds. In multi-shot mode it must equal the sum of shot durations. For single-shot the standard values are 5 or 10 seconds.

Example Value: 10Value Range: 5 ≤ value ≤ 15step: 1

cfg_scale?number

Prompt adherence, range 0-1, default 0.5. Higher values follow the prompt more strictly but reduce flexibility.

Example Value: 0.5Value Range: 0 ≤ value ≤ 1step: 0.1

sound?string

Whether to generate native audio matching the visuals. Pro mode is required when on.

Example Value: on

Enum/Options:

On: onOff: off
