Kling V3 Turbo Pro Text to Video API

Kling V3 Turbo Pro Text-to-Video

Kling V3 Turbo Pro Text-to-Video generates high quality 1080p videos from text prompts. It supports both single-prompt generation and multi-shot storyboard generation with per-shot durations.

Why Choose This?

High quality 1080p video generation
Create polished pro-tier videos directly from text prompts.
Fast turbo inference
Use the turbo version for faster generation while keeping strong visual quality.
Single prompt or multi-shot storyboard
Generate a complete video from one prompt, or use multi_prompt to define multiple shots.
Per-shot duration control
Set each storyboard segment duration when using multi_prompt.
Standard video output
The generated video is returned as a URL in the standard WaveSpeed prediction response.

Parameters

Parameter	Required	Description
prompt	No	Text prompt describing the video to generate. Mutually exclusive with `multi_prompt`.
multi_prompt	No	Multi-shot storyboard. Each item includes a prompt and duration. Mutually exclusive with `prompt`.
aspect_ratio	No	Output aspect ratio. Options: `16:9`, `9:16`, `1:1`. Default: `16:9`.
duration	No	Video duration in seconds for single-prompt generation. Options: `3` to `15`. Default: `5`.

How to Use

Enter a prompt — Describe the scene, subject, motion, and style you want.
Or create a storyboard — Use multi_prompt to define multiple shots with individual durations.
Choose aspect ratio — Select 16:9, 9:16, or 1:1.
Set duration — Choose the video duration for single-prompt generation, or set durations per shot in multi_prompt.
Submit — Generate the video output.

Output

Returns generated video URL(s) in the standard WaveSpeed prediction response.

The generated video is returned as MP4 video.

Pricing

Pricing is $0.14 per second.

WaveSpeed bills by the generated video duration. If multi_prompt is provided, billing uses the selected duration plus the sum of all segment durations.

Generated Duration	Price
3s	$0.42
5s	$0.70
10s	$1.40
15s	$2.10

Billing Rules

Billing is based on generated video duration.
Single-prompt requests use the duration parameter.
multi_prompt requests use duration plus the sum of all segment durations.
Each second costs $0.14.

Best Use Cases

Text-to-video creation — Turn written concepts into finished video clips.
Storyboard generation — Build multi-shot videos with separate prompts per segment.
Advertising concepts — Prototype product, brand, or social video ideas.
Cinematic scene generation — Create visually rich scenes with controlled aspect ratio.
Creative iteration — Test variations of motion, camera direction, and scene style.

Pro Tips

Use clear subject, action, camera, and style details in the prompt.
Use multi_prompt when you need multiple shots instead of one continuous prompt.
Keep total multi_prompt duration within the model limit.
Use consistent wording across storyboard segments for better visual continuity.
Choose the aspect ratio before writing composition-heavy prompts.

Notes

Provide either prompt or multi_prompt.
prompt and multi_prompt are mutually exclusive.
duration is used for single-prompt generation.
multi_prompt supports per-shot durations.
The total generated duration must not exceed 15 seconds.
