Kling 3.0 Turbo Standard Text to Video

Build video scenes with Kling 3.0 Turbo Standard, using text and individual shot prompts to direct action and composition.

​

Available Models

• kwaivgi/kling-v3-turbo-std/text-to-video - Generate video scenes from text prompts.

​

Duration Options

• 3-15 seconds - Accepted range for an explicit duration. Without multi_prompt, the default is 5 seconds.
• Multi-shot output - Each shot accepts 1-15 seconds and defaults to 5. The total must not exceed 15 seconds.
• With multi_prompt, omit duration to use the shot total, including totals of 1 or 2 seconds. If supplied, duration must equal the shot total and remain within 3-15 seconds.

​

Key Features

• Generate video scenes from text prompts.
• Direct one scene with prompt, or use multi_prompt for up to six shots.

​

Advanced Parameters

Set model and optional callback_url at the request root. Place the parameters below inside input. Send only the input fields supported by this workflow. Unsupported input fields are rejected before credits are deducted. Input URLs must use HTTP(S), include a hostname, and contain no embedded credentials.

​

Prompt

• prompt is optional and supports up to 2,500 characters. Blank optional prompts are treated as omitted.
• Use either prompt or multi_prompt; do not combine them.

​

Multi-Prompt

• multi_prompt accepts 1-6 shot objects and cannot be combined with prompt.
• Each shot requires a nonblank prompt of at most 2,500 characters.
• Each shot can include an integer duration from 1 to 15 seconds; the default is 5 seconds.
• The combined shot duration must not exceed 15 seconds. See Duration Options for the top-level duration rules.
