# Kling 3 Standard - Generate video

> Generate AI video using Kling 3 Standard with text-to-video or image-to-video capabilities.

**Features:**
- **Text-to-video**: Generate videos from text prompts
- **Image-to-video**: Use start and/or end frame images to guide generation
- **Multi-shot**: Create videos with up to 6 shots (max 15s total)
- **Element control**: Include reference images for consistent character/style

**Duration:** 3-15 seconds
**Quality:** Standard mode offers faster generation at slightly lower quality compared to Pro.

            Required for text-to-video mode or when not using multi_prompt.


            **Tips for better results:**

            - Be specific about motion, camera angles, and actions

            - Describe the scene, characters, and atmosphere

            - Reference elements in your prompt as @Element1, @Element2

        multi_prompt:

            Multi-shot prompts with durations for sequential video generation.

            Each item specifies a prompt and duration (in seconds) for that
            shot.

            Maximum 6 shots. Total duration across all shots cannot exceed 15
            seconds.


            Only effective when shot_type is set. When multi_prompt is provided
            without an explicit shot_type, it defaults to "customize".

            When shot_type is "intelligent", Kling can auto-segment the video
            even without multi_prompt.

            - Minimum: 300x300 pixels

            Controls how multi-shot video generation is segmented:

            - `customize`: User provides explicit per-shot prompts and durations
            via the multi_prompt array. Each shot is defined manually.

            - `intelligent`: Enables automatic scene segmentation by Kling AI.
            Can be used without multi_prompt (Kling auto-segments the video
            based on the main prompt) or with multi_prompt (user-defined shots
            combined with AI segmentation).


            Note: This parameter maps to Kling's internal "intelligence"
            spelling for the intelligent option.

            Defaults to "customize" when multi_prompt is provided.

            - **0**: Maximum creative freedom, loosest interpretation of the
