Muapi Character Story Video

Character Story Video

Create a multi-part animated story video by first establishing a consistent character and then generating sequential scenes and animating them.

Inputs

| Name | Type | Required | Default | Description |

|:---|:---|:---|:---|:---|

| character_description | text | yes | — | Description of the main character (e.g. "a cute piglet wearing a leather aviator jacket and goggles"). |

| story_premise | text | yes | — | The overall story arc (e.g. "building a jetpack and flying to space"). |

| reference_image | image_url | no | — | Optional starting image of the character to maintain consistency. |

Steps

This skill involves multiple phases to build a cohesive narrative.

Phase A — Character Establishment

If {{reference_image}} is NOT provided, submit the plan with ONE step to create the character:

• Character Creation — muapi image generate (model=nano-banana-pro):
• Prompt: {{character_description}}, introducing the main character, cinematic lighting, highly detailed, Pixar 3D animation style.
• Aspect ratio: 4:5 or 1:1

If {{reference_image}} IS provided, use it as the established character and proceed to Phase B.

After generation, ask the user to confirm the character design before proceeding.

Phase B — Sequential Scene Generation

Once the character is established, create the story beats (e.g., Scene 1, Scene 2, Scene 3).

Submit the plan using muapi image edit (model=nano-banana-2-edit or flux-kontext-pro-i2i) to maintain character consistency. Use the established character image as the reference for ALL these steps.

• Scene 1 (Beginning)
• Reference: Character Image
• Prompt: The character ({{character_description}}) in the first scene of the story: [Describe the beginning of {{story_premise}}]. Cinematic lighting, Pixar 3D animation style, storybook illustration.
• Scene 2 (Middle)
• Reference: Character Image
• Prompt: The character ({{character_description}}) in the second scene: [Describe the climax or middle action of {{story_premise}}]. Cinematic lighting, Pixar 3D animation style, storybook illustration.
• Scene 3 (End)
• Reference: Character Image
• Prompt: The character ({{character_description}}) in the final scene: [Describe the resolution of {{story_premise}}]. Cinematic lighting, Pixar 3D animation style, storybook illustration.

*Note: All scenes should be generated in parallel or sequentially depending on the story flow.*

After generating the scenes, present them to the user and ask if they are ready to animate the story.

Phase C — Animation (Sequel Part 1, Part 2, Part 3)

Submit the plan to animate the generated scenes using an image-to-video model (e.g., kling-v3.0-pro-image-to-video or veo3.1-image-to-video).

• Part 1 Video
• Input: Scene 1 Image
• Prompt: Cinematic animation of the scene, character comes to life, subtle natural movements, high quality 3D animation.
• Part 2 Video
• Input: Scene 2 Image
• Prompt: Cinematic animation of the scene, character comes to life, dynamic action, high quality 3D animation.
• Part 3 Video
• Input: Scene 3 Image
• Prompt: Cinematic animation of the scene, character comes to life, triumphant resolution, high quality 3D animation.

After generating the videos, present them to the user as a multi-part story sequence. You may also suggest using the muapi predict result + ffmpeg concat tool to merge them into a single movie if requested.

Notes for the Executing Agent

• This recipe is LLM-orchestrated: read each phase, gather any missing inputs from the user, then call muapi CLI commands. Use muapi auth configure first if MUAPI_API_KEY is unset.
• For model IDs without a CLI alias yet, fall back to the raw endpoint via curl -X POST https://api.muapi.ai/api/v1/<endpoint> -H "x-api-key: $MUAPI_API_KEY" -H 'content-type: application/json' -d '{...}' and poll with muapi predict wait <request_id>.
• Substitute {{input_name}} placeholders with the user's actual inputs before issuing each call.
