Create Storyboard Preview

​
Overview

The Storyboard Preview API generates a preview of your video project, allowing you to review the storyboard structure, scene breakdown, visual selections, and configuration before committing to the final render. This is an essential step in the video creation workflow that helps you validate your content and make adjustments without incurring full rendering costs.
The storyboard preview creates a project with scene thumbnails and metadata. To generate the final rendered video, use the Render from Preview API after reviewing and approving the preview.
Recommended Workflow: Create Preview → Review Scenes → Make Adjustments → Render Final Video

​

​
object

​
aiVisual Object

AI-generated visual configuration. Use with background.type set to "image" for AI-generated images or "video" for AI-generated video clips.
The following fields are nested inside the aiVisual object, which is a property of scenes[].background. For example, scenes[].background.aiVisual.prompt means prompt is a property of aiVisual, which itself is nested inside background, inside each item of the scenes array.
​
string
Text prompt describing the visual to generate (max 500 characters). If omitted, the system auto-generates a prompt from the scene’s story text.When a story is split into multiple scenes (using createSceneOnEndOfSentence or createSceneOnNewLine), this prompt acts as a creative direction for the entire video rather than a prompt for a specific scene. The system uses it to guide the auto-generated prompts for each individual scene, ensuring a consistent visual tone. A good creative direction prompt follows this structure: [Action/Movement] + [Scene/Environment] + [Camera Technique] + [Visual Style]. For example: "Smooth cinematic tracking shots in modern creative workspaces with warm golden-hour lighting and shallow depth of field".
​
string
required
AI model to use. The valid options depend on background.type:Image models (when type is "image"): flux-schnell, seedream3.0, nanobanana, nanobanana-proVideo models (when type is "video"): pixverse5.5, veo3.1_fast, veo3.1
​
string
Visual style for generated images. Only applicable when type is "image". Options: photorealistic, artistic, cartoon, minimalist, vintage, futuristic
​
string
Duration of the generated video clip. Only applicable when type is "video". Valid values depend on the model:
  • pixverse5.5: "5s", "8s", "10s" (default: "5s")
  • veo3.1_fast: "4s", "6s", "8s" (default: "4s")
  • veo3.1: "4s", "6s", "8s" (default: "4s")
If omitted or invalid, the model’s shortest duration is used.
​
boolean
When set to true, enables visual continuity between consecutive AI-generated scenes. The system automatically uses the output of the previous scene as a reference for the next scene, creating smooth visual transitions. For video scenes, the last frame of the previous video is used. For image scenes, the generated image of the previous scene is used. This field works with both "video" and "image" types.Visual continuity applies in two scenarios:
  • Within the same story: Consecutive scenes that were split from the same original story use the previous scene’s output as a reference for the next scene.
  • Across consecutive stories: Continuity is also maintained between the last scene of one story and the first scene of the next story, enabling seamless transitions across story boundaries.
In both cases, visualContinuity must be set to true for the system to use the previous scene’s output as a reference. If visualContinuity is not set or is false, the following behavior applies for consecutive scenes from the same story:
  • Image scenes: All user-provided reference images (such as referenceImageUrl) are cleared, and visuals are generated independently.
  • Video scenes: Only firstFrameImageUrl is cleared if it was provided. However, referenceImageUrls are preserved and still used for generation.
This field has no effect on the first scene in a sequence. When continuity is active and the previous scene’s output is unavailable, the system falls back to generating the visual without a reference image.
​
string
URL of an image to use as the first frame of the generated video clip. The AI model generates a video that begins from this image and transitions into the content described in the prompt. Only applicable when type is "video". Cannot be used together with referenceImageUrls.
​
string
URL of a reference image to guide the style and composition of the generated image. Only applicable when type is "image". For video generation, use firstFrameImageUrl or referenceImageUrls instead.
​
string[]
An array of 1–2 reference image URLs to guide the style and composition of the generated video clip. Only applicable when type is "video". Cannot be used together with firstFrameImageUrl. For image generation, use referenceImageUrl instead.
When using referenceImageUrls (without firstFrameImageUrl) with the veo3.1 or veo3.1_fast models, the video duration is automatically set to "8s".

​
Reference Image Fields: Quick Reference

Mutual exclusivity rules:
  • firstFrameImageUrl and referenceImageUrls cannot be provided together. Use one or the other.
  • referenceImageUrl is only for image generation. For video generation, use firstFrameImageUrl or referenceImageUrls.
  • firstFrameImageUrl and referenceImageUrls are only for video generation. For image generation, use referenceImageUrl.

​
string
Horizontal offset as a percentage from the left, e.g. "10%". Cannot be combined with position.
​
string
Element width as a percentage of the canvas, e.g. "30%". For media elements, omitting width enables automatic sizing: the element starts at 30% of the canvas and shrinks so it stays fully on screen given its position and aspect ratio.

For example, scenes[].transcript[].speakerId means speakerId is a property of each item in the transcript array, which itself is nested inside each item of the scenes array.

​
templateOverride.layers Array

Layers allow you to customize text, image, and video elements within template scenes.
The following fields are nested inside the scenes[].templateOverride.layers structure, which is an array of arrays. The [][] notation indicates that layers is an array of arrays: the outer [] represents each subtitle group, and the inner [] represents each layer element within that group. For example, scenes[].templateOverride.layers[][].layerId means layerId is a property of each layer element inside the nested array structure.
​
string

​
Response

When the storyboard request is successfully submitted, a job is created and a job ID is returned. Use this job ID to poll the Get Storyboard Preview Job by ID endpoint for the completed storyboard preview.
​
boolean
Indicates whether the request was successful
​
object
Contains the storyboard job information
​
string
Unique identifier for the storyboard preview job. Use this to track the job status and retrieve results via the Get Storyboard Preview Job by ID endpoint.

​
Next Steps

Once you have the jobId, poll the Get Storyboard Preview Job by ID endpoint to check the job status and retrieve the completed storyboard preview. Use a polling interval of 10–30 seconds. When the job completes, you will receive:
  • renderParams: The rendering data for the video. To customize the video, update this data and use the Render Video API to render with your modifications. To update the preview with changes, save the updated data using the Update Storyboard Elements API.
  • storyboard: The processed input storyboard. If you want to change anything in the original storyboard request, use this processed response to make a new request with updates; it will process faster since the storyboard is already broken down into scenes, voices, and other components.
  • previewUrl: The preview URL for the video storyboard. Use this to view the preview in a browser or embed it in an iframe for app integrations. See the Embed Preview Player guide for details.
