Wan 3.0 Prime Reference-to-Video combines reference images, videos, and audio into a unified video with fast generation and strong multimodal coherence. It follows character identity, visual style, movement, and sound cues across references to create controlled, consistent, and production-ready results.

Generate a video from reference media with Wan 3.0 Prime.

1. Calling the API#

Install the client#

The client provides a convenient way to interact with the model API.

npm install --save @fal-ai/client

Migrate to @fal-ai/client

The @fal-ai/serverless-client package has been deprecated in favor of @fal-ai/client. Install the new package and update your imports — see client setup.

Setup your API Key#

Set FAL_KEY as an environment variable in your runtime.

export FAL_KEY="YOUR_API_KEY"

Submit a request#

The client API handles the API submit protocol. It will handle the request status updates and return the result when the request is completed.

import { fal } from "@fal-ai/client";

const result = await fal.subscribe("alibaba/wan-3.0-prime/reference-to-video", {
  input: {},
  logs: true,
  onQueueUpdate: (update) => {
    if (update.status === "IN_PROGRESS") {
      update.logs.map((log) => log.message).forEach(console.log);
    }
  },
});
console.log(result.data);
console.log(result.requestId);

2. Authentication#

The API uses an API Key for authentication. It is recommended you set the FAL_KEY environment variable in your runtime when possible.

API Key#

In an environment where you cannot set environment variables, you can configure the API key manually on the client.

import { fal } from "@fal-ai/client";

fal.config({
  credentials: "YOUR_FAL_KEY"
});

Protect your API Key

When running code on the client-side (e.g. in a browser, mobile app or GUI applications), make sure to not expose your FAL_KEY. Instead, use a server-side proxy to make requests to the API. For more information, check out our server-side integration guide.

3. Queue#

Long-running requests

For long-running requests, such as training jobs or models with slower inference times, it is recommended to check the Queue status and rely on Webhooks instead of blocking while waiting for the result.

Submit a request#

The client API provides a convenient way to submit requests to the model.

import { fal } from "@fal-ai/client";

const { request_id } = await fal.queue.submit("alibaba/wan-3.0-prime/reference-to-video", {
  input: {},
  webhookUrl: "https://optional.webhook.url/for/results",
});

Fetch request status#

You can fetch the status of a request to check if it is completed or still in progress.

import { fal } from "@fal-ai/client";

const status = await fal.queue.status("alibaba/wan-3.0-prime/reference-to-video", {
  requestId: "764cabcf-b745-4b3e-ae38-1200304cf45b",
  logs: true,
});

Get the result#

Once the request is completed, you can fetch the result. See the Output Schema for the expected result format.

import { fal } from "@fal-ai/client";

const result = await fal.queue.result("alibaba/wan-3.0-prime/reference-to-video", {
  requestId: "764cabcf-b745-4b3e-ae38-1200304cf45b"
});
console.log(result.data);
console.log(result.requestId);

4. Files#

Some attributes in the API accept file URLs as input. Whenever that's the case you can pass your own URL or a Base64 data URI.

Data URI (base64)#

You can pass a Base64 data URI as a file input. The API will handle the file decoding for you. Keep in mind that for large files, this alternative although convenient can impact the request performance.

Hosted files (URL)#

You can also pass your own URLs as long as they are publicly accessible. Be aware that some hosts might block cross-site requests, rate-limit, or consider the request as a bot.

Uploading files#

We provide a convenient file storage that allows you to upload files and use them in your requests. You can upload files using the client API and use the returned URL in your requests.

import { fal } from "@fal-ai/client";

const file = new File(["Hello, World!"], "hello.txt", { type: "text/plain" });
const url = await fal.storage.upload(file);

Auto uploads

The client will auto-upload the file for you if you pass a binary object (e.g. File, Data).

Read more about file handling in our file upload guide.

5. Schema#

Input#

prompt string

Text prompt directing how the reference media is used. Reference media can be addressed positionally, e.g. 'the subject in Image 1 walks past Video 1'.

resolution ResolutionEnum

Output video resolution tier. Default value: "1080p"

Possible enum values: 480p, 720p, 1080p

aspect_ratio AspectRatioEnum

Output aspect ratio, or adaptive selection. Default value: "adaptive"

Possible enum values: adaptive, 16:9, 4:3, 1:1, 3:4, 9:16

duration integer

Output duration in seconds. Set to null for smart duration, which lets the model pick a length from the prompt and reference media. Default value: 5

audio boolean

Include generated audio. Default value: true

enable_prompt_expansion boolean

Enable intelligent prompt rewriting. Disabling it can save roughly 20-60 seconds of latency but is likely to degrade generation quality. Default value: true

enable_thinking boolean

Enable enhanced reasoning before generation.

seed integer

enable_safety_checker boolean

Enable content moderation for input and output. Disabling it requires account authorization; unauthorized requests are always checked. Default value: true

reference_image_urls list<string>

Up to 10 reference image URLs.

reference_video_urls list<string>

Up to 5 reference video URLs totaling at most 15 seconds. Each clip must be at least 16 fps. Input video duration is billed in addition to output duration.

reference_audio_urls list<string>

Up to 5 reference audio URLs totaling at most 15 seconds.

file_url string

Document URL to base the video on. Requires enable_thinking=true.

web_url string

Public webpage URL to base the video on. Requires enable_thinking=true. Only pages that do not require login can be read.

{
  "resolution": "1080p",
  "aspect_ratio": "adaptive",
  "duration": 5,
  "audio": true,
  "enable_prompt_expansion": true,
  "enable_safety_checker": true
}

Output#

video VideoFile* required
