Wan Motion is a streamlined character animation model that transfers motion from a driving video onto a reference character image. Based on Wan-Animate which preserves the original character's proportions, Simple uses pose retargeting to adapt the driving video's skeleton to match the reference character's body shape, producing more natural results when the two have different builds. It outputs at 720p with optimized defaults for fast, high-quality generation — just provide a video, an image, and an optional prompt.

About

Simplified character animation endpoint. Takes a driving video and a reference image, transfers the motion to the character with retargeted pose.

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("fal-ai/wan-motion", {
  input: {
    video_url: "https://v3b.fal.media/files/b/0a8f0997/JuDW2xl0mr6sJ_Kjz3Vxe_vidoeook.mp4",
    image_url: "https://v3b.fal.media/files/b/0a8f0995/slF9l2eNL_YSD7SqU7tUz_i35fsR92.jpg"
  },
  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("fal-ai/wan-motion", {
  input: {
    video_url: "https://v3b.fal.media/files/b/0a8f0997/JuDW2xl0mr6sJ_Kjz3Vxe_vidoeook.mp4",
    image_url: "https://v3b.fal.media/files/b/0a8f0995/slF9l2eNL_YSD7SqU7tUz_i35fsR92.jpg"
  },
  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("fal-ai/wan-motion", {
  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("fal-ai/wan-motion", {
  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#

video_url string* required

URL of the driving video (provides the motion).

image_url string* required

URL of the reference image (provides the character appearance).

prompt string

Optional text prompt to guide the generation. Default value: ""

seed integer

Random seed for reproducibility.

acceleration AccelerationEnum

Acceleration level to use. 'regular' enables caching for faster generation, 'none' disables it. Default value: "regular"

Possible enum values: none, regular

adapt_motion boolean

Adapts the driving video's motion to match the reference image's body proportions. Recommended when the driving video subject and reference image have different body shapes or sizes. Default value: true

enhance_identity boolean

Enhances identity preservation by preprocessing the reference image with Flux Kontext Edit before animation. Produces more faithful face and appearance transfer at the cost of slightly longer processing time.

enable_safety_checker boolean

If set to true, input and output will be checked for safety. Disabling it requires account authorization; unauthorized requests are always checked. Default value: true

{
  "video_url": "https://v3b.fal.media/files/b/0a8f0997/JuDW2xl0mr6sJ_Kjz3Vxe_vidoeook.mp4",
  "image_url": "https://v3b.fal.media/files/b/0a8f0995/slF9l2eNL_YSD7SqU7tUz_i35fsR92.jpg",
  "prompt": "woman dancing",
  "acceleration": "regular",
  "adapt_motion": true,
  "enable_safety_checker": true
}

Output#

video File* required

The generated video file.

prompt string

The prompt used for generation. Default value: ""

seed integer* required

The seed used for generation.

{
  "video": {
    "url": "https://v3b.fal.media/files/b/0a8f2447/EjMyhbOyYfxL8tDM9T59K_wan_animate_output.mp4"
  },
  "prompt": "woman dancing",
  "seed": 924575000
}

Other types#

File#

url string* required
