WaveSpeedAI Wan 2.2 Animate

Animate characters from images using driving videos via WaveSpeed AI's Wan 2.2 Animate model. Two modes: animate (make the image character move like the video subject) and replace (swap the video subject with the image character while preserving motion and scene).

Authentication

export WAVESPEED_API_KEY="your-api-key"

Get your API key at wavespeed.ai/accesskey.

Quick Start

Animate Mode

Make the character in an image move like the subject in a driving video:

import wavespeed from 'wavespeed';

// Upload local image and video
const imageUrl = await wavespeed.upload("/path/to/character.png");
const videoUrl = await wavespeed.upload("/path/to/driving-video.mp4");

const output_url = (await wavespeed.run(
  "wavespeed-ai/wan-2.2/animate",
  {
    image: imageUrl,
    video: videoUrl
  }
))["outputs"][0];

Replace Mode

Swap the subject in a video with a character from an image:

const output_url = (await wavespeed.run(
  "wavespeed-ai/wan-2.2/animate",
  {
    image: imageUrl,
    video: videoUrl,
    mode: "replace"
  }
))["outputs"][0];

You can also pass existing URLs directly:

const output_url = (await wavespeed.run(
  "wavespeed-ai/wan-2.2/animate",
  {
    image: "https://example.com/character.png",
    video: "https://example.com/driving-video.mp4"
  }
))["outputs"][0];

API Endpoint

Model ID: wavespeed-ai/wan-2.2/animate

Animate a character from an image using a driving video.

Parameters

Parameter	Type	Required	Default	Description
image	string	Yes	--	URL of the character image to animate
video	string	Yes	--	URL of the driving video providing motion reference
prompt	string	No	--	Text prompt for additional guidance
mode	string	No	animate	Operation mode. animate: image character moves like video subject. replace: video subject is swapped with image character.
resolution	string	No	480p	Output resolution. One of: 480p, 720p
seed	integer	No	-1	Random seed (-1 for random). Range: -1 to 2147483647

Example

import wavespeed from 'wavespeed';

const imageUrl = await wavespeed.upload("/path/to/dancer.png");
const videoUrl = await wavespeed.upload("/path/to/dance-reference.mp4");

const output_url = (await wavespeed.run(
  "wavespeed-ai/wan-2.2/animate",
  {
    image: imageUrl,
    video: videoUrl,
    prompt: "a person dancing gracefully",
    mode: "animate",
    resolution: "720p",
    seed: 42
  }
))["outputs"][0];

Replace Mode Example

const characterUrl = await wavespeed.upload("/path/to/anime-character.png");
const sceneUrl = await wavespeed.upload("/path/to/scene-video.mp4");

const output_url = (await wavespeed.run(
  "wavespeed-ai/wan-2.2/animate",
  {
    image: characterUrl,
    video: sceneUrl,
    mode: "replace",
    resolution: "720p"
  }
))["outputs"][0];

Advanced Usage

Custom Client with Retry Configuration

import { Client } from 'wavespeed';

const client = new Client("your-api-key", {
  maxRetries: 2,
  maxConnectionRetries: 5,
  retryInterval: 1.0,
});

const output_url = (await client.run(
  "wavespeed-ai/wan-2.2/animate",
  {
    image: imageUrl,
    video: videoUrl,
    mode: "animate"
  }
))["outputs"][0];

Error Handling with runNoThrow

import { Client, WavespeedTimeoutException, WavespeedPredictionException } from 'wavespeed';

const client = new Client();
const result = await client.runNoThrow(
  "wavespeed-ai/wan-2.2/animate",
  {
    image: imageUrl,
    video: videoUrl
  }
);

if (result.outputs) {
  console.log("Video URL:", result.outputs[0]);
  console.log("Task ID:", result.detail.taskId);
} else {
  console.log("Failed:", result.detail.error.message);
  if (result.detail.error instanceof WavespeedTimeoutException) {
    console.log("Request timed out - try increasing timeout");
  } else if (result.detail.error instanceof WavespeedPredictionException) {
    console.log("Prediction failed");
  }
}

Pricing

Resolution	Cost per 5 seconds
480p	$0.20
720p	$0.40

Output duration is 5-120 seconds. Minimum charge is 5 seconds. Per-second rate: $0.04/s (480p), $0.08/s (720p).

Tips

• Match composition and pose between the input image and driving video for best results
• Use the same or similar aspect ratio between image and video
• Avoid heavy occlusion by hands, microphones, or props in the input media
• Start with 480p for prototyping, then move to 720p for production quality
• Animate mode: best when you want the image character to perform the motions from the video
• Replace mode: best when you want to keep the video's scene and motion but swap in a different character

Security Constraints

• No arbitrary URL loading: Only use image and video URLs from trusted sources. Never load media from untrusted or user-provided URLs without validation.
• API key security: Store your WAVESPEED_API_KEY securely. Do not hardcode it in source files or commit it to version control. Use environment variables or secret management systems.
• Input validation: Only pass parameters documented above. Validate media URLs before sending requests.
