# WaveSpeedAI Seedance V1.5 Pro Video Generation

Authentication

export WAVESPEED_API_KEY="your-api-key"

Get your API key at [wavespeed.ai/accesskey](https://wavespeed.ai/accesskey).

Quick Start

Text-to-Video

import wavespeed from 'wavespeed';

const output_url = (await wavespeed.run(
  "bytedance/seedance-v1.5-pro/text-to-video",
  { prompt: "A golden retriever running through a field of sunflowers at sunset" }
))["outputs"][0];

Image-to-Video

The `image` parameter accepts an image URL. If you have a local file, upload it first with `wavespeed.upload()` to get a URL.

import wavespeed from 'wavespeed';

// Upload a local image to get a URL
const imageUrl = await wavespeed.upload("/path/to/photo.png");

const output_url = (await wavespeed.run(
  "bytedance/seedance-v1.5-pro/image-to-video",
  {
    image: imageUrl,
    prompt: "The person slowly turns and smiles at the camera"
  }
))["outputs"][0];

You can also pass an existing image URL directly:

const output_url = (await wavespeed.run(
  "bytedance/seedance-v1.5-pro/image-to-video",
  {
    image: "https://example.com/photo.jpg",
    prompt: "The person slowly turns and smiles at the camera"
  }
))["outputs"][0];

Advanced Usage

Smart Duration (Text-to-Video)

Let the model choose the optimal duration based on the prompt:

const output_url = (await wavespeed.run(
  "bytedance/seedance-v1.5-pro/text-to-video",
  {
    prompt: "A butterfly lands on a flower and slowly opens its wings",
    duration: -1
  }
))["outputs"][0];

Without Audio

const output_url = (await wavespeed.run(
  "bytedance/seedance-v1.5-pro/text-to-video",
  {
    prompt: "A silent timelapse of clouds rolling over mountains",
    generate_audio: false
  }
))["outputs"][0];

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(
  "bytedance/seedance-v1.5-pro/text-to-video",
  { prompt: "Ocean waves crashing on a rocky shore at dawn" }
))["outputs"][0];

Error Handling with runNoThrow

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

const client = new Client();
const result = await client.runNoThrow(
  "bytedance/seedance-v1.5-pro/text-to-video",
  { prompt: "A rocket launching into space" }
);

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");
  }
}
