# WaveSpeedAI Veo 3.1 Fast Video Generation

Generate and extend videos using Google's Veo 3.1 Fast model via the WaveSpeed AI platform. Supports text-to-video, image-to-video, and video extension with up to 4K resolution and optional audio 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(
  "google/veo3.1-fast/text-to-video",
  { prompt: "A drone shot flying over a lush tropical island at sunrise" }
))["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';

const imageUrl = await wavespeed.upload("/path/to/photo.png");

const output_url = (await wavespeed.run(
  "google/veo3.1-fast/image-to-video",
  {
    image: imageUrl,
    prompt: "The flowers sway gently in the breeze"
  }
))["outputs"][0];

Video Extend

Extend a Veo-generated video by 7 seconds per run (up to 20 extensions, 148 seconds total):

// First, generate a video
const video_url = (await wavespeed.run(
  "google/veo3.1-fast/text-to-video",
  { prompt: "A cat walking through a garden" }
))["outputs"][0];

// Then extend it
const extended_url = (await wavespeed.run(
  "google/veo3.1-fast/video-extend",
  {
    video: video_url,
    prompt: "The cat jumps onto a fence and looks around"
  }
))["outputs"][0];

API Endpoints

Text-to-Video

**Model ID:** `google/veo3.1-fast/text-to-video`

Generate videos from text prompts with optional audio.

#### Parameters

|-----------|------|----------|---------|-------------|

#### Example

import wavespeed from 'wavespeed';

const output_url = (await wavespeed.run(
  "google/veo3.1-fast/text-to-video",
  {
    prompt: "A timelapse of a city skyline transitioning from day to night, cinematic",
    negative_prompt: "blurry, low quality",
    aspect_ratio: "16:9",
    duration: 8,
    resolution: "1080p",
    generate_audio: true
  }
))["outputs"][0];

Image-to-Video

**Model ID:** `google/veo3.1-fast/image-to-video`

Animate a source image into a video. Optionally provide an end-frame reference image.

#### Parameters

|-----------|------|----------|---------|-------------|

#### Example

import wavespeed from 'wavespeed';

const imageUrl = await wavespeed.upload("/path/to/landscape.png");

const output_url = (await wavespeed.run(
  "google/veo3.1-fast/image-to-video",
  {
    image: imageUrl,
    prompt: "Clouds drift slowly across the sky, water ripples gently",
    resolution: "1080p",
    duration: 8,
    generate_audio: true
  }
))["outputs"][0];

#### With End-Frame Reference

const startUrl = await wavespeed.upload("/path/to/start-frame.png");
const endUrl = await wavespeed.upload("/path/to/end-frame.png");

const output_url = (await wavespeed.run(
  "google/veo3.1-fast/image-to-video",
  {
    image: startUrl,
    last_image: endUrl,
    prompt: "Smooth transition from day to night"
  }
))["outputs"][0];

Video Extend

**Model ID:** `google/veo3.1-fast/video-extend`

Extend a Veo-generated video by 7 seconds per run. Input must be a Veo-generated video.

#### Parameters

|-----------|------|----------|---------|-------------|

#### Constraints

Input video **must be Veo-generated** (will not work with arbitrary videos)

Each run adds **+7 seconds** to the video

Maximum **20 extensions** in a chain

Maximum final video length: **148 seconds**

Output is a single MP4 (original + extension appended)

Aspect ratio and resolution are inherited from the input video

#### Example

import wavespeed from 'wavespeed';

// Generate an initial video
const video_url = (await wavespeed.run(
  "google/veo3.1-fast/text-to-video",
  {
    prompt: "A surfer catches a wave at golden hour",
    duration: 8
  }
))["outputs"][0];

// Extend it twice
const extended_once = (await wavespeed.run(
  "google/veo3.1-fast/video-extend",
  {
    video: video_url,
    prompt: "The surfer rides the wave toward shore"
  }
))["outputs"][0];

const extended_twice = (await wavespeed.run(
  "google/veo3.1-fast/video-extend",
  {
    video: extended_once,
    prompt: "The surfer steps off the board and walks on the beach"
  }
))["outputs"][0];

Advanced Usage

Without Audio

const output_url = (await wavespeed.run(
  "google/veo3.1-fast/text-to-video",
  {
    prompt: "A silent timelapse of stars rotating over a desert",
    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(
  "google/veo3.1-fast/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(
  "google/veo3.1-fast/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");
  }
}

Pricing

Text-to-Video / Image-to-Video

| Condition | Cost |

|-----------|------|

| With audio (720p or 1080p) | $1.20 per generation |

| Without audio (720p or 1080p) | $0.80 per generation |

Video Extend

| Condition | Cost |

|-----------|------|

| Per run (+7 seconds) | $1.05 |

Prompt Tips

Be specific about scene, style, subject actions, camera motion, and mood

Use `negative_prompt` to avoid artifacts: "blurry, low quality, distorted"

For image-to-video, use a clear, high-quality still image as input

For video extend, describe what should happen next in the scene

Video extend chains enable building longer narratives — up to 148 seconds total

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 prompt content and media URLs before sending requests.
