Extend Video

Overview

You can extend a video using an existing video you generated before (using its ID) or by using an image (by URL). The extension can be done by appending to or prepending from the original content.

Keywords

The keywords parameter controls the following extensions. It can include parameters for defining frames:

• first frame (frame0)
• last frame (frame1)

For example, if you want to use an image as a reference for a frame:

{
        "keyframes": {
            "frame0": {
                "type": "image",
                "url": "https://example.com/image1.png"
            }
        }
}

Or, in the case of using a previously generated video:

{
    "keyframes": {
        "frame1": {
            "type": "generation",
            "id": "0f3ea4aa-10e7-4dae-af0b-263ab4ac45f9"
        }
    }
}

Examples

Ensure you replace "my_key" with your actual API key before running the code.

Extension with the Image

JavaScript

const main = async () => {
  const response = await fetch('https://api.umamiai.xyz/v2/generate/video/luma-ai/generation', {
    method: 'POST',
    headers: {
      Authorization: 'Bearer YOUR_UMAMIAI_API_KEY',
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      prompt: 'A jellyfish in the ocean',
      aspect_ratio: '19:9',
      keyframes: {
        frame0: {
          type: 'image',
          url: 'https://example.com/image1.png',
        },
      },
    }),
  }).then((res) => res.json());

  console.log('Generation:', response);
};

main();

Python

import requests


def main()
  url = "https://api.umamiai.xyz/v2/generate/video/luma-ai/generation"
  payload = {
    "prompt": "Flying jellyfish",
    "aspect_ratio": "16:9",
    "keyframes": {
      "frame0": {
        "type": "image",
        "url": "https://example.com/image1.png"
      }
    }
  }
  headers = {
    "Authorization": "Bearer YOUR_UMAMIAI_API_KEY",
    "Content-Type": "application/json"
  }
  
  response = requests.post(url, json=payload, headers=headers)
  print("Generation:",  response.json())
  
if __name__ == "__main__":
    main()

Extension with the Generation

JavaScript

const main = async () => {
  const response = await fetch('https://api.umamiai.xyz/v2/generate/video/luma-ai/generation', {
    method: 'POST',
