Video Geneartion

Installation

JavaScript

npm install solvid

Authentication

1. Get a key from https://api.solvid.xyz (coming soon)

In JavaScript, you can pass the API key using the authToken parameter when creating the client.

JavaScript

const { SolVid } = require('solvid');

const client = new SolVid ({
  authToken: process.env.SOLVID_API_KEY
});

Polling for Generation Status and Retrieving Video

In JavaScript, use async/await for handling the polling.

Javascript

npm install node-fetch

Javascript

const fetch = require('node-fetch');
const fs = require('fs');
const { LumaAI } = require('lumaai');

const client = new SolVid ({ authToken: process.env.SOLVID_API_KEY});

async function generateVideo() {
    let generation = await client.generations.create({
        prompt: "A teddy bear in sunglasses playing electric guitar and dancing"
    });

    let completed = false;

    while (!completed) {
        generation = await client.generations.get(generation.id);

        if (generation.state === "completed") {
            completed = true;
        } else if (generation.state === "failed") {
            throw new Error(`Generation failed: ${generation.failure_reason}`);
        } else {
            console.log("Dreaming...");
            await new Promise(r => setTimeout(r, 3000)); // Wait for 3 seconds
        }
    }

    const videoUrl = generation.assets.video;

    const response = await fetch(videoUrl);
    const fileStream = fs.createWriteStream(`${generation.id}.mp4`);
    await new Promise((resolve, reject) => {
        response.body.pipe(fileStream);
        response.body.on('error', reject);
        fileStream.on('finish', resolve);
    });

    console.log(`File downloaded as ${generation.id}.mp4`);
}

generateVideo();

Text to Video

Text to Video Generation Example

JavaScript

const generation = await client.generations.create({
  prompt: "A teddy bear in sunglasses playing electric guitar and dancing"
});

Image to Video

With start frame

JavaScript

const generation = await client.generations.create({
  prompt: "Low-angle shot of a majestic tiger prowling through a snowy landscape, leaving paw prints on the white blanket",
  keyframes: {
    frame0: {
      type: "image",
      url: "https://your-image-url.com/start-frame.jpg"
    }
  }
});

With start frame, loop

JavaScript

const generation = await client.generations.create({
  prompt: "Low-angle shot of a majestic tiger prowling through a snowy landscape, leaving paw prints on the white blanket",
  keyframes: {
    frame0: {
      type: "image",
      url: "https://your-image-url.com/start-frame.jpg"
    }
  },
  loop: true,
});

With end frame, loop

JavaScript

const generation = await client.generations.create({
  prompt: "Low-angle shot of a majestic tiger prowling through a snowy landscape, leaving paw prints on the white blanket",
  keyframes: {
    frame1: {
      type: "image",
      url: "https://your-image-url.com/start-frame.jpg"
    }
  },
  loop: true,
});

Extend video

Extending Video

Extend is currently supported only for generated videos. Please make sure the generation is in completed state before passing it

JavaScript

const generation = await client.generations.create({
  prompt: "A teddy bear in sunglasses playing electric guitar and dancing",
  keyframes: {
    frame0: {
      type: "generation",
      id: "d1968551-6113-4b46-b567-09210c2e79b0"
    }
  }
});

Reverse Extend Video

Extend is currently supported only for generated videos. Please make sure the generation is in completed state before passing it

JavaScript

const generation = await client.generations.create({
  prompt: "A teddy bear in sunglasses playing electric guitar and dancing",
  keyframes: {
    frame1: {
      type: "generation",
      id: "d1968551-6113-4b46-b567-09210c2e79b0"
    }
  }
});

Interpolating Between Two Generated Videos

Interpolate is currently supported only for generated videos. Please make sure the generation is in completed state before passing it

Javascript

const generation = await client.generations.create({
  prompt: "A teddy bear in sunglasses playing electric guitar and dancing",
  keyframes: {
    frame0: {
      type: "generation",
      id: "d312d37a-7ff4-49f2-94f8-218f3fe2a4bd"
    },
    frame1: {
      type: "generation",
      id: "d1968551-6113-4b46-b567-09210c2e79b0"
    }
  }
});

Generations

Get generation with id

Javascript

const generation = await client.generations.get("4fac0ef4-b336-45bf-a5dc-6de436cfbd62");

List all generations

Javascript

const generation = await client.generations.list();

Delete generation

Javascript

const generation = await client.generations.delete("4fac0ef4-b336-45bf-a5dc-6de436cfbd62");

Camera Motions

Get all supported camera motions

Javascript

const cameras = await client.generations.cameraMotion.list();

How to get a callback when generation has an update

• It will get status updates (dreaming/completed/failed)

• It will also get the video url as part of it when completed

• It's a POST endpoint you can pass, and request body will have the generation object in it

• It expected to be called multiple times for a status

• If the endpoint returns a status code other than 200, it will be retried max 3 times with 100ms delay and the request has a 5s timeout

example

TypeScript

const generation = await client.generations.create({
  prompt: "A teddy bear in sunglasses playing electric guitar and dancing",
  callback_url: "<your_api_endpoint_here>"
});
