About

Generate a video from an image and text prompt using OpenAI's Sora 2 model.

1. Calling the API#

Install the client#

The client provides a convenient way to interact with the model API.

npm install --save @fal-ai/client

Setup your API Key#

Set FAL_KEY as an environment variable in your runtime.

export FAL_KEY="YOUR_API_KEY"

Submit a request#

The client API handles the API submit protocol. It will handle the request status updates and return the result when the request is completed.

import { fal } from "@fal-ai/client";

const result = await fal.subscribe("fal-ai/sora-2/image-to-video", {
  input: {
    prompt: "Front-facing 'invisible' action-cam on a skydiver in freefall above bright clouds; camera locked on his face. He speaks over the wind with clear lipsync: 'This is insanely fun! You've got to try it—book a tandem and go!' Natural wind roar, voice close-mic'd and slightly compressed so it's intelligible. Midday sun, goggles and jumpsuit flutter, altimeter visible, parachute rig on shoulders. Energetic but stable framing with subtle shake; brief horizon roll. End on first tug of canopy and wind noise dropping.",
    image_url: "https://storage.googleapis.com/falserverless/example_inputs/sora-2-i2v-input.png"
  },
  logs: true,
  onQueueUpdate: (update) => {
    if (update.status === "IN_PROGRESS") {
      update.logs.map((log) => log.message).forEach(console.log);
    }
  },
});
console.log(result.data);
console.log(result.requestId);

2. Authentication#

The API uses an API Key for authentication. It is recommended you set the FAL_KEY environment variable in your runtime when possible.

API Key#

In case your app is running in an environment where you cannot set environment variables, you can set the API Key manually as a client configuration.
import { fal } from "@fal-ai/client";

fal.config({
  credentials: "YOUR_FAL_KEY"
});

3. Queue#

Submit a request#

The client API provides a convenient way to submit requests to the model.

import { fal } from "@fal-ai/client";

const { request_id } = await fal.queue.submit("fal-ai/sora-2/image-to-video", {
  input: {
    prompt: "Front-facing 'invisible' action-cam on a skydiver in freefall above bright clouds; camera locked on his face. He speaks over the wind with clear lipsync: 'This is insanely fun! You've got to try it—book a tandem and go!' Natural wind roar, voice close-mic'd and slightly compressed so it's intelligible. Midday sun, goggles and jumpsuit flutter, altimeter visible, parachute rig on shoulders. Energetic but stable framing with subtle shake; brief horizon roll. End on first tug of canopy and wind noise dropping.",
    image_url: "https://storage.googleapis.com/falserverless/example_inputs/sora-2-i2v-input.png"
  },
  webhookUrl: "https://optional.webhook.url/for/results",
});

Fetch request status#

You can fetch the status of a request to check if it is completed or still in progress.

import { fal } from "@fal-ai/client";

const status = await fal.queue.status("fal-ai/sora-2/image-to-video", {
  requestId: "764cabcf-b745-4b3e-ae38-1200304cf45b",
  logs: true,
});

Get the result#

Once the request is completed, you can fetch the result. See the Output Schema for the expected result format.

import { fal } from "@fal-ai/client";

const result = await fal.queue.result("fal-ai/sora-2/image-to-video", {
  requestId: "764cabcf-b745-4b3e-ae38-1200304cf45b"
});
console.log(result.data);
console.log(result.requestId);

4. Files#

Some attributes in the API accept file URLs as input. Whenever that's the case you can pass your own URL or a Base64 data URI.

Data URI (base64)#

You can pass a Base64 data URI as a file input. The API will handle the file decoding for you. Keep in mind that for large files, this alternative although convenient can impact the request performance.

Hosted files (URL)#

You can also pass your own URLs as long as they are publicly accessible. Be aware that some hosts might block cross-site requests, rate-limit, or consider the request as a bot.

Uploading files#

We provide a convenient file storage that allows you to upload files and use them in your requests. You can upload files using the client API and use the returned URL in your requests.

import { fal } from "@fal-ai/client";

const file = new File(["Hello, World!"], "hello.txt", { type: "text/plain" });
const url = await fal.storage.upload(file);

Read more about file handling in our file upload guide.
