About

Video To Video

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("sonilo/v1.1/video-to-video", {
  input: {
    video_url: "https://v3b.fal.media/files/b/0a9ddd00/2QssaYyFxstvVlmIraSns_Sonilo_Demo_Original_1.mp4"
  },
  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("sonilo/v1.1/video-to-video", {
  input: {
    video_url: "https://v3b.fal.media/files/b/0a9ddd00/2QssaYyFxstvVlmIraSns_Sonilo_Demo_Original_1.mp4"
  },
  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("sonilo/v1.1/video-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("sonilo/v1.1/video-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.

5. Schema#

Input#

video_url string* required

Public http(s) URL of the source video to score.

keep_speech_vocal boolean

Keep the original video's speech/vocals. When on, the source audio is separated (music source separation), and only the isolated vocals are blended over the generated music with automatic ducking (the music dips under speech). When off (default), the original soundtrack is dropped and the video carries only the generated music.

num_samples integer

How many distinct scored videos to generate. Default value: 1

prompt string

Optional text prompt steering the musical style. If omitted, a prompt is generated automatically from the video.

start_offset float

Optional. Start scoring from this offset (seconds) into the video. Requires Start Offset + Duration <= Video Duration.

duration float

Optional. Length (seconds) of the video segment to score. When set, scores a segment of this length starting at Start Offset (or from the beginning if Start Offset is unset). Defaults (None) to the rest of the video.

{
  "video_url": "https://v3b.fal.media/files/b/0a9ddd00/2QssaYyFxstvVlmIraSns_Sonilo_Demo_Original_1.mp4",
  "num_samples": 1
}

Output#

video Video* required

The first scored video (source video muxed with generated music).

videos list<Video>* required

All scored videos (mp4), one per sample.
