About

Dubbing Pro

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

Migrate to @fal-ai/client

The @fal-ai/serverless-client package has been deprecated in favor of @fal-ai/client. Install the new package and update your imports — see client setup.

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("veed/dubbing/pro", {
  input: {
    video_url: "https://v3.fal.media/files/monkey/q1fDPhrpfjfsaRmbhTed4_influencer.mp4",
    target_language: "es"
  },
  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 an environment where you cannot set environment variables, you can configure the API key manually on the client.

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

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

Protect your API Key

When running code on the client-side (e.g. in a browser, mobile app or GUI applications), make sure to not expose your FAL_KEY. Instead, use a server-side proxy to make requests to the API. For more information, check out our server-side integration guide.

3. Queue#

Long-running requests

For long-running requests, such as training jobs or models with slower inference times, it is recommended to check the Queue status and rely on Webhooks instead of blocking while waiting for the result.

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("veed/dubbing/pro", {
  input: {
    video_url: "https://v3.fal.media/files/monkey/q1fDPhrpfjfsaRmbhTed4_influencer.mp4",
    target_language: "es"
  },
  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("veed/dubbing/pro", {
  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("veed/dubbing/pro", {
  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);

Auto uploads

The client will auto-upload the file for you if you pass a binary object (e.g. File, Data).

Read more about file handling in our file upload guide.

5. Schema#

Input#

video_url string* required

Video to dub, up to 10 minutes long and with speech in its audio track. The speech is translated into the target language, and the speakers' lips are synced to the dubbed voices.

target_language TargetLanguageEnum* required

Language to dub into, optionally with a regional dialect (e.g. 'es-MX', 'pt-BR'). Case-insensitive; for a language without dialects the region is ignored ('de-DE' = 'de'), and an unsupported dialect is rejected.

Possible enum values: af, ak, am, ar, ar-EG, as, az, be, bg, bo, bs, ca, ceb, cmn, cs, cy, da, de, dgo, el, en, en-AU, en-CA, en-GB, en-US, es, es-AR, es-CL, es-ES, es-MX, et, eu, fa, fi, fil, fr, fr-CA, fr-FR, gl, gu, ha, he, hi, hr, hu, hy, id, is, it, ja, jv, ka, ki, kk, kn, ko, ky, lg, lt, lv, mk, ml, mn, mr, ms, my, ne, nl, no, nso, pa, pl, pt, pt-BR, pt-PT, rn, ro, ru, rw, sd, sk, sl, sq, ss, st, su, sv, sw, ta, te, tg, th, tn, tr, ts, ug, uk, ur, uz, ve, vi, war, wo, yo, yue, zh, zh-TW, zu

source_language SourceLanguageEnum

Language spoken in the video. 'auto' (the default) detects it; set it explicitly if detection picks the wrong language. Default value: "auto"

Possible enum values: auto, af, ak, am, ar, as, az, be, bg, bo, bs, ca, ceb, cmn, cs, cy, da, de, dgo, el, en, es, et, eu, fa, fi, fil, fr, gl, gu, ha, he, hi, hr, hu, hy, id, is, it, ja, jv, ka, ki, kk, kn, ko, ky, lg, lt, lv, mk, ml, mn, mr, ms, my, ne, nl, no, nso, pa, pl, pt, rn, ro, ru, rw, sd, sk, sl, sq, ss, st, su, sv, sw, ta, te, tg, th, tn, tr, ts, ug, uk, ur, uz, ve, vi, war, wo, yo, yue, zh, zu

voice_cloning_strength integer

How closely the dubbed voices match the original speakers, from 0 to 10. Higher keeps more of each speaker's voice and accent; lower sounds more natural in the target language. Default value: 7

keyterms list<string>

Names and terms to get right in the dub, such as brand, product or people's names: they help the speech recognition catch these words and the translation keep them as written. Up to 1,000 terms, each at most 50 characters and 5 words, without the characters < > { } [ ] .

{
  "video_url": "https://v3.fal.media/files/monkey/q1fDPhrpfjfsaRmbhTed4_influencer.mp4",
  "target_language": "es",
  "source_language": "auto",
  "voice_cloning_strength": 7,
  "keyterms": []
}

    "file_size": 4404019
  }
}

Other types#

File#

url string* required

The URL where the file can be downloaded from.

content_type string

The mime type of the file.

file_name string

The name of the file. It will be auto-generated if not provided.
