# AI Video Dubber & Translator (`dami_studio/ai-video-dubber`) Actor

Translate and re-voice any video into another language. Transcribes the speech, translates it, generates a new AI voice-over timed to the original, and muxes it back with optional translated subtitles. No voice cloning — clean, consent-free dubbing.

## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## AI Video Dubber & Translator

Takes a video in one language and gives you back the same video speaking another. It transcribes the original speech, translates the text, generates a fresh AI voiceover timed to the original pacing, and muxes that audio back onto the video. Built for creators, localization teams, and anyone who needs a quick second-language cut without booking voice talent.

There is no voice cloning here. The output uses a standard synthetic voice, so you don't need anyone's consent to ship it.

### How it works

The actor runs transcription, then machine translation, then text-to-speech, fitting the new audio to the original segment timings before remuxing. If you turn on subtitles, the translated lines are burned into the frame instead of added as a separate track.

### Input

| Field | Required | Notes |
|---|---|---|
| `videoUrl` | yes | Direct URL to the source video. |
| `targetLanguage` | no | ISO code for the language to dub into (`es`, `fr`, `hi`, `ar`, ...). Defaults to a common target if omitted. |
| `voice` | no | Which AI voice to use for the generated narration. |
| `burnSubtitles` | no | Overlay the translated subtitles onto the video. Off by default. |
| `openaiApiKey` | no | Your own OpenAI key, used for the steps that call an AI model. |

### Output

You get the dubbed video file plus the artifacts produced along the way. The main fields are the dubbed video URL, the source and translated transcripts, and the subtitle file (`.srt`) when subtitles are generated.

### Example

```json
{
  "videoUrl": "https://example.com/clip.mp4",
  "targetLanguage": "es",
  "voice": "alloy",
  "burnSubtitles": true,
  "openaiApiKey": "sk-..."
}
````

### Pricing

$0.12 per dubbed minute, pay per result, no subscription. Bring your own OpenAI key for the steps that use an AI model.

### Notes

The voiceover is fit to the original segment timings, so if the target language is much wordier than the source, the pacing can feel slightly rushed on long segments. Burned subtitles are permanent and can't be toggled off in a player.

# Actor input Schema

## `videoUrl` (type: `string`):

Public direct URL to the source video (.mp4/.mov/.webm). You host it; nothing is scraped.

Language to dub into (ISO-639-1: es, fr, de, hi, ar, pt, ja, zh, …).

## `sourceLanguage` (type: `string`):

Spoken language of the source, or 'auto' to detect.

## `voice` (type: `string`):

AI voice for the dub (OpenAI TTS voices).

## `burnSubtitles` (type: `boolean`):

Overlay the translated subtitles onto the video.

## `openaiApiKey` (type: `string`):

Your OpenAI key — used for transcription (Whisper), translation, and TTS. Kept private.

## `ttsModel` (type: `string`):

OpenAI TTS model: tts-1 (fast) or tts-1-hd (higher quality).

## `translationModel` (type: `string`):

Chat model for translation. Default gpt-4o-mini.

## `baseUrl` (type: `string`):

OpenAI-compatible base URL for all calls. Default https://api.openai.com/v1.

## Actor input object example

```json
{
  "videoUrl": "https://example.com/video.mp4",
  "targetLanguage": "es",
  "sourceLanguage": "auto",
  "voice": "onyx",
  "burnSubtitles": true,
  "ttsModel": "tts-1",

}
```

# Actor output Schema

## `results` (type: `string`):

Result rows / metadata are stored in the default dataset (one row per item).

## `files` (type: `string`):

Generated media/files (video, audio, images, captions) are stored in the default key-value store.

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "videoUrl": "https://example.com/video.mp4"
};

// Run the Actor and wait for it to finish
const run = await client.actor("dami_studio/ai-video-dubber").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});
