## Overview

VideoDB makes video dubbing incredibly simple with AI-powered translation and voice synthesis. With just **one function call**, you can dub your videos into multiple languages while preserving the original speaking style and timing.

No need for complex audio editing, timeline manipulation, or third-party tools. VideoDB's `coll.dub_video()` handles everything automatically.

## Prerequisites

<Note>
  Ensure you have VideoDB installed in your environment and an API key from [VideoDB Console](https://console.videodb.io). The first 50 uploads are free with no credit card required!
</Note>

```bash theme={null}
!pip install videodb
```

## Connect to VideoDB

Connect to VideoDB using your API key:

<CodeGroup>
  ```python Python theme={null}
  import videodb

  # Connect to VideoDB
  api_key = "your_api_key"
  conn = videodb.connect(api_key=api_key)
  coll = conn.get_collection()
  ```

  ```javascript Node.js theme={null}
  import { connect } from 'videodb';

  const conn = await connect({ apiKey: process.env.VIDEO_DB_API_KEY });
  const coll = await conn.getCollection();

  console.log("Connected to VideoDB");
  ```
</CodeGroup>

## Upload Your Video

Upload the video you want to dub. For this example, we'll use an English video:

<CodeGroup>
  ```python Python theme={null}
  # Upload the original video (English)
  video_url = "https://www.youtube.com/watch?v=0e3GPea1Tyg"
  video = coll.upload(url=video_url)

  print(f"Video uploaded: {video.id}")
  ```

  ```javascript Node.js theme={null}
  // Upload the original video (English)
  const videoUrl = "https://www.youtube.com/watch?v=0e3GPea1Tyg";
  const video = await coll.uploadURL({ url: videoUrl });

  console.log(`Video uploaded: ${video.id}`);
  ```
</CodeGroup>

### Preview the Original

```python Python theme={null}
video.play()
```

## Dub Your Video

<Tip>
  Here's where the magic happens! Dub your video into any supported language with a single function call:
</Tip>

<CodeGroup>
  ```python Python theme={null}
  # Dub the video into Hindi
  dubbed_video = coll.dub_video(
      video_id=video.id,
      language_code="hi"  # Hindi
  )

  print(f"Video dubbed successfully: {dubbed_video.id}")
  ```

  ```javascript Node.js theme={null}
  // Dub the video into Hindi
  const dubbedVideo = await coll.dubVideo(
      video.id,
      "hi"  // Hindi
  );

  console.log(`Video dubbed successfully: ${dubbedVideo.id}`);
  ```
</CodeGroup>

That's it! VideoDB automatically dubbed your video.

## View the Dubbed Video

Generate and play your dubbed video:

```python Python theme={null}
dubbed_video.play()
```

## Supported Languages

VideoDB supports dubbing into many languages. Simply change the `language_code` parameter:

| Column 1   | Column 2 | Column 3             | Column 4 |
| ---------- | -------- | -------------------- | -------- |
| Language   | Code     | Language             | Code     |
| Spanish    | `es`     | Japanese             | `ja`     |
| French     | `fr`     | Korean               | `ko`     |
| German     | `de`     | Chinese (Simplified) | `zh`     |
| Italian    | `it`     | Arabic               | `ar`     |
| Portuguese | `pt`     | Russian              | `ru`     |
| Hindi      | `hi`     | … and more!          |          |

### Example: Dub into Spanish

```python Python theme={null}
# Dub the same video into Spanish
spanish_dubbed = coll.dub_video(
    video_id=video.id,
    language_code="es"  # Spanish
)

print(f"Spanish version created: {spanish_dubbed.id}")

# Play the Spanish version
spanish_dubbed.play()
```
