# AI Video Transcriber & Translator

This tool extracts audio from videos, transcribes it using OpenAI's Whisper model, and translates the transcript using Google's Gemini API.

## Setup

1.  **Install Dependencies:**
    ```bash
    pip install -r requirements.txt
    ```
    *Note: You need `ffmpeg` installed on your system.*

2.  **API Key:**
    Set your Gemini API key as an environment variable:
    ```bash
    export GEMINI_API_KEY="your_api_key_here"
    ```

## Usage

### Linux / Mac
Run the wizard script:
```bash
./run_v2.py
```

### Windows
1.  **Install FFmpeg:** Download from [ffmpeg.org](https://ffmpeg.org/download.html) and add the `bin` folder to your System PATH.
2.  **Run:** Double-click `run_v2.bat`.
    *   It will automatically create the virtual environment, install dependencies, and launch the tool.

### Manual CLI
```bash
python ai_transcriber_v2/main.py <path_to_video> [options]
```

### Options:
*   `--model`: Whisper model size (`tiny`, `base`, `small`, `medium`, `large`). Default: `base`.
*   `--lang`: Target language for translation. Default: `English`.
*   `--force`: Overwrite existing transcript/translation files.

### Examples:

**Single File:**
```bash
python main.py ../my_video.mp4
```

**Entire Directory (Recursive):**
```bash
python main.py ../videos_folder/ --lang "Spanish" --model small
```
