Automated Video Generator

This project creates marketing videos by combining OpenAI for script and image generation with ElevenLabs for speech synthesis. Images and audio are assembled into a final MP4 using MoviePy and FFmpeg.

Requirements

• Node.js 18 or newer
• Python 3.8 or newer
• FFmpeg installed and available in your PATH

Installation

1. Install Node dependencies:

   npm install

2. Create a Python virtual environment and install packages:

   python3 -m venv venv
   source venv/bin/activate  # On Windows use `venv\Scripts\activate`
   pip install -r requirements.txt

3. Copy .env.example to .env and provide your API keys.

Environment variables

• OPENAI_API_KEY – OpenAI API key used for text and image generation.
• ELEVENLABS_API_KEY – ElevenLabs API key for text‑to‑speech.
• BASE_URL – Base URL where the app is served (e.g. http://localhost:3000).

Running the development server

Start the Next.js dev server:

npm run dev

Then open http://localhost:3000 in your browser.

Generating videos

1. Use the web interface to generate voice‑over scripts from a marketing prompt.
2. Upload an image to create styled variations via DALL·E.
3. Select the desired voice and images, then click Generate Video. The resulting MP4 files are saved under public/output.
