✨ What is Cyber‑Dome AI Video Generator?

Cyber‑Dome AI Video Generator is an open‑source tool that lets you create stunning videos using artificial intelligence – no expensive software or cloud fees. You run it entirely on your own computer. This guide will walk you through every single step, even if you’ve never used Python or a code editor before.

🔗 GitHub repository: Cyber-Dome/Cyber-Dome-ai-video-generator (⭐ star it if you find it useful!)

🛠️ What you need before starting

• 💻 A Windows, macOS, or Linux computer (4GB+ RAM recommended)
• 🌐 Stable internet connection (for downloading Python and dependencies)
• 📁 About 2–3 GB free disk space
• 🧠 Patience – we’ll go slow, step by step

🐍 Step 1: Install Python (the engine behind the tool)

Why? The AI video generator is written in Python – you need Python to run it.

1. Go to the official Python website: python.org/downloads
2. Download the latest Python 3.10 or 3.11 (avoid 3.12+ for now – some libraries may not be ready).
3. Windows users: During installation, check the box that says “Add Python to PATH” – this is CRUCIAL. Then click “Install Now”.
   macOS/Linux: Run the installer or use your package manager (e.g., brew install python@3.11).
4. After installation, verify it worked:
   • Press Win + R → type cmd (Windows) or open Terminal (Mac/Linux).
   • Type python --version and press Enter. You should see something like Python 3.11.x.

✅ Troubleshooting tip: If python --version doesn't work, try python3 --version. On Windows, you can also re‑run the installer and select “Modify” → tick “pip” and “Add to environment variables”.

📝 Step 2: Install a Code Editor (Visual Studio Code)

You can run the tool from the terminal, but a code editor makes everything easier – we recommend VS Code (free).

1. Download VS Code from code.visualstudio.com
2. Install it with default options (on Windows, tick “Add to PATH” during setup).
3. Once installed, launch VS Code and install the Python extension:
   • Click the “Extensions” icon (or press Ctrl+Shift+X)
   • Search for “Python” by Microsoft → Install.

🟢 Alternative: If you prefer a simpler editor, you can use Notepad++ (Windows) or any text editor – but VS Code is highly recommended.

📦 Step 3: Get the Cyber‑Dome AI Video Generator code

You have two easy options:

• Option A (easiest): Download ZIP from GitHub
  • Go to the repo
  • Click the green “Code” button → “Download ZIP”
  • Extract the ZIP file to a folder on your desktop (e.g., Cyber-Dome-ai-video-generator-main)
• Option B (for Git users): Clone the repository

  git clone https://github.com/Cyber-Dome/Cyber-Dome-ai-video-generator.git

📁 Remember the folder location – we’ll call it project folder from now on.

📂 Step 4: Open the project in VS Code

1. Launch VS Code
2. Click File → Open Folder… and select the project folder you extracted.
3. In VS Code, open a terminal: Terminal → New Terminal (or press Ctrl + `)

You should see a terminal panel at the bottom. This is where we’ll type all commands.

🌍 Step 5: Create a virtual environment (keeps things clean)

This step is optional but prevents conflicts with other Python projects. Type these commands in the VS Code terminal one by one:

# Windows
python -m venv venv
venv\Scripts\activate

# macOS / Linux
python3 -m venv venv
source venv/bin/activate

After activation, you’ll see (venv) appear at the beginning of your terminal line – that means it’s working.

📥 Step 6: Install required packages

The project needs additional Python libraries. The creator usually lists them in a requirements.txt file. Run:

pip install -r requirements.txt

If there is no requirements.txt (check the project folder), install the typical AI video dependencies manually:

pip install opencv-python torch torchvision moviepy pillow numpy

⏳ This may take a few minutes – it’s downloading AI models and libraries.

🎬 Step 7: Launch the AI Video Generator

Look for the main Python file – it’s often named main.py, app.py, or generate_video.py. In the terminal, type:

python main.py

(Replace main.py with the actual filename if different.)

If everything is correct, you’ll see a graphical user interface (GUI) or command‑line prompts. Congratulations – you’re running the AI video tool!

🖼️ Step 8: Using the interface – screenshot walkthrough

Below are real screenshots from the project. Follow them to generate your first video.

📸 Main dashboard – select video style and length.

📸 Enter your prompt or script – the AI will generate matching visuals.

📸 Real‑time progress bar – generation takes 1–3 minutes depending on your hardware.

📸 Preview the generated video before saving.

📸 Export your video in MP4 format – ready to upload to YouTube or social media.

💡 Pro tip: For better results, use clear, descriptive prompts (e.g., “a futuristic city with flying cars at sunset”).

⚠️ Common issues and fixes

• “Python is not recognized” → You missed the “Add to PATH” step. Re‑install Python and tick that box.
• pip command not found → Install pip manually or re‑run Python installer with “pip” selected.
• ModuleNotFoundError: No module named 'cv2' → Run pip install opencv-python again.
• Out of memory / slow generation → Close other programs. If you have a GPU, make sure PyTorch detects it (pip install torch torchvision --index-url https://download.pytorch.org/whl/cu118 for CUDA).
