  Let’s go step-by-step.

  Step 1: Understand What You Need

  Before installing anything, make sure you have:

  💻 Basic Requirements:

  • A PC/Laptop (Windows/Linux preferred)

  • GPU (recommended):

    • NVIDIA RTX 3060 or higher

  • At least:

    • 16GB RAM

    • 50–100GB storage

  👉 If you don’t have a GPU → skip to Cloud Method below

• Step 2: Download the Repository

  Go to the tool’s GitHub page:

  • Wan → https://github.com/Wan-Video/Wan2.1

  • Hunyuan → https://github.com/Tencent-Hunyuan/HunyuanVideo

  • CogVideoX → https://github.com/zai-org/CogVideo

  Then:

git clone https://github.com/REPO-LINKcd folder-name

💡 This downloads the full AI tool to your computer.

Step 3: Install Dependencies

Most repos require Python + libraries.

Install Python (if not installed)

• Download from: https://www.python.org

Then install requirements:

pip install -r requirements.txt

Some tools may also need:

pip install torch torchvision

Step 4: Download AI Models

This is the most important step.

Inside the repo, you’ll find instructions like:

• Download model weights (.ckpt / .safetensors)

• Place them in a folder (e.g., /models)

⚠️ Models are BIG (5GB–50GB)

Step 5: Run the Tool

Each repo gives a command like:

python app.py

or

python inference.py

After running:

• You’ll get a local UI (browser link)

• Or command-line generation

Step 6: Generate Your Video

Example prompt:

"A cinematic shot of a futuristic city at sunset, ultra realistic, 4k"

Then the AI will:

• Process frames

• Generate video

• Save output file
