## 1. Installation

### Option 1: Install via ComfyUI Manager
Open ComfyUI Manager and install the **ComfyUI Stable Video Diffusion** (author: **thecooltechguy**) custom node.

### Option 2: Install manually
```
cd ComfyUI/custom_nodes/
git clone https://github.com/thecooltechguy/ComfyUI-Stable-Video-Diffusion
cd ComfyUI-Stable-Video-Diffusion/
python install.py
```

### 2. Download models into `ComfyUI/models/svd/`

## Node types
- **SVDModelLoader**
    - Loads the Stable Video Diffusion model
- **SVDSampler**
    - Runs the sampling process for an input image, using the model, and outputs a latent
- **SVDDecoder**
    - Decodes the sampled latent into a series of image frames
- **SVDSimpleImg2Vid**
    - Combines the above 3 nodes above into a single node
