### Method 1: Web Upload

1. Go to https://huggingface.co/spaces
2. Click "Create new Space"
3. Choose **Gradio** as SDK
4. Upload all files from this directory
5. Select GPU hardware (T4 minimum, A10G recommended)
6. Space will auto-deploy!

### Method 2: Git Push

```bash
# Create a Space on HuggingFace first, then:
git clone https://huggingface.co/spaces/YOUR_USERNAME/YOUR_SPACE_NAME
cd YOUR_SPACE_NAME

# Copy files
cp -r /path/to/CogVideoXInterp/* .

# Push

## 📝 Usage

1. **Load Model** - Enter model path or use default `feizhengcong/CogvideoX-Interpolation`
2. **Upload Images** - Provide start and end frame
3. **Write Prompt** - Describe the motion/transition
4. **Generate** - Wait 2-5 minutes for video

### Example Prompts

✅ "A person walks forward slowly, their body moving naturally with each step"

✅ "The camera smoothly pans from left to right, revealing the scene"

✅ "A dancer gracefully transitions from one pose to another"

## 🔧 Troubleshooting

### Out of Memory

Reduce parameters in the app:
- Frames: 49 → 25
- Steps: 50 → 30

### Model Download Fails

Check internet connection. Model is ~20GB and downloads to:
- Linux/Mac: `~/.cache/huggingface/`
- Windows: `C:\Users\USERNAME\.cache\huggingface\`

### Import Errors

Make sure all files from this directory are in the same location, especially the `cogvideox_interpolation/` folder.
