## ✅ Option 2: Local Generation (Free but Slow)

### When to Use:
- You have a powerful GPU (RTX 3060+)

- You need complete privacy

### Setup:

# Open index_local.html
open index_local.html
```

### Pros:
- ✅ Completely free
- ✅ No API keys needed
- ✅ Works offline
- ✅ Private

### Cons:
- ❌ Very slow on CPU (5-10 minutes per video)
- ❌ Requires 5GB download

## ✅ Option 3: Alternative Free APIs

### RunPod, Banana, or Modal:
These are alternatives to Replicate with similar pricing/features.

### Stability AI:
If you want Stable Video Diffusion specifically.
