# 🎬 AI Short Video Generator

Upload photos of characters, describe a scene, and receive a **1080×1920 (1K) Shorts-ready video** complete with animation, dialogue, voice-over, subtitles, and visual effects.

## Pipeline

```
Images → Claude Vision (character extraction)
       → Claude (script + storyboard)
       → AnimateDiff + Stable Diffusion (animated frames)
       → Coqui TTS (voice lines)
       → FFmpeg (subtitles, FX, assembly)
       → Final MP4 (1080×1920 @ 30fps)
```

## Setup (HuggingFace Spaces)

1. **Fork / duplicate** this Space.
2. Go to **Settings → Secrets** and add:
   - `ANTHROPIC_API_KEY` — your Anthropic API key ([get one here](https://console.anthropic.com/))
3. Choose **GPU T4 small** (or larger) hardware for reasonable speed.
4. The Space will install all dependencies and launch automatically.

## Local Setup

```bash
# 1. Clone
git clone https://huggingface.co/spaces/<your-username>/ai-short-video-generator
cd ai-short-video-generator

# 2. Install system deps (Ubuntu/Debian)
sudo apt-get install -y ffmpeg espeak-ng

# 3. Python deps
pip install -r requirements.txt

# 4. Set API key
export ANTHROPIC_API_KEY=sk-ant-...

# 5. Run
python app.py
```

## Output Specs

| Property | Value |
|---|---|
| Resolution | 1080 × 1920 px |
| Aspect ratio | 9:16 (Shorts / Reels / TikTok) |
| Frame rate | 30 fps |
| Video codec | H.264 |
| Audio codec | AAC |
| Duration | ~30–60 s |

## Visual FX Supported

- **zoom** — Ken Burns zoom-in
- **glitch** — RGB channel-split glitch
- **slow-motion** — frame doubling
- **vignette** — cinematic edge darkening
- Combinations (e.g. `glitch, zoom`)

## Notes

- First run downloads ~4–6 GB of model weights (SD 1.5 + AnimateDiff adapter). They are cached automatically.
- Generation takes ~3–8 minutes on a T4 GPU depending on scene count.
- The `ANTHROPIC_API_KEY` secret is never exposed to users.
