## 🚀 Quick Start (Choose One)

### Option A: Deploy to Hugging Face (5 minutes)

**Easiest option - No local setup needed!**

1. Go to [huggingface.co/spaces](https://huggingface.co/spaces)
2. Create new Space (Gradio SDK)
3. Upload all files from this folder
4. Wait 5-10 minutes for build
5. Done! Your app is live 🎉

**👉 See `QUICK_START.md` for detailed steps**

---

### Option B: Run Locally (10 minutes)

**Full control - Run on your computer**

```bash
# 1. Install FFmpeg
choco install ffmpeg  # Windows
brew install ffmpeg   # Mac
apt install ffmpeg    # Linux

# 2. Setup Python
python -m venv venv
source venv/bin/activate  # or venv\Scripts\activate on Windows
pip install -r requirements.txt

# 3. Run!
python app.py
```

Then open: http://127.0.0.1:7860

**👉 See `LOCAL_TESTING.md` for detailed steps**

---

## 📖 Documentation Guide

**New to the project?**
1. Start with `QUICK_START.md` (5-min read)
2. Then `README.md` for full features

**Want to test locally?**
→ `LOCAL_TESTING.md`

**Ready to deploy?**
→ `DEPLOYMENT.md`

**Need technical details?**
→ `PROJECT_SUMMARY.md`

---

## 🎯 First Steps After Setup

### Test with a Sample

1. **Find a short audio file** (1-2 minutes)
   - Or use a YouTube URL

2. **Run the app**
   - Upload the file
   - Select "Small" model
   - Click "Generate Transcription"

3. **Download results**
   - Try the SRT file first
   - Open in a text editor

**Example YouTube URL to test:**
```
https://www.youtube.com/watch?v=dQw4w9WgXcQ
```

---

## ⚙️ Basic Settings

### Model Selection
- **Tiny**: Fastest (use for testing)
- **Small**: Recommended (good balance)
- **Medium**: Best quality (slower)

### Language
- **Auto-detect**: Works great! (recommended)
- **Manual**: Select if you know the language

### Speaker Diarization
- **Off**: Faster (default)
- **On**: Identifies different speakers (requires HF token)

---

## 📊 What to Expect

### Processing Time (10-minute audio)

| Setup | Model | Time |
|-------|-------|------|
| CPU | Tiny | ~1 min |
| CPU | Small | ~3-5 min |
| CPU | Medium | ~8-10 min |
| GPU | Small | ~1 min |

### Output Files

After processing, you get **4 files**:

1. **📄 filename.srt** - Most common, for video players
2. **📄 filename.vtt** - For web players
3. **📄 filename.txt** - Plain text transcript
4. **📄 filename.json** - Full data with word timestamps

---

## 🔌 API Usage (Advanced)

Yes, this has an API! Use it in your code:

```python
from gradio_client import Client

client = Client("YOUR_SPACE_URL")
result = client.predict(
    url_input="https://youtube.com/watch?v=...",
    model_size="small",
    language="auto",
    enable_diarization=False
)
```

---

## 💡 Pro Tips

### For Best Results
- Use high-quality audio (clear speech)
- Choose specific language if known
- Use Medium model for final production

### For Speed
- Use Tiny model for quick tests
- Keep files under 10 minutes
- Disable speaker diarization

### For YouTube
- Some videos may be restricted
- Use direct file upload as fallback
- Works with unlisted videos

---

## 🆘 Common Issues

### "ModuleNotFoundError"
→ Run: `pip install -r requirements.txt`

### "FFmpeg not found"
→ Install FFmpeg (see QUICK_START.md)

### "YouTube download failed"
→ Video may be restricted, try file upload

### "Slow processing"
→ Normal on CPU, use smaller model or GPU
