## Quick Start
```bash
# 1. Install dependencies
pip install -r requirements.txt

# 2. Test the pipeline (no video or API needed)
python simulate_and_test.py
python component2_feature_extractor.py

# 3. Run on a real video
python component1_candidate_generator.py your_video.mp4
python component2_feature_extractor.py
```
