🤔 Frequently Asked Questions

Where do I start?

Answer: If you're implementing, go to Quick Start Guide. If you're learning, start with Quick Summary.

How long does implementation take?

Answer: Basic MVP takes 2-3 hours. Full feature with all algorithms takes 1-2 weeks.

Do I need machine learning?

Answer: No! The design specifically avoids ML for simplicity and lightweight operation.

Will this work with 100,000 videos?

Answer: Yes, with proper database indexes (included in design). See performance section in Complete Design.

Can I customize the algorithms?

Answer: Absolutely! See Implementation Examples for how to add new algorithms.

Is this production-ready?

Answer: The design is production-ready. Implementation quality depends on following the guides.
