Check if the license allows for commercial use (advertising, products) or if it is restricted to personal/educational use (like many free sites).

Ensure you select 1080p (Full HD) or 4K depending on your project needs.

Purchasing HD and 4K video clips is primarily done through stock footage platforms, which offer vast libraries for commercial, social media, and personal projects. The best options often depend on whether you need a subscription for many clips or a one-time purchase.
