In the fast-paced world of social media, where users flit between posts and videos, speed and quality are of the essence. Video platforms like TikTok and Instagram have mastered this art, ensuring that videos load swiftly and maintain crisp quality, regardless of a user’s network speed. But how exactly do they do this?
