The labels
480p is standard definition, 720p is HD, 1080p is Full HD and 4K is Ultra HD. HEVC is a newer way of compressing video that keeps the picture sharp at a smaller size.
How the apps choose
Streaming apps adjust the picture to your connection automatically: Data Saver on a phone plan, High or Best on Wi-Fi for Full HD and 4K. Many use HEVC behind the scenes to save your data.
Made for 4K

The orange flag
