Compressing video recorded on a cellphone allows you to record dozens or hundreds of hours of footage, whereas uncompressed or minimally compressed formats - like AVI - would only allow for a couple of hours of footage before your device’s storage was completely full. All newer Apple devices like the iPhone and iPad use HEVC to record video, and some Android devices, like the Pixel phones from Google, do as well. More cellphone manufacturers are adding support for HEVC, too.

It is useful for other things besides streaming services, though. HEVC is a compression algorithm - it takes large, uncompressed (or minimally compressed) video files and makes them much smaller with only a slight decrease in quality.Ĭompressing video files enables streaming services like Netflix or Hulu to send you video without completely bogging down your internet connection or blowing through your data cap.
