How to Set Up Your iPhone To Shoot Good Video by iPhoneographers

The iPhoneographers have updated their basic instructional video about adjusting the settings on an iPhone6, from video quality to slomo. How do you shoot 4K or 1080P? Where does the iPhone tell you how big you file sizes will be? How do you set and auto lock focus? How do you transfer footage to another device using AirDrop. NOTE: Some of the settings will only be available on the latest phone (currently the 6s) and running the latest iOS software.
