You may notice: (there's an App for that!)
This was filmed on a windy day - yet there's very little wind noise from the microphone.

This was hand-held (no tripod) - yet it's not your typical shaky phone video
Exposure and focus don't shift during the shots - even through changing views
There are a variety of shots and professional animated subtitles. All editing done on iPhone.
