Be prepared to pay up to get the full experience. You can create 15-second "best of" clips for free, but you'll need to spring for the premium version of the feature in-app if you want to unlock its full potential. And of course, you'll need a Parrot drone (a Bebop 1, 2 or Power) for this to work -- you can get similar apps from the likes of GoPro, but it won't be the exact same experience. If you have the hardware and regularly record aerial videos, though, this could let you spend more time flying and less time trimming clips.
