// I renamed methods for a serialization example.
// In this example, there's a "Unicorn" class that knows how to doA and doB,

# Still undocumented here https://developer.apple.com/support/app-previews/
# or here https://developer.apple.com/library/content/documentation/LanguagesUtilities/Conceptual/iTunesConnect_Guide/Chapters/Properties.html
# but iPhoneX App Previews required size is 886x1920
# Unfortunately, iMovie seems to be dumb and creates a 750x1334 App Preview video from your iPhoneX capture
# -- and with black margins on the side
# So you need to crop & scale the video up before you submit it to iTunesConnect:
ffmpeg -i iPhoneX-iMovie.mp4 -filter:v "crop=616:1334:68:0" -c:a copy cropped.mp4
ffmpeg -i cropped.mp4 -vf scale=886:1920 -c:a copy iPhoneX-final.mp4
