Shot and edited on an iPhone 4 with iMovie for iPhone. Started with several HD clips, all 20 seconds long, then used iMovie to order and trim them, adjust transitions, and add titles. Used the “Modern” theme in iMovie for iPhone, which included a specific transition, song, and title font. To retain full video quality, I exported as HD from iMovie to the iPhone Camera Roll, synced it to my Mac via iPhoto, and finally uploaded it to YouTube.
