If templates aren't your thing or you want something more unique, you can create a Video Design from scratch.
1) To start, tap on 'New Design' from the top section of the welcome screen. If you are in 'my designs' you can tap on the '+' icon.
2) Select your desired video size and tap next. If you are not sure what video size to choose read the 'What Video Size to choose?' section.
3) When you tap next, you will be taken to a blank white edit screen. Here you can add your elements by tapping the '+' icon.
