First, make sure you have reviewed the How to set up your Osmo video.
Open up the Rolla app and select the project that you want to start capturing video for.
From the storyboard, select the scene that you want to capture.
You will then see the Osmo set up guide appear (seen below).
FYI: You can always access the Osmo set up by tapping on the "Help" button in the top right corner of the following screen.
Hit "Continue".
You will then be prompted to turn your phone into landscape mode. You can do that by double tapping the (M) button. Once this happens, your phone will rotate 90 degrees and automatically open up the camera.
