In this demo we were guiding the user through the video editing capabilities of the device (a small tablet in this case). One of the challenges I ran into here was being tasked with recreating a landscape-only app in a portrait-oriented experience, while retaining as much of the original feel as possible. Here again I relied on device screenshots, slicing and rebuilding the UI to fit into a portrait orientation, small info popups, and embedded stock videos as sample clips for the user to play with.
Constraints such as this (set orientations or permanent top/bottom bars) were common client requests and required a healthy dose of creative problem-solving to design around.
