Prototype the Still Motion Capture Application

Just as you’ve done in the section “Prototype the Capture Player,” you may want to start by creating a rough sketch of your QTKit still motion capture application. Think, again, of what design elements you want to incorporate into the application. Rather than simply jumping into Interface Builder and doing your prototype there, you may want to visualize the elements first in your rough sketch, as shown in Figure 4-2.

In this design prototype, you can start with three simple objects: a capture view, a QuickTime movie view, and a single button to add frames. These will be the building blocks for your application. You can add more complexity to the design later on. After you’ve sketched out your prototype, think how you’ll be able to hook up the objects in Interface Builder and what code you need in your Xcode project to make this happen.
