Since I started working for a think tank I am often confronted with the problem that my standard set of deliverables are not sufficient to describe a vision. I often need to highlight the context where users interact with the devices. Ideally I should be able to take my wireframes and show them in an animated style with a bit of context where they are used. Like adding a stage or a scenario. Now I am not an animator and I will not become a movie, 3D or animation genius in a short amount of time. But I was wondering if you know of any tools that enables you to take graphic files and turn them into simple animated movies. I am familiar with Adobe CS and Premiere but not Flash.
EDIT: thanks for all the suggestions so far but screen capture software is not what I am looking for since it does only focus on what happens on the screen and not the context in which the user is using the device. The Hype recommendation looks like an interesting option which I am going to check out.
