Create an Animation

I need to create 4-5 seconds animation that will show how to use a feature in my mobile application. Details: The animation should be a sequence of images based on screenshots from the current product. There is no need to draw new graphics or images. The only manipulation needed are zooming in / out and applying some tap indication, like the RADOMIR animation that can be found here: [login to view URL] The animation will show how to use a rich text editor. It will present the user flow from clicking the edit button, applying font, selecting color, clicking bold and showing the final result. More detailed scripts will be sent upon request. Attached are some images in different stages of the user flow. The animation should be done in two sizes (in points): 342 * 165 for the iPad 283 * 165 for the iPhone Output: A sequence of png files creating the animation.
