An app that allows animating graphics, sketches and video layers with templates?

[FrenchTV]

Is there an app that allows one to animate images, sketches and videos as well as provide templates and models, objects to create characters?

I have written a talk show and want to present it using collage cut outs, videos and sketches, i imagine with all the apps available on the iphone and ipad that something must be out there, i have soe that allow you to create characters while other apps i tried can super impose mustaches, clothing and even shoot while keying a color or two.

at the moment i am using after effects on a imac i7 but wondering what i dont know about on the ipad
i figure it cant hurt to ask
