Anyone here experienced with putting together video trailers and video editing? Or if anyone knows a good place to ask this question I'll appreciate it.

I want to create a trailer for my product (a framework for developers and designers) that will feature some info-graphics style animations, some footage of my product being used in live cases (games), etc. So I want to do some keyframe/storyboarded animations such as translating images with easing etc. And I want to do some nice transitions and text effects, and do things like recording my screen and rendering it on a surface in an image (e.g. a iPad lying on a table).

What tools do you recommend for this? I'm looking for something intuitive and easy to use - I'm not really an animator but I've used tools like expression blend and Unity to do keyframe animations before.
