Create a 3D video/animation for a presentation

I need to create a 3D video/animation for a presentation. I'm currently designing models with Blender and seems pretty easy to use.

Anyway I'd like to let the argue following the animation just like a powerpoint presentation (I click a key -> the animation unrolls a开发者_Go百科 little, I click the back/leftarrow key -> the animation rewinds rapidly, I press space -> the animation stops while some elements still hang around)

I already did this with blender animations and C# to control videos, but I'd like to know whether there are other (potentially better) options to achieve this (like: exporting from blender to XAML and then using WPF.. really heavy though). Otherwise I'll stick with what I've already done

My temporary solution is: using blender for both animation and modeling. There are great tutorials out there
