How to animate transitions between scenes?

Hi everyone, I am building game w$$anonymous$$ch could benefit from small transitions with animation at the completion of the level. Similar to the animations that take place during Infinity Blade's fights. Im really good animating in c4d and Ive been using Itween to animate simple camera movements and actions inside Unity. How should I create t$$anonymous$$s? Should I animate my character and place the animation in my screen on unity? I want the scene to look the exact same and im sure I don't have to recreate the scene in c4d in order to create the animation in a completely externals software. Im a little confused about the workflow here. Thanks in advance!
