at my 9-5, we use final cut for heavy editing, aftereffects for light editing and motion graphics/special effects.
I did all the character animation here with after effects and motion (which is a special effects add on for final cut). Simple stuff but it was a fun project.

And then my first forray into editing and voicover and real motion design are for these sonic videos. Blame the crappy design choices on the client, but you can get an idea of what is possible only using aftereffects.
