I use ipisoft in most of my animations. Here’s a link to a movie I created last year and should have submitted to this competition because most of the animation was done using ipisoft (about 90 %).
Of course I used key-framed animation in addition to my motion captures. As you look at the main character (Lego pirate character), the motions on the raft are key-frame animation. But when he reaches the island, all of his remaining animation are based on ipisoft motion captures. Most of the other character animations were ipisoft captures as well...
