I think it documents nicely what the Xaelander software suite is capable off. It demonstrates animating a walk cycle on the primary character and animating the secondary character. The powerful two point 3D camera tracking and animating a special effect by capturing motion onto a locator.
I look at the short video and think “Even if I captured every part ten times, I created that animation in about 20 minutes. An experienced storyboard artist could probably come close nailing that shot in 20 minutes. But a previz animator should never ever have to just float his characters around anymore – they should make them walk around.”
