Here's a quick overview of how we animated Surfer Girl's Happy Dance video:
We started with some rough sketches, and then used several dancers to come up with some dance steps that would both work for animation and in real life. Then we created some wireframes for the three girl characters, and put them to the music (which was composed by Robi Navicula in Bali). Once we had the timing right, we completed the in-betweening and final animation. Adding colours and compositing is where it starts looking like a real animation, before rendering the final video in HD. The video was for a dance contest which you can view at Surfer Girl's website, and we have shown a sample of some of the dancers.
Overall this was one of the most challenging and enjoyable projects we have done yet!
