When I began working at Tubatomic, we we're tasked with creating new videos from scratch. That included hiring actors, filming against a green screen, recording and mixing audio, and creating animations that visually described the dialogue. You can view the finished product here. See the Well and Wise videos at the bottom of the page. I was responsible for creating the majority of these animations, mixing down the audio, and selecting music for the videos.
Aside from the ChannelBlue site, I also designed a mini-site for an email campaign. Check it out.
