As part of the Hyper Island program we were assigned to redesign a common mobile app experience. The brief was very open to interpretation, and what kind of experience it would be was totally free. The entire process is documented very thoroughly in this Medium article.
As part of a 3 person team, I was assigned to making final animations and a case video, in conjunction with helping with making lo-fi design mockups. We had approximately 3 weeks of time to create the final product.
The animations to the mockups were made completely in After Effects, combined with the PSD files given to me by the designer. The final video was made with both After Effects and Premiere Pro.
