Here is a product that I'm extremely ... ahem... passionate about. I found Passion Planner my freshman year when I was learning to manage my time on my own. I loved the creativity in the design and the ability to include details in your schedule.
During my pre-production period, I went to a Passion Planner tips and tricks Facebook group and asked members what their planner means to them. Many of their responses are included in the promo. Some posted their decorations and inspirational quotes.
One of the most challenging things about this project was matching the camera movements. Often after setting a keyframe, I would realize that a bezier curve was set between two keyframes of the same value. Also, timing each individual composition brought it's own set of problems after the camera movements would be set, and edits to a comp would be needed.
