A pretty hot little video.
This wasn’t done with AE’s 3D text animation. I’m thinking that they are precomps of single words that use an animated mask for reveal, an animated anchor point to control the flopping and unfolding and, finally, a light with shadows for the responsive drops.
If you’re new to AE, this would be a good one to get started on. A lot of basic principals crammed into a tiny animation.
Good luck, thanks for sharing the video!
