I'd love to have a video to share with this but I haven't finished any yet.
After Effects is awesome! And it's also clearly what I should have been using for, like, most of my video editing, because my videos are pretty special effects heavy and that's super clunky in Premiere after a while.
It feels like this is the program I can use to just doodle in video making the way I do in Photoshop. In fact, since you can import a Photoshop file as a sequence and animate all the layers independently, I can just make myself a Photoshop file with all the assets for a scene I want to build and import it!
So far I've been trying to build video of the graphs I see in my head when I try to explain complex ideas. Those will be forthcoming.
