I've been using After Effects for a while.
And even though I can't control how old I'm getting, over the years I've come up with lots of useful presets and scripts that make complex or repetitive tasks easy to apply. And over on my YouTube channel, I make as many sample projects and assets available to viewers as possible. This is a collection of all of those downloads in one place. Take a look, start downloading, and don't forget to tag me @jakeinmotion to show off what you make!
By the way, all of my downloads are pay-what-you-want, which means you can type in $0 and get it for free, and I'm totally ok with that! I greatly appreciate donations for any downloads you find useful but do not expect them.
