Girl, we got you! We actually wrote a whole blog post about it here. But the super short version is take a short video (or make a video out of a set of photos) and convert it online to a .gif file using a site like ezgif.com!
I usually go back to my spreadsheet where I list all the templates by functionality! We also wrote this post to help you find the right template. If you have a design example and want to know what template to use feel free to send it to us at email@example.com and we will let you know and post it below!
