I turned an illustrated poster I made into an animated GIF for FB. Illustrations were made using Illustrator. Layers were imported into After Effects to create the animation. Then I used a plugin to export as an animated GIF. Tweaking the export options allowed me to turn a normally large file into just 2.2 MB—perfect for sharing. The downside to such a small file size on a moderately complex animated GIF like this is that the resolution is a little lower than ideal. The upside is that you can tell a little bit more of a story.
I just made my first animation using Photoshop and After Effects. I have some learning to do about creating the right size/resolution for the intended media host, but I think I'm off to a good start. And, I really like making these little stories. It reminds me of when I took video classes at Cornish College of the Arts. One of my favorite parts was adding the music and sound effects. Super fun!
