After installation, go to Window - AEJuice GIF.jsxbin (on the bottom). Open a composition, press Render in the script. It will export a GIF animation and open it after a render.
You should be good to go with default settings but in case you'd like to customize here are a few settings I change:
Export folder - by default, it's your project's folder but you can export all GIFs to a custom folder.
Loop - by default, all GIFs loop forever but you can loop it once, twice, etc.
Alpha channel - by default, it's off but sometimes you might need a transparent background.
Comps\Folders - sometimes you might need to export a lot of compositions at once so you might need to switch to the folder from compositions.
Change width - this one is rarer but I use it sometimes. It will change all auto-resize to the specified one.
There are a lot of advanced settings but I never use them.
Actually, you can now! We've developed a free script for After Effects that exports GIFs in 1 click. It's called AEJuice GIF. You can download it and learn more at this blog post https://aejuice.com/blog/how-to-make-a-gif-in-after-effects/?utm_source=adoveuservoice_comment
