Well. I am not sure how you want to work like. And what you want to do. I recommend checking out After Effects since from there you can export the finished project to a GIF - i am not sure if you need to install the plugin for it nowadays though. If you want to learn basics in AE I recommend this collection of tutorials. Most of the hyperlinks will lead to Youtube or the official Adobe Tutorial Section. https://www.creativebloq.com/after-e...orials-1232661
I once had a Pastebin with some "books". But I sadly can't find it anymore. If I get it by any chance back - I'll edit this post or reply again.
