A good alternative to AE, especially for simpler stuff, is Apple Motion. It works in real time, unlike AE.
I’ve chosen it over AE for all the animated titles I’ve worked on for the past 8 or so years and have had no issues.
Opening AE to update old projects is a chore, never enjoyable. Motion is actually fun to use. I paid once, and they’ve been updating it for free since 2011.
How can I install that on Ubuntu? And I don't need a replacement for "simpler stuff". I appreciate the attempt but my point is there's nothing comparable at a pro level. If I had the ability to use creative cloud (which Mac does), I would of course use that.
So essentially, you can't. That's the whole point.
Send me a guide for the latest versions of creative cloud working with wine please. It'd be great to be proven wrong and gain 100% usefulness in Linux land :)
but also by today there are a lot of good alternatives many more and much more mature ones then in the past
