The lack of open-source animation tools is really concerning to me. I've been looking for a way to animate some text and graphics for a series of training presentations that I was making and I couldn't find anything suitable. Open source tools are either geared towards animation of cartoons or they're so rudimentary that they're not really valuable to invest the time into.

Anyone have any recommendations for animation tools? Something that works either on macOS or Linux? If only paid solutions exist, what's out there (besides After Effects)?
