Hello @Fox_9514 and welcome to the forum!
Yes, Krita has issues there. BUT →
There is a way to render Animations as well as Time Lapse recordings!
BUT it needs a little computer knowledge.
Furthermore, it would be good when you don’t fear for things like a computer terminal or a command line, but it is feasible for everyone who really wants this, is willing to search up missing information on the internet in cases when something does not work right from the start.
So if you don’t fear to fiddle around a little bit, are able to follow written instructions and have the ability to anticipate things, search the web if needed, then you should begin to read that topic up. → Basic Space Exercises Timelapse
In my eyes, it is described in a way that should allow those of us willing to learn and not to give up, to set up and use FFmpeg on Android for making Time Lapse and animation videos in the way that user described it.
The other options you have are to render your videos later on a PC with Krita, or you search for a video editing software that is able to stitch a video together using a series of pictures. Both options work and were used in the past from other users.
