There are a TON of timelapses coming out from the past eclipse and a lot of them from Smart Telescopes like the Seestar. I only caught a partial eclipse but my timelapse had a lot of jitter and the video didn't look great overall.
Luckily the individualf rames within the timelapse can be wrangled using PIPP OR Siril. I show you how to use both to get a much better, jitter free, very stable, timelapse.
As mentioned in the video, this is not a catch-all fix. I have not tested this with a total eclipse so I'm sure there are things to consider there. But hopefully the video give you an idea of how to deal with this kind of an issue.
