There are only two video editors on Linux that I would recommend.
1. Blender.
Rock solid. Bespoke UI, but many good tutorials on YouTube. For instance, this
playlist. I have edited dozens of videos with Blender.
2. Olive.
I haven't worked with it, but unfa uses it as his main editor. It seems to be a very promising project. According to unfa, it does crash from time to time, but not too much. Definitely, not on the OpenShot level. So, should be safe.
The rest I was never able to use. I hear relatively good things about KDEnlive, but it never worked for me. Openshot 2 I consider almost a literal open source scam ("award winning" software where I am yet to be able to even import a video without it either crashing or freezing, tested on 4 different laptops, across three versions of Ubuntu).
I am surprised to see several people mention Shotcut. Last time I tried it was either 2017 or 2018 - and it was unusable. After all, it is the UI over the same library that Openshot 1 used. But hey - maybe it improved.
