I highly recommend you give Shotcut a chance. I am a total beginner with video editing but unlike kdenlive (sorry, still a cool project) it gave me much bigger "professional product" vibes.
IMO it is more polished, built-in effects are better, runs stable on Windows for me (so you can try it anytime before switching to Linux) and it looks nice.
I was editing video gameplay footage with kdenlive some time ago (on Windows) and it was indeed very hard (and also crashed a bunch). In fact i think i switched when i also wanted to overlay text in a certain way (a timer in my case) which seemed to be impossible to make look halfway decent.
Thanks for the suggestion and reminder! I remember trying Shotcut many years ago and it was worse (IMO) than Kdenline at the time.
The good news is I gave it a quick spin just now and it has come a -really- long ways since then. Within 10 minutes I had an ok workflow for doing cuts / ripple deletes. You can add text with individually colored words and styles, add a background shape behind the text and also add effects like drop shadows, glows and other things. All done graphically in the video preview.
It's no where near as intuitive as Camtasia but I think it's very usable and over time I'm sure I'll get used to its features.
I just hope it's stable, I'll edit a couple of videos and see how it goes.
