I've used a few open source video editors and the only one that was stable enough was Kdenlive. Since then I switched to the DaVinci Resolve and am super happy with it, even bought the paid version USB dongle. Funny that Resolve is also not stable on computers that aren't beefy, had to upgrade the PC for it to handle 4k smoothly. It's refreshing that you can de-noise audio, fine-tune video stabilization, color correct and add nice effects and transitions all in one app. I've got a ton of crispy artisan 4k home video now :-)
I also use kdenlive quite extensively and while I get a crash here and there, KDE asks me to restart the app and it then loads the file with the last edits. I don't think I've ever lost edits.
I've done about 25 hours of 4k so far and it's actually not that bad (i7 4770k/16gb ram/ssd).
I don't do much with either, but I've been trying to edit a 3+hr video for a long time and Kdenlive does seem to autosave in ways (or frequency) that OpenShot lacked when I tried it. OS crashed more and I would have to start over more.
I would love to try Resolve but got stuck on installation. They've never packaged it for any distro I can find, and their self-made installer seems to only work on RedHat. Am I missing something? How did you get it installed?
Sadly can't help since I'm using Windows at home, didn't have any installation issues. Only gotcha so far is that one has to download a separate binary for the paid version of the app, there's no "activation" in the free version.
