There is nothing like CapCut for Linux. There's Resolve, LightWorks, Shotcut, Kdenlive and the less evolved, Openshot. That's it, all the other editors found online or suggested here are nowhere near completion. Also, none of them have the feel of Capcut with its AI and advanced automatic features. If you want to go open source, I'd suggest you learn to use kdenlive. It's good enough with manual workarounds, as long as you don't shoot in 10bit or in RAW or need complex color grading. If you really require automatic AI stuff like in Capcut, stay with Windows/Mac or a tablet. That's the reality.
