Shotcut: Free, open source, cross-platform video editor
Shotcut (on Linux at least) just doesn't work.<p>I've used pretty much all amateur video-making software for Windows and some for Mac, Screenflow, FinalCut Pro, etc.<p>The best by far is FinalCut Pro (Mac-only), because it automatically creates proxy files and allows you to edit everything in real time with no lag, even when adding complicated effects.<p>The situation on Linux is dismal. The only good one is <a href="https://kdenlive.org/" rel="nofollow">https://kdenlive.org/</a>. It's actually I'd say at par to FinalCut in terms of performance, although the UI could use some clean up. It's the one I use because the other ones would either keep crashing, or be impossibly slow.
