Several decent video editors are available on the Linux platform. Kdenlive, OpenShot, Cinelerra and Pitivi are those that come to mind as “big players” in an admittedly small market. I’ve used them all through the years, with varying levels of success. A frustration of mine is that invariably, I end up using a proprietary video editing suite like iMovie or Final Cut Pro when I have to do a larger project. As an open-source enthusiast, that doesn’t settle well with me.
