In the past, I have been a fan of video editors such as Kdenlive, Kino and to a more advanced extent, Cinelerra. But to be totally honest, all of them leave something to be desired for various reasons. Kdenlive would be good, if it was not KDE based and not so easy to crash on non-KDE desktops. This led me to falling in love with a new option still under heavy development known as OpenShot.
Where other editors are either terrible to use or so buggy that they can not seriously be relied on, I found OpenShot to be something that I have come to rely on. It’s still under heavy development, but with the recent release of transitions/effects, the editor is quite usable even this early in its life.
Does this mean that you are ready to go an create Hollywood movies with it? No, of course not. But I would say that for most people, it is a great option. And having used them all, I will be looking to rely on it as much as possible.
