Cinelerra *had* the most promise and it’s probably good if you want to run a TV station. However, it’s not creative at all. Simple edits are easy. However, anything else can become a stunt. IMO, Kdenlive has seen the quickest growth. Lives is also doing well. In the next few years we may see those apps grow into the free alternative of Finalcut – but not Cinelerra. It does what it does, and there is no need to change.
Crash, crash, crash... when it didn't crash I found it to be in that middle zone of more than a basic editor, but not a professional one... features are not very intuitive. It took me more than 30 minutes of randomly clicking to figure out how to adjust the effects applied to a clip and then I was underwhelmed with the options. To be fair... I was looking for something specific when I tried this out. I've used Adobe and other video editors in the past and this just missed my current needs and my expectations based on past experiences.

This Linux video editing software is an interesting one. Kino is not your typical iMovie-style non-linear video editor. It appears to have been created in order to primarily cut a single video, or maybe a couple of videos to make a home video. It works pretty well but it requires one to use only standard NTSC or PAL formats with their respective framerates and video sizes. All in all, the video editor is stable and easy to use, but very limited.
OpenShot is a cross platform video editor that is “simple and powerful”. It’s built specifically for the YouTube generation or, anyone looking to make simple videos by cutting things together and adding a few effects here and there. By no means is it on the same level as something like Final Cut, or Premiere, or even Kdenlive. Instead, think of OpenShot like Linux’s iMovie.
