After briefly testing all the various open-source video editors I could find easily available for fedora 13, I came to the conclusion that kdenlive was the best fit. By and large most of the editors were plain unusable for more than 5 minutes or just had too many limitations. kdenlive has its own faults, including that its documentation is not always clear and one must refer to it constantly when figuring out the UI (hint: video tutorials were so useful to understanding the docs). Essentially, I can now do almost anything I need to with kdenlive now, but I would greatly appreciate it if the devs could improve rendering time, update the dvd creation wizard to support blu-ray, and add more rendering options (for example, ogv output does not support quality levels, only bitrates). As for stability, I saw several crashes when I was first exploring features, but none since.

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.
Introducing Lightworks, it’s a commercial video editing suite for Linux, Mac and Windows. It’s a non-linear tool with a completely different approach to editing video. Instead of a simple GTK or Qt window that is manipulated by the desktop environment (and themed by it too), the app offers up a full screen editing environment. Lightworks isn’t free. In fact, unlike the other apps on this list it actually requires a monthly subscription to use but it’s worth it if you want to edit and produce video on Linux.
