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.
Using Linux does not mean that you can’t have high-quality software on your system. Apart from the video mentioned above editors, there are tons of other software available in the market for Linux. Some of them are aimed at professionals (just like Lightworks, DaVinci Resolve, and Blender), while others cater to the requirements of beginners (similar to Shotcut and VidCutter). Moreover, you will also be able to easily download and install video editors on your Linux system, as most of them are already available on the app store.
I have a small favor to ask. More people are reading the nixCraft. Many of you block advertising which is your right, and advertising revenues are not sufficient to cover my operating costs. So you can see why I need to ask for your help. The nixCraft takes a lot of my time and hard work to produce. If everyone who reads nixCraft, who likes it, helps fund it, my future would be more secure. You can donate as little as $1 to support nixCraft:
People who dislike Linux usually say that it’s not great for professional, high quality video production and as a result the industry ignores it and doesn’t take it seriously. This isn’t entirely true.  It is very much a fact that Apple Computer will never release Final Cut Pro for Ubuntu, and Adobe will never make a FlatPak version of Premiere, but it doesn’t matter. Some commercial, professional video editing tools do find their way onto Linux.
