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.
Far from the “it just works” dream, this program just does not work. I have a relatively fast i7 laptop with plenty of RAM, but OpenShot slowed my entire system to a crawl as soon as I started to edit some video. Firefox became unresponsive and OpenShot crashed or at least appeared to do so since a crash report window opened but OpenShot did not close.
