Feature wise, Cinelerra looks to be the best fit if you want to do anything serious, and that’s a problem, because it falls apart when doing anything serious thanks to a seriously bug ridden code base. I mean it! This thing is such a race-condition fest, it can’t even open its own project files on my system without crashing! (Start project, add clip, save it, try to load it … freeze!)
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.
Blender 2.8 makes video editing a LOT easier (start UI, easy to drag file, left click select...). It's still a bit harder to learn than other tools but for power users each shortcut you'll learn can be applied almost everywhere (e.g. pressing "i" on a numeric field to keyframe the value, or "g" to grab and move and element...). It's very powerful especially if you want to also include 3D in your videos. However many standard tasks will take more time in Blender: The preview is slow, to do a high quality zoom in animation you may need to use a Compositor or instead crop, rendering in 10 bits requires a lot of temporary disk storage, video stabilization is also a pain... Overall I'd suggest it more for someone interested in 3D doing also video editing. See More
This video editing software offers customizable layout support, a clip list, a multi-track timeline, automatic backup, keyframe special effects, and transitions. Are you using any unique file format or camcorder? Not a problem — Kdenlive supports almost everything available. It should also be mentioned Kdenlive supports Mac OSX and FreeBSD as well. Another important feature is the Proxy editing. This cool feature can automatically create low-resolution copies of your source clips to allow light-weight editing, and then render using full resolution.
Content Samurai promises that you can “Create Stunning Videos Fast” with their app. You can use Content Samurai video creation software to turn articles, blog posts and shorter pieces of content into videos in minutes, or so the creators claim. I’ve spent a lot of money having freelancers create videos for me, so I figured I would give Content Samurai a shot.
