Applying effects is as easy as drag and drop. But if you want to edit them, you'd need to right click on each clip and select Properties. You'd need to experiment with not-so-well documented parameters which take forever to preview just to see if you are on the right track. It is sort of easy to learn unless you want more than drag and drop controls. See More
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!)
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.
Looking to quickly edit a video on Linux? Consider using Shotcut. It’s a non-linear, cross-platform, multi-track video editing tool that is great and easy to use. The video editor has support for adding titles, cutting and splicing clips together, as well as keyframe options, and more. It’s certainly not as complex as something like Lightworks, or as user-friendly as OpenShot, but it’s a solid editor that can get the job done. If you’re looking for a competent video editing tool, Shotcut might be a great choice.
