Just like OpenShot, it is incredibly easy to learn and use this software. Flowblade gives its users the features of video transitions, watermarks, batch rendering, and drag & drop support. In addition to that, it also supports various image/audio/video formats. It also supports proxy video editing. As I already mentioned, it’s a method of editing in which original media clips are presented on a timeline by proxy clips for light-weight editing. The full resolution of the video will be used while wrapping up the project.

Also, one of the thing I love from Linux is the variety in the distros. What’s the problem with that? Canonical is doing a great effort to come to home users, more than RedHat or Novell… use then a Debian-based distro like ubuntu, but let us the rest of the people with our distros, with our beloved desktop or window manager… anyway, it doesn’t affect to aplications since we all can compile from source (at least in my case, because I use gentoo and I must always compile from sources), and you can find binaries for debian-based or rpm-based distros.

Davinci Resove is another non open source video editor for linux, like Lightworks. It used to be a very excellent color grading software, and now, it's a great video editor as well. You can do all the basic editing and some of the advanced editing on the free version (multi-camera editing, 3D editing, motion blur effects, and spatial noise reduction, etc are only available on the paid version)

Shotcut is anther video editing software for Linux and it is an interesting one because its UI looks more like a media player than an editor. The software makes editing video very simple with the set of awesome features it has. For basic uses, it will work just fine, but if you need more powerful options, especially for advanced or professional video recording, then it may not be the best. However, with the features it has, it qualifies as a decent video editor for Linux.

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.
