Cinelarra has two versions: the unsupported community version and a commercial edition. Every six months the nice Cinelarra developers release the latest source code. It’s not widely available in the usual distro repositories, but the good Cinelerra-CV folks bundle it up into Arch, Debian, Fedora, Ubuntu, and other distro packages. There is a Cinelarra PPA— Personal Package Archive– for Ubuntu users. PPAs are user-supported repositories for specific applications, like Cinelarra. They’re not official repos, but they allow you to use your normal Ubuntu package manager to install and remove third-party software.
The only criticism I might have for Kdenlive is that it looks like an open source program. It isn’t the most user-friendly application to work with and appears to have been programmed by someone who knows what they are doing but expects you to also know what they are doing. It isn’t the most polished experience, and some things seem to be a bit obtuse to do.
Kdenlive is an intuitive and powerful multi-track video editor, including most recent video technologies. Kdenlive supports all of the formats supported by FFmpeg (such as QuickTime, AVI, WMV, MPEG, and Flash Video), and also supports 4:3 and 16:9 aspect ratios for both PAL, NTSC and various HD standards, including HDV. Video can also be exported to DV devices, or written to a DVD with chapters and a simple menu. Kdenlive packages are freely available for GNU/Linux, FreeBSD and Mac OS X under the terms of GNU General Public License version 2 or any version later.
I wanted to use a Linux first, open source editor but I rely on stability for work and sadly I couldn't get a workflow that didn't include a significant number of crashes and glitches. DaVinci Resolve on the other hand is absolutely stable, never crashes, never glitches, has excellent tools, a smooth workflow and incredibly fast rendering. IMO better than Premiere. See More
Like you, I’ve never been able to keep Cinelerra open for more than 10 minutes but in my case, the reason wasn’t the ugly UI. The problem is rather that it is a total crashfest! I do not know a single piece of software under Linux that exhibits that many lockups, race conditions, segfaults etc etc. Heck, on my system, it can’t even load a project that it saved 2 minutes earlier without crashing and that sadly ruins the featurewise winner of the competition completely.
LiVES is a free video editor developed for Linux operating system. It has a blend of real-time video performance and non-linear editing. It enables users to edit and make videos without worrying about the video formats, rates, frame sized, etc. Furthermore, it also performs as a Video Jockey software because of its multitrack timelines, mixing of clips and switching.
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)
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.
