Cinelerra *had* the most promise and it’s probably good if you want to run a TV station. However, it’s not creative at all. Simple edits are easy. However, anything else can become a stunt. IMO, Kdenlive has seen the quickest growth. Lives is also doing well. In the next few years we may see those apps grow into the free alternative of Finalcut – but not Cinelerra. It does what it does, and there is no need to change.
The option to group multiple video and/or audio tracks is absolutely marvelous for use with multiple view angles and sound tracks. This permits you to modify all the tracks at the same time and prevents the need to constantly re-synchronize your clips. KDENlive can also edit multiple selected tracks at once without grouping them, which permits great flexibility when changing edits. See More
It supports high-definition video, Blu-Ray, 3D, tethered shooting, integration of video, audio, and still images, all the usual effects such as scrolling titles, pans, and fades, animations, speed changes, audio mixing, export to multiple formats and quality levels including YouTube and Vimeo, and tons more. It is under active development and has great community support. This may be the only video program you’ll ever need.
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)
It has been a long known fact that there is a larger variety of software products for Windows and Macs compared to Linux. And even though Linux is continuously growing it is still hard to find some specific software. We know many of you like editing videos and that you often need to switch back to Windows in order to make some easy video editing tasks.
Hi! I'm Zohaib Ahsan, contributor to FOSS Linux. I'm studying computer science, I’ve learned a thing or two about operating systems that are based on Linux. This has made me join FOSS Linux where I can share what I have learned with the rest of the world. Not to mention — some major tea is going to be spilled as well — as I share with you the latest developments in the world of Linux.
