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.
Pierre, did you not see the mention of Blender??? It is GREAT for doing video. Yes, you do have to learn it but you want to do a good job right?? One thing to note. It is best in blender to turn the movie into a series of stills in the openEXR format. It is also important to go into settings and increase the buffer memory so that you get a much faster response as it loads much more movie at one time. Make sure to render the firm into its own director or you will have a LOT of picture files cluttering some other directory! Also more Ram mean better responsiveness and having a SSD drive is also a GREAT benefit. I would think this is true of any system.
The problem average people have with Cinelerra is that it is truly complicated and requires time spent learning about the real underpinnings of video production technology in order to use it to its full potential. But the learning is worth it. What a person learns by digging deep into the intricacies of video production will allow a deeper understanding of what is going on with even “hand-holding” software.
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.

Not exactly going to be a long term con. The official website clearly states the same, which is why this piece of software should not be used for important projects. Then again it is so damn good that Olive editor is right now my primary editor for most projects. The fact that there is NO stable version of this software does bother a bit as it's ability to handle complex projects is almost unpredictable. But all said and done, it's still not crashed on me even once. Even though an alpha, the best damn alpha release ever. See More

Audio and video clips can be linked together and managed as single clip. Another thing that I personally find useful is that Pitivi can be used in different languages and has a very extended documentation. Learning how to use this software is easy and doesn’t require much time. Once you get used to it, you will be able to edit video and audio files with high precision.
Simply wonderful! One of the few cross platform video editors that has lightning fast editing preview without having to create proxy clips for every step owing to GPU preview. A huge advantage considering the amount of time saved in having to not wait for proxy clip generation thereby allowing for a more flexible workflow. Beautifully blended workflow combining a bit of premiere and a slight bit of after effects. Having the control to edit content visually by resizing or moving clips and other elements directly on the editor / viewer gives a tremendous amount of creative freedom. See More
Coming from a film editing background I *know* how to edit, it’s just the tools I need to master. It should not be that hard. What’s finally pushed me over the edge is that the windows codec is broken (I have the worst lemon version of XP you can imagine) so that I can’t even see the images for the thousands of hours of video I have recorded with my Canon camera in the premium video editing software available for Windows But I can’t replace the codec because Windows thinks it works, so it won’t reinstall. Which is too bad because I slaved to learn that bloody commercial editing software that cost a bomb and got quite good at it. But intuitive? No way, Pierre.
The easiest answer is perhaps the lack of commercial applications for desktop Linux, even for a popular distribution like Ubuntu. There is no shortage of quality desktop apps like LibreOffice, Firefox, GIMP and VLC – even Minecraft runs perfectly well with OpenJDK Java – but when it comes to multimedia creation, Linux desktop distributions still left behind. With no Photoshop, After Effects, Ableton Live, or Premiere Pro for Linux, we have to turn to alternatives. For image editing, GIMP and Inkscape have Linux pretty well covered, while Bitwig and Ardour meet most Linux audio editing needs. Thus, here follows my review of a few readily available Linux video editing software (I tested them on an up-to-date Ubuntu 18.04 LTS 64-bit system.) This list is not in order from best to worse or vice-verca. As I completed the test for one Linux video editing software, I wrote it down and ranked it based on my experiences.
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)
Trey has a good point, I don’t want to do much more than combine my video with a few transitions and a soundtrack. Kdenlive works fine for that. My biggest issue with Linux video editing is the lack of good transitions and simple drag and drop functionality. Also DVD menu creation is still really poor on Linux. But over the last four years it has gotten much better.
Blender is the 3D computer graphics software. It is also open source and freely available, mainly used for visual effects, video games, animated films and 3D interactive application. This software is written python, c and c++. This software has main features such as skinning, 3D modeling, texturing, UV unwrapping, smoke and fluid simulation etc. some of specially for computer graphics in video editor that are rendering, video graphics editing, animating, sculpting, compositing, match moving, camera tracking, particle and soft body simulation. Also supports primitive's geometric including 3D vector graphics. Its special scan-line ray tracing can export in various variety system for internal render engine.
I’m so pleased with this software that I have been paying a monthly membership fee ever since my free trial expired. I use Content Samurai for YouTube affiliate marketing. You can too. Just add a link to your affiliate offers in your video descriptions. I also turn plr articles into videos. That’s right, I don’t have to write anything. I just create videos from plr content.
