Pierre and Megan, you’ve been trolling these comments for two full years, now. I can see, after carefully reading all of the commentary and the thought behind each of them, that you both are only here to troll and discourage. Neither of you have offered any real concrete proof of anything, and you’ve used smoke and mirrors to try to defend merely what are empty opinions. After two full years of trolling this particular page it’s about time you both got told to get a life.

You’re missing the point; ‘nix has its place. Our servers run on it. My netbook runs it. My web development is done on it. Our databases run on it. But I don’t have time to “try” this bit of software or that software for video editing in the hope that it will provide the magic bullet. In any case, as I have stated elsewhere, every video editing program I have tried on linux has one or more severe failings in respect of the things I need to do. Attempts at creating robust video editing software on linux are, IMO, amateurish.
Cinelerra is the most advanced non-linear video editor and compositor for Linux. Cinelerra also includes a video compositing engine, allowing the user to perform common compositing operations such as keying and mattes. Cinelerra includes support for very high-fidelity audio and video: it processes audio using 64 bits of precision, and can work in both RGBA and YUVA color spaces, using floating-point and 16-bit integer representations, respectively. It is resolution and frame rate-independent, meaning that it can support video of any speed and size.
Do all this in a basic newly opened blender session. Then click save as default. Then when you open a new blend you will always have these presets select. If you do this mid work in some blend you are working that blend will become your default (almost never what you want to do). You might also want to skim through the addons. Blender has a lot of power that comes turned off by default but nothing much for film editor.
LiVES (LiVES is a Video Editing System) is a free software video editing program and VJ tool. LiVES mixes realtime video performance and non-linear editing in one professional quality application. It will let you start editing and making video right away, without having to worry about formats, frame sizes, or framerates. It is a very flexible tool which is used by both professional VJ’s and video editors – mix and switch clips from the keyboard, use dozens of realtime effects, trim and edit your clips in the clip editor, and bring them together using the multitrack timeline. You can even record your performance in real time, and then edit it further or render it straight away.
Vidnami promises that you can “Create Stunning Videos Fast” with their app. You can use Vidnami 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 Vidnami a shot.
