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.
Looking to quickly edit a video on Linux? Consider using Shotcut. It’s a non-linear, cross-platform, multi-track video editing tool that is great and easy to use. The video editor has support for adding titles, cutting and splicing clips together, as well as keyframe options, and more. It’s certainly not as complex as something like Lightworks, or as user-friendly as OpenShot, but it’s a solid editor that can get the job done. If you’re looking for a competent video editing tool, Shotcut might be a great choice.
