LiVES is a simple to use yet powerful video effects, editing, conversion, and playback system aimed at the digital video artist and VJ. It runs under Linux, BSD, Mac OS X/Darwin, IRIX, and openMosix. It is frame and sample accurate, can handle almost all types of video, and is fully extendable through plugins and the included plugin builder tool. It can also be controlled remotely using OSC.
Kdenlive is a non-linear video editor for KDE. It provides all project management and editing tools while relying on a separate rendering framework (currently MLT/FFmpeg) to perform the editing operations. Kdenlive provides dual video monitors, a multi-track timeline, and clip list. Other features include customizable layout support, basic effects and transitions, multiple file formats, and full project and asset management support. Editing in Kdenlive is possible with various tools via the timeline and video monitors, allowing you to move and resize one or more clips, and razor clips into two. All timeline tools can snap to clip start/ends and the current seek position. You may playback/preview the contents of the timeline at any point during the edit. Kdenlive communicates with a render engine which handles the actual video data.
