Kino is a non-linear DV (digital video) editor for GNU/Linux. It features integration with IEEE-1394 for capture, VTR control, and recording back to the camera. It captures video to disk in RawDV and AVI format, in both type-1 DV and type-2 DV (separate audio stream) encodings. You can load multiple video clips, cut and paste portions of video/audio, and save to an edit decision list (SMIL XML format). Most edit and navigation commands are mapped to equivalent vi key commands. Also, Kino can load movies and export the composite movie in a number of formats: DV over IEEE 1394, Raw DV, DV AVI, still frames, WAV, MP3, Ogg Vorbis, MPEG-1, MPEG-2, and DivX. Still frame export uses Imlib1, which has built-in support for PPM, JPEG, PNG, TIFF, GIF, and whatever your ImageMagick installation supports.
Veejay is a visual instrument and real-time video sampler. It allows you to "play" the video like you would play a piano. While playing, you can record the resulting video directly to disk (video sampling). Veejay can be operated live by using the keyboard (which is completely user definable) or remotely over TCP/IP. Veejay can be used to manipulate video in a realtime environment such as visual performances or for (automated) interactive video installations.
Blender is a free 3D animation studio. It includes tools for modeling, sculpting, texturing (painting, node-based shader materials, or UV mapped), UV mapping, rigging and constraints, weight painting, particle systems, simulation (fluids, physics, and soft body dynamics and an external crowd simulator), rendering, node-based compositing, and non linear video editing, as well as an integrated game engine for real-time interactive 3D, and game creation and playback with cross-platform compatibility.
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.
iVideo is multitrack video editing software, created in Cocoa (Objective-C) and using QuickTime. It was developed for all general video purposes, and to include all of the features of QuickTime Pro and iMovie. It is almost complete; you can import video from digital cameras (using FireWire) or from any QuickTime format supported file, then edit, modify, and mix them, and apply any video effect on or between them. You can then export them to any QuickTime supported format.
LVE provides frame and GOP accurate editing of MPEG1/2 elementary ("ES") and program streams ("PS"), including VOB format. The cutting engine is based on a frame server (demuxer), which guarantees exact and fast seeking to every frame. The GUI is based on libSDL. Video scenes are handled as thumbnails movable by drag and drop. Final videos can be build with or without re-encoding. Tools for shrinking and DVD authoring are also available.
