Blender is an open source software 3D animation program. It can be used for modelling, uv unwrapping, texturing, rigging, skinning, animating, rendering, particle and other simulating, non-linear editing, compositing, and creating interactive 3D applications. Blender is available for several operating systems, including Microsoft Windows, Mac OS X, Linux, IRIX, Solaris, FreeBSD, SkyOS, MorphOS and Pocket PC. Blender has a robust feature set similar in scope and depth to other high-end 3D software such as Softimage|XSI, Cinema 4D, 3ds Max and Maya. These features include advanced simulation tools such as rigid body dynamics, fluid dynamics, and softbody dynamics, modifier based modeling tools, powerful character animation tools, a node based material and compositing system and an embedded scripting engine based on Python.
Cinelerra, the first Linux based real-time editing and special effects system is a revolutionary Open Source HD media editing system. Long developed by Heroine Warrior with vital assistance from LMA, Cinelerra gives you real-time 1080p editing and compositing power on a state-of-art Linux video workstation. Developed for AMD64 OPTERON technology, the LMA CINELERRA system is a powerful and highly productive workstation for adding cost effective hardware and Linux software for Video and film production studios. The LMA CINELERRA system will support SMPTE-292 and SMPTE-259 native 10-bit resolution – the maximum resolution allowed in SMPTE SDI standards on OPTERON. CINELERRA was the first media editing system ported to support the AMD OPTERON 64 bit technology. CINELERRA has a number of effects built into the system including numerous telecine effects, video special effects including compositing, and a complete audio effects system. Cinelerra is featured on the APRO, the first 64 Bit Intellistation ever offered by IBM.

FFmpeg is a collection of free software that can record, convert and stream digital audio and video. It includes libavcodec (a leading audio/video codec library), and libavformat (a leading audio/video container mux and demux library). FFmpeg is developed under Linux, but it can be compiled under most operating systems, including Windows. The project was started by Gerard Lantau, a pseudonym of Fabrice Bellard, and is now maintained by Michael Niedermayer. It is notable that most FFmpeg developers are also part of the MPlayer project, the VLC/VideoLAN project, plus one member of the xine project, and that FFmpeg is hosted at the MPlayer project server.
Jahshaka aims to become a cross-platform, open source, free, video editing, effects, and compositing suite. It is currently in alpha stage, supporting realtime effects rendering, but lacking useful implementations of many features such as the non-linear editing system. It is written using Trolltech’s Qt, but its user interface is written using an OpenGL library to create GUIs.
Kdenlive is a video editing GUI for KDE using the MLT video framework. Kdenlive provides dual video monitors, a multi-track timeline and clip list. Other features include customizable layout support, basic effects and transitions.
Kino is a non-linear DV editor for GNU/Linux. It features excellent integration with IEEE-1394 for capture, VTR control, and recording back to the camera. It captures video to disk in Raw DV and AVI format, in both type-1 DV and type-2 DV (separate audio stream) encodings.
LiVES began in 2002 as the Linux Video Editing System. Since it now runs on more operating systems, LiVES is a Video Editing System. It is designed to be simple to use, yet powerful. It is small in size, yet it has many advanced features.
PiTiVi is an open source video editor, written in Python and based on GStreamer and GTK+. PiTIVi provides several ways of creating and modifying a timeline.
