Blender is the open source software for 3D modeling, animation, rendering, post-production, interactive creation and playback. Available for all major operating systems under the GNU General Public License.

Blender therefore is fully free to use and distribute within any educational, professional or commercial environment. Artwork created with Blender - including python scripts - is the sole property of the creator.

For the open movie production called Elephants Dream six experienced artists/developers have worked in Amsterdam for seven months to create an exciting short 3D movie with Blender. Not only the movie itself has been be published under the Creative Commons, all the production files as used for the movie are included as well, free to be reused.
Version used in second course of TOSMI 2008.

Cinelerra does primarily 3 main things: capturing, compositing, and editing audio and video with sample level accuracy.

For years some people have wanted a way to edit their audio and video in one place as fluidly as writing text. Cinelerra tries to be a single location for all your audio and video editing needs. All the recording, editing, and playback are handled here. It can be used as an audio player. It can be used to record audio or video. It can even be used as a photo retoucher.

There are two types of moviegoers: producers who create new content, going back over their content at future points for further refinement, and consumers who want to acquire the content and watch it. Cinelerra is not intended for consumers. Cinelerra has many features for uncompressed content, high resolution processing, and compositing, with very few shortcuts. Producers need these features because of the need to retouch many generations of footage with alterations to the format, which makes Cinelerra very complex.


GIMP is an acronym for GNU Image Manipulation Program. It is a freely distributed program for such tasks as photo retouching, image composition and image authoring.

It has many capabilities. It can be used as a simple paint program, an expert quality photo retouching program, an online batch processing system, a mass production image renderer, an image format converter, etc.

GIMP is expandable and extensible. It is designed to be augmented with plug-ins and extensions to do just about anything. The advanced scripting interface allows everything from the simplest task to the most complex image manipulation procedures to be easily scripted.

GIMP is written and developed under X11 on UNIX platforms. But basically the same code also runs on MS Windows and Mac OSX


Ardour is is a digital audio workstation. You can use it to record, edit and mix multi-track audio. Produce your own CD’s. Mix video soundtracks. Experiment with new ideas about music and sound. Generate sound installations for 12 speaker gallery shows.

Ardour capabilities include: multichannel recording, non-linear, non-destructive region based editing with unlimited undo/redo, full automation support, a mixer whose capabilities rival high end hardware consoles, lots of plugins to warp, shift and shape your music, and controllable from hardware control surfaces at the same time as it syncs to timecode. If you’ve been looking for a tool similar to ProTools, Nuendo, Cubase SX, Digital Performer, Samplitude or Sequoia, you might have found it.


Dr. Queue : In a generic way, DrQueue is tool to distribute tasks through a farm of networked computers. There is a queue of jobs that are composed by different number of tasks represented by numbers.

From the point of view of distributed rendering, those tasks usually represent frames, and the task number is also the frame number.

Thus, all frames composing the different jobs (using different job scripts) are queued awaiting to be assigned to a slave. Once assigned, the slave will execute the job script to produce the resulting frame. After that, the task will be marked as done and the slave will be freed to render other frames.

In case of a slave failure or script error, the master node will notice and requeue the frame again to be rendered by another slave.


Subversion is a free/open-source version control system. That is, Subversion manages files and directories, and the changes made to them, over time. This allows you to recover older versions of your data, or examine the history of how your data changed. In this regard, many people think of a version control system as a sort of “time machine”.

Subversion can operate across networks, which allows it to be used by people on different computers. At some level, the ability for various people to modify and manage the same set of data from their respective locations fosters collaboration. Progress can occur more quickly without a single conduit through which all modifications must occur. And because the work is versioned, you need not fear that quality is the trade-off for losing that conduit—if some incorrect change is made to the data, just undo that change.


Trac: Trac is an enhanced wiki and issue tracking system for software development projects. Trac uses a minimalistic approach to web-based software project management. Our mission is to help developers write great software while staying out of the way. Trac should impose as little as possible on a team’s established development process and policies.

It provides an interface to Subversion, an integrated Wiki and convenient reporting facilities.

Trac allows wiki markup in issue descriptions and commit messages, creating links and seamless references between bugs, tasks, changesets, files and wiki pages. A timeline shows all project events in order, making the acquisition of an overview of the project and tracking progress very easy.
