Projects / FreeJ


FreeJ is a vision mixer: an instrument for realtime video manipulation used in the fields of dance and theater performance, veejaying, medical visualization, and TV. With FreeJ, multiple layers can be filtered through effect chains and then mixed together. The supported layer inputs are images, movies, live cameras, particle generators, text scrollers, and more. The resulting video mix can be shown on multiple and remote screens, encoded into a movie, and streamed live to the Internet. FreeJ can be controlled locally or remotely from multiple places at the same time, using a slick console interface. It can be automated via JavaScript and operated via MIDI and joystick.

          •  05 Aug 2005 12:10

            Release Notes: Encoding in Ogg/Theora has been implemented so that FreeJ can now save to a movie file or stream live to an online Icecast2 server, while audio is being recorded as well from the soundcard. The scripting API has been improved, and various library dependencies are now included statically for easier and more portable source builds.
