Free app that will help you perform multilayered realtime video manipulation
Version: 0.10FreeJ is a vision mixer: an instrument for realtime video manipulation used in the fields of dance teather, veejaying, medical visualisation and TV.
Operating System: Mac OS X
FreeJ lets you interact with multiple layers of video, filtered by effect chains and then mixed together.
Controllers can be scripted for keyboard, midi and joysticks, to manipulate images, flash animations, movies, particle generators, live cameras, text scrollers, and more.
All the resulting video mix can be shown on multiple and remote screens, encoded into a movie and streamed live to the internet.
