Live Video Mixing

vimix performs graphical mixing and blending of several movie clips and computer generated graphics, with image processing effects in real-time.

Its intuitive and hands-on user interface gives direct control on image opacity and shape for producing live graphics during concerts and VJ-ing sessions.

The output image is typically projected full-screen on an external monitor or a projector, but can be streamed live (SRT) or recorded (no audio).

vimix is the successor for GLMixer - https://sourceforge.net/projects/glmixer/
