Abstract

In this workshop you will learn the basics of Coollab, a node-based software designed to be very easy to use, yet very powerful. We will explore the various types of effects (image generators, shapes, 3D, distortions, post-processing, etc.), and then learn how to make your scene react to audio! The explanations will be followed by some practice time, where participants will create their own procedural music video based on a short music excerpt.

Participants should bring a laptop with Coollab installed, and ideally some earphones. No prior experience required. For the room I just need a screen/video-projector with an HDMI cable.
