Johannes Timpernagel, Robert Pohle and Sebastian Huber have just completed the music video for the saxophone quartet sonic.art from Berlin using a combination of analogue and digital techniques. The team filmed the four members of the quartet last year in Hamburg in front of a green screen. After that, they created a audio-reactive vvvv-Drawing-Application, which tracks the contour of the video footage and combines it with drawings by using a Wacom-tablet. The last step was to draw this generative animations on paper and combine them with hand-drawn sketches of the musicians. Johannes says it was a long journey and the vvvv-App a essential one of the progress of creating this video.
