The Touch Engine implementation allows you to route up to 8 video inputs (2 on a layer) to the Touch Designer component and use that video in the component. The system will only process these inputs if the loaded component requests them saving system resources. To enable these inputs in your component please see the later section entitled Creating Components for Hippotizer
There are 2 selectors for each video input, the first selects which mix or viewport contains your source video, and the second selector allows you to select which layer or mix master you want to get the video from.
*The video source will be provided before any geometry or colour correction.
