Negative Node
 
 
 

The Negative node generates the negative of a source image. The colour values of each pixel in the source image are inverted to produce the negative image. In the Modular Keyer, this is mainly used to invert the matte.

You can add a Negative node to any part of the processing pipeline.

To use the Negative node:

  1. Add a Negative node to the schematic.
  2. Switch to Parent edit mode.
  3. Connect a source to its Front tab.
  4. Connect the output to the input tab of the next node on the branch.
