The delta keyer is at it’s core a color difference keyer which blackmagic added to Fusion 9. It is probably one of the most advanced and most customizable keyer in Fusion and it can be used together with a clean plate input. An additional clean plate generator is available as well. When using the delta keyer, your basic workflow will follow these steps:

  1. Select background color or clean plate
  2. Adjust pre-matte ranges (if not clean plate), erode pre-matte if it is too tight.
  3. Adjust matte with threshold values and clean foreground / background
  4. Adjust the despill settings and take care of edges in the Fringe tab.

In this comprehensive tutorial, I will show you how to use the keyer and how to fine tune your matte and final image with all settings available in this new tool. I will also provide a little bit of background information about color difference keyers by showing a very basic version of a color difference keyer created purely from channel booleans and a color corrector (fusion file in download package).
