Delta Keyer and Clean Plate Tool

Delta Keyer and Clean Plate Tool

The delta keyer is at its core a color difference keyer which Blackmagicdesign added from Fusion 9 onwards. It is 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 the download package).

The green screen video from this tutorial can be downloaded from Hollywood Camera Wrok. (On the page, check for “SINGLE MARKER PAN/TILT” and “GODIVA WIDE”)

    Great content. This is what I was thinking about, when earlier this morning, giving feedback to your free DR Fusion beginners course, a detailed look at a tool and its many parameters.

    Excellent tutorial. Very useful. Much appreciated!
