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:
- Select background color or clean plate
- Adjust pre-matte ranges (if not clean plate), erode pre-matte if it is too tight.
- Adjust matte with threshold values and clean foreground/background
- 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).
