Getting Great Greenscreen Keys Using Fusion’s Delta Keyer

Fusion’s Delta Keyer: An incredibly powerful but misunderstood tool

When I first started using the Delta Keyer in Fusion – I never seemed to get the results I was expecting. Keys took a lot of tweaking, and it always seemed harder than it should be.

This got me thinking of one of my overall philosophies when it comes to just about any type of workflow:

“If you are working really hard – there is probably a better way to approach the problem”.

Understanding the delta in ‘Delta Keyer’

Turns out – I was using the Delta Keyer completely wrong!

‘Delta’ refers to the difference between two things, and differences are exactly what this powerful keyer exploits to make great keys.

Instead of removing a single color from the background, the Delta Keyer subtracts a clean version of the greenscreen, including its imperfections and nonuniformities. This eliminates many of the normal pain points of greenscreen keying – but requires you to have a clean plate – or a shot of the greenscreen with nothing in the foreground.
