When it comes to green screen compositing, spill suppression is one of those final touches that can make or break your shot. DaVinci Fusion offers several ways to remove green spill from your footage, the most common method being the Matte Control node. While the Matte Control node can get the job done quickly, it doesn't always give you the level of control you might need, especially when it comes to preserving luminance and customizing the spill color.
In this post, I want to share a more advanced method of de-spill that gives you infinite control over how your spill is removed, without compromising the quality of your plate.
What's Wrong with the Traditional Matte Control Method?
The Matte Control node is a great tool for quick de-spill fixes, but it has its limitations. The biggest issue is that it can often darken your footage as it suppresses the spill. This happens because the node replaces green pixels with neutral or desaturated colors, but in the process, it can unintentionally lower the overall luminance of those areas.
If you're working on professional compositing projects, losing luminance is never a good thing and it can break the realism of your final shot if you are matching it with a CG render.
The Infinite Control Method
The method I use bypasses the Matte Control node entirely and gives you full creative freedom over your spill suppression.
Instead of simply removing green, this setup allows you to:
Isolate the spill color using the Delta Keyer and Channel Booleans.
Neutralize the color or tint it to any color you want.
Preserve the original luminance of your plate.
This approach not only gives you a more flexible result but also opens up new creative possibilities, like matching spill colors to your environment or adding subtle artistic tints to your composite.
Why This Method Is Better
Full control over the spill color
No loss of luminance
If you're serious about compositing, having this level of control is a game-changer, especially on more complex shots where every pixel counts.
