The DaVinci Resolve 3D Keyer
A First Look at the new keying controls in DaVinci Resolve 12
One of the headline color correction features in DaVinci Resolve 12 is the new ‘3D Keyer’. What’s it good for? Here’s what the manual has to say about it:
The 3D keyer is a good one to start with if you’re trying to isolate a range of color such as a blue shirt, a cyan sky, a performer’s skin tone, or the orange leaves of a tree in autumn. Its interface of drawing lines over the part of the image you want to isolate, coupled with its high quality and extreme specificity, make it a fast and accurate tool to use in a variety of circumstances.

The manual also tells us that the 3D Keyer is *always* looking at the Luma, Saturation and Hue components of the image.
Unlike the HSL / RGB Qualifier, you can’t just pull a Hue-only or Luma-only key with the 3D keyer
Its simplicity is its strength. Adding to its strength—it has a sampling colorspace all its own…
The 3D keyer let you flip between HSL and YUV colorspace sampling (YUV is default). The HSL / RGB Qualifier doesn’t have a YUV option, giving you – the ‘in the know’ colorist – another colorspace to try and pull a quick key without futzing around too much with all the controls and sliders. As you may know, one of my cardinal rules in color correction: “If at first you don’t succeed, try, try again… but don’t dawdle. If it fails, try a different technique, quickly!”
The 3D Keyer works best if you accomplish your initial key in under 3 swipes
The 3D Keyer lets you sample ranges of pixels. You can build up your samples by adding the pixels from one swipe while subtracting the pixels in another swipe. It’s very easy to keep swiping, adding and subtracting areas you want—or don’t want—in your key. Before you know it you have 8 swipes and a still-ugly key.
As you’ll see in this Insight… I’m coming to the conclusion that being ‘swipe happy’ is a bad habit. In fact, my best results with the 3D Keyer are when I combine a single swipe with an adjustment of the Tolerance control, except…
There is no tolerance control in the 3D Keyer. Or is there?
In this First Look you’ll learn the rules I’m using to find success with the 3D Keyer
And the one adjustment that doesn’t work quite like its name suggests but seems to be critical for pulling clean keys quickly.
Like learning any tool, the more you use it the more you refine your workflow… and I’ve only had Resolve 12 in my hands for a few weeks. And since this is a Public Beta 1, it’s possible some of these controls will be renamed or revised—at which point I’ll revisit these, my initial thoughts.
At this point in Resolve 12’s release cycle, my goal for you is to have you working much more quickly, and with purposeful intent, when using this new feature of DaVinci Resolve.
