Basic Qualification Using the HSL Keyer
The HSL qualifier is one of the most flexible tools in DaVinci Resolve. Using any combination of
sampled hue, saturation, and luma, you can isolate different ranges of color and contrast for
specific adjustment. HSL is a general-purpose keyer, meaning you can key any color you like;
it’s not restricted to blue or green.
The most straightforward way to use any qualifier is to sample the image in the Viewer. A set of
four controls let you sample pixels within the image in different ways. When you sample one or
more pixels, the Hue, Saturation, and Luma values are analyzed, and set different ranges in
each of the Hue, Saturation, and Luma qualifier controls. There are a number of different
eyedropper controls available to control how you sample color in the image.
 Sample Eyedropper: The first control you use whenever sampling the image. It defines
the initial range of the qualification; you must use this tool before any of the others.
Clicking once with this tool selects a single pixel value, while clicking and dragging
selects a range of image values that add together.
Color Picker button
 Add/Subtract Color Range: These two controls let you add areas of the image to, or
subtract them from, the currently selected inner range of values that define the core
of the key. As with the eyedropper, you can click on single pixels, or drag over a range
ofcolor.
Add and Subtract color buttons
 Add/Subtract Softness: These two controls let you redefine the softness that
transitions from the inner range of the key, falling off towards the outer edge of the key.
Just like the other controls, you can click on single pixels, or drag over a range of color.
Add and Subtract qualifier softness
NOTE: When you select one of the sampling controls, it remains selected until you
select another sampling control. If you select another clip in the Timeline, then click in
the Viewer to sample a key and nothing happens, make sure that you select the
Eyedropper control in the Qualifier palette.
If you’re working with the DaVinci Resolve onscreen interface, the easiest way to qualify a
subject is to use the pointer in conjunction with the sampling controls.
