Pro Colorist answers questions on using qualifiers in DaVinci Resolve.

0:06 Introduction
8:24 What is the difference between using a qualifier for specific luma regions and
using the HDR wheels that are built in Resolve?
11:46 Is the qualifier color space aware? How does the qualifier work in a large color
space vs display space?
20:33 What are your thoughts on other kinds of qualifiers, such as the RGB or the
3D qualifiers?
29:46 Is there any kind of footage besides 8 bit that we should avoid putting a
qualifier on? And what kind of footage is appropriate to use qualifiers on?
38:19 How can we use power windows to only target the background of the image
when an element in the foreground interferes with the background?
42:49 How to deal with qualifying something that has a very similar value in the
background and in the foreground to create separation?
49:09 Does the RGB qualifier convert into an HSL qualifier if we move to the HSL
color space?
52:56 Do you use qualifiers when working with brands who demand an exact color
reproduction in their brand colors?
56:51 Using linear color space sounds good when using certain OFX such as
halation or glow but linear has values that go beyond 1. How to deal with that
problem?
1:01:11 Using the ‘’Hue’’ slider in the HSL qualifiers creates a tighter selection than
using the Hue vs curves, even when softening a lot the selection, which may cause
artifacts in the image. Why does that happen?
